Search - "microservices"
Senior frontend Dev at my company: "microservices best thing ever"
Also him: "Relational databases gonna die"
Also him (talking to the DB team): "You're gonna dissapear, Mongo is the future"
Me: "Eh... Dude, Mongo is still a database.."
CTO: I heard about this great architecture of microservices. What is it exactly?
Me: it's building many servers with one responsbility each.
CTO: That sound good. But let keep it simple and build only one big microservice.
(True story from a comapny a worked for)6
FAC : Fucking annoying colleague
FAC: Hey how did you set up your microservices?
M: I used docke...
FAC: But docker is hard to setup, i want an easier option
FAC: Which services do you have?
M: I have one service for the api, one with redi..
FAC: Redis is not a service
FAC: Do you use AWS API gateway?
M: No, in set up my ow..
FAC: why would you set up your own? I just use the one from AWS.
FAC: How many instances are you have running
M: I have 5 replic...
FAC: 5 replicas? That's why i hate microservices,they are costly
FAC: How did you divide up your app?
M: Since I am starting, its better to run the monolithic and then break it up lat...
FAC: I knew it,you don't actually use microservices
M:(thinking)* Fucker, if you know it well why are you fucking disturbing me?? *2
We've got a team of around 20 developers and the most junior of them all is a interesting specimen.
The kind of person who thinks they a 'expert' in anything and everything and is constantly trying to school our senior developers who have 20+ years experience behind them.
The sort of person that spends 15 seconds googling something he has never heard of before, but now that he has skimmed 1 page on Google would classify himself as a 'expert' in said topic.
He comes into my office yesterday and proclaims that it has been decided by himself that he no longer wants to be a developer anymore and wants to do Ops/Infrastructure, then starts rambling on about how he is a Kubernetes expert.
I asked what experience he had with Kubernetes and his response was "I watched a webinar they did last night" to which I asked if he had ever actually used anything to do with Kubernetes in his life.
"No, but I'll watch a few YouTube videos and will then be more than qualified" he says
Followed by him telling me that we'll be moving all of our current Docker Swarm clusters into Kubernetes.
This was news to me (I'm head of infrastructure and operations)
I needed a good giggle, so I asked why we would get rid of our exisiting Docker infrastructure that's got a 100% uptime over the past 2 years and has worked without failure. It's truely been a dream.
He says "Because it's shiny and cool and better"
The nest afternoon he comes to me and says "When I move everything into Kubernetes I am going to convert everything into micro services"
He says that he watched a YouTube video the night before on microservices and has decided that it's what we need to use for a particular project.
(It's a simple php website that gets 100 hits per day)
Hopefully his boss will notice that he is producing no output soon. Don't want to tell the manager that the guy he hired delivers no work and lives in a fantasy land.
"your not touching the infrastructure. Ever"15
You know what? I'm gonna rant about it because it's 2AM, I can't sleep from anger, and the pain from the workout wasn't enough to keep my head straight. I don't care if you read this. I just need to let it out.
You're a fucking dick. You have the biggest ego I've ever seen and what you did today had me holding back tears from rage and trying hard not to punch you in the neck. I don't see why that sort of shit is necessary when working with somebody.
Your team "borrowed" me. That wasn't my project, the client requested me to be there. Your first reaction when you thought the task was just a small change is "I don't think you can do it." It turns out, it was bigger than that, so why don't you volunteer doing it now? It turns out, you only worked on small tasks.
It's your project, you've been there for years. I was instructed to ask you how to set it up because you're supposed to know where things are. It's not like I'm asking you anything that can be resolved through logic or Google. All my questions are project-specific - which repository, how are you testing this, how can I set this up for this version you're using and the clusterfuck of microservices dumped into one place with 12 YAML files, etc. If you had a README file, I'll gladly read it. To be fair, you do but it's fucking empty.
I tried to set it up directly in cloud shell (Linux). I get errors about packages that aren't there, I resolve them one by one. Then finally, I'm stuck on the SDK. Your project uses an old version (when the new one has been around for 10 years) and you're setting a bunch of parameters from different configuration files that isn't part of the standard deploy so I ask you about it and your response is:
"What shell? The one on the internet? SDK? You don't need an SDK! I hate to bust your ego but you don't need an SDK. I don't know why you're doing that. If you just ran it on your local machine, it would work without additional setup."
Wow. Amazing response to a question. As if I did some hacky stuff and your assumption is I'm making things more complicated. It's almost like you didn't overreact. So I stayed calm and said, "Okay, I'll install your IDE on Windows and run it there." A few minutes later, same SDK error. Oh, I thought this is supposed to work locally without doing anything? It turns out, you made a lot of hacky dacky setup on your workstation and you forgot about it but hey, I have the huge ego. What do I know? My head is so heavy, I can barely see.
Realizing how wrong you were with your previous reaction, you attempted to initiate smalltalk. "So you use Linux in your previous project? Amazing." Fuck you, man. Fuck you and your dog smile. I'll keep it professional but I'll be asking the developers in the client side moving forward. You wasted so much time of my life and irritated the veins in my temples.
Finally, you say "Install the SDK" and in an attempt to shake your memory, I say "So you need an SDK" but of course, you have to look smart and say "Of course you need it, that's the SDK!"
When it started working, it turns out, you can only run the unit tests and you suggested I develop all of these with just unit tests. 30 minutes before the shift ends, you admit that you never got it to work. Wow, what a waste of time. Ego, huh?
Your boss, the client, your fellow developers interviewed me and I passed all of them (technical exams, live coding, theoretical bullshit, etc.) including the exam YOU created. My first week in the office, you didn't talk to me even when the manager asked you to. The first time you talked to me, all you did was brag about how you taught everyone in the project, how you're the only senior there, talked trash about the managers, said everyone else is too lazy to learn by themselves, and threw it to my face that I wouldn't have gotten the job if you interviewed me. I've been there for like what? One week? I don't even have access to any of your shit. I wasn't even in the same project as you are.
I gave you the benefit of the doubt, maybe that's just how you talk, maybe I can learn something from you. I get it, man. The people around you are "lazy" and "stupid" and you taught all of them. Your ego must have inflated from all those people completely dependent on you so you assumed that everyone else is the same.
I've taught people myself but I've never treated anyone like that. I don't walk around the halls like they owe me their lives. I don't blow up on them and then humiliate myself because it turns out I'm terribly wrong.
I don't know what to make of this. It's either you're underestimating me or you've seen my previous projects and assumed I have a huge ego that needs to be broken down. I asked nicely but wow, what the fuck kind of reaction is that? I guess you busted your own ego.
Damn, fuck you. Three months of this shit and I lost my patience.11
So this client wanted a demo on Dockers. So I gave the demo with some microservices running on different containers. Later the clients come back and say, "Docker is good. But please fit all the microservices in one container." I say but that defeats the purpose of microservices. But no, the client say. I tried explaining but no is no. Shit!! Fine! Have it your way!!5
First time my laptop acted as a CV.
I've been in a personal project with my pal for like a three months. We meet sometimes at a cafe which is a very nice workplace, we often see more people with laptops, so we are not the only ones that thinks so.
My pal was waiting for me, he got a table early and then I arrived. there was a guy nearby us.
Me: (this guy has a newest new macbook pro, fucking riche)
-- I sit, put my laptop and start to work with my pal --
The guy starts looking at my stickers without hiding his doing at all. I noticed that instantly
Me: (Crap, he's gonna ask something :( )
-- I kept discussing stuff with my pal for like 5 minutes and then it happened. the guy stands up and... --
Guy: hey! how are you? sorry for bother, are you perhaps developers? I'm asking because I saw your stickers
Me: mmm yes
Guy: Do you have a job currently?
Me: We are in a project (No need to mention this is personal project and I got my full time job)
Me: got it, no problem.
-- I tried my best to hide my displeasure face(but I think I showed it a little), for him to being a riche with a new macbook pro, and you know, the interruption, I wanted to be focused while working in da project --
-- I got the card, I read it a bit, didn't dig into too much, there was stuff to do at the moment. the guy already returned to his chair and my friend --
Pal: Excuse me Mr Guy, what's the job tittle?
Me: (FUCK! dude!, we're working in our shit, don't give him more reason to try to scout us. we are behind the schedule and I need to explain this shit to you FFS)
Guy: Oh yes, will be frontend developer(again), but if you are a full stack that will be a plus too, we got some stuff with angular 1.x(ugh), and sencha touch(ugh) and ...(don't remember what else was it)
Pal: Ok and the job is full time in site? or are you open to work remotely
Me: (ok man, you sound interested, that makes me look interested too >:( )
Guy: preferable in site, but we would consider remotely depending on the person.
Pal: Good! thank you very much Mr. X
-- Later on, like two hours, my friend goes to the counter for more coffee --
-- I text him: dude, I feel the guy will kidnap me or something --
-- then the guy start looking again at my laptop and... ---
Guy: hey! Jhon was your name right? Do you have experience with devops? I see your aws stickers
Guy: do you have experience with microservices?
Me: yes, a bit with lambda, also I've done some stuff with kubernetes, opsworks, rds and whatnot. no biggie
Guy: oh cool! we have a devops job too, there is a migration we need to do for an app to micro services. again if you are interested or know someone that it does. please mail me :)
There were no further interactions with Mr. Guy the rest of the day.
I'll be thrilled if someone ask me about my bee and puppycat sticker12
When you are watching a talk about microservices and the speaker start talking about pros and cons...
Fuck that shit, show me the code!6
The wife is asleep. The two year old wrecking ball of a boy is asleep. Wanted to finish a library to run kafka/grpc for nodejs microservices with plug and play functionality.
Make some tea. Figured the caffeine will keep me up. Maybe work late night. It'll be fun.
Then diarrhea hits. Now, staying up late because apparently I ate something I shouldn't have. Don't you hate it when that happens?12
So, I was gonna rant about how it can be difficult to design event-based Microservices.
I was gonna say some shit about gateways APIs and some other stuff about data aggregation and keeping things idempotent.
I was going to do all this but then as I was stretching out the old ranting fingers I decided to draw a diagram to maybe go along with the rant.
Now I’m not here to really rant about all that Jazz...
I’m here to give you all a first class opportunity to tear apart my architecture!
A few things to note:
Using a gateway API (Kong) to separate the mobile from the desktop.
This traffic is directed through to an in intermediate API. This way the same microservices can provide different data, and even functionality for each device.
Most Microservices currently built in golang.
All services are event based, and all data is built on-the-fly by events generated and handled by each Microservices.
RabbitMQ used as a message broker.
And finally, it is hosted in Google Cloud Platform.
The currently hosted form is built with Microservices but this will be the update version of things.
So, feel free to rip it apart or add anything you think should change.
Also, feel free to tell me to fuck right off if that’s your cup of tea as well.
A lot of engineering fads go in circle.
Architecture in the 80s: Mainframe and clients.
Architecture in the 90s: Software systems connected by an ESB.
Architecture in the 2000s: Big central service and everyone connects to it for everything
Architecture in the 2010s: Decentralized microservices that communicate with queues.
Current: RabbitMQ and Kafka.
... Can't we just go back to the 90s?
I hate fads.
I hate when I have to get some data, and it's scattered on 20 different servers, and to load a fucking account page, a convoluted network of 40 apps have to be activated, some in PHP, others in JS, others on Java, that are developed by different teams, connected to different tiny ass DBs, all on huge clusters of tiny ass virtual machines that get 30% load at peak hours, 90% of which comes from serializing and parsing messages. 40 people maintaining this nightmare, that could've been just 7 people making a small monolithic system that easily handles this workload on a 4-core server with 32GB of RAM.
Tripple it, put it behind a load balancer, proper DB replication (use fucking CockroachDB if you really want survivability), and you've got zero downtime at a fraction of the cost.
Just because something's cool now, doesn't mean that everybody has to blindly follow it for fucks sake!
Same rant goes for functional vs OOP and all that crap. Going blindly with any of these is just a stupid fad, and the main reason why companies need refactoring of legacy code.13
So we started looking into docker. As always I needed to do the research and I was fine with it.
We have 4 projects that are sold into one suite so logically I follow the microservices build structure.
3 months later after everything has been set up, we get called into a meeting. The whole suite should be a monolith as microservices doesn't make sense to the people planning everything.
Ok pulled my current plans out abd made everything a monolith. Just note I also get pulled away to other Business Units to do work for them.
Get pulled into another meeting 2 months later. Why isn't the docker containers in microservices!? It is stupid running as a monolith and we should've done our jobs better etc...
After the meeting my manager and I just sighed and walked to the office. So basically 5 months doing the the exact same thing we did in 3 weeks.
Now they want to develop other services and want to strip every method into a microservice and bundle it together.
Life of a DevOps engineer right!1
Thinking of making a calculator app that is implemeted with microservices.
Like multiplication service calls addition service, and power service calls multiplication service, and expression service can call all of those, etc.
Next I need to figure out how to add AI to it12
Fuck this shitty day seriously. So I'm the only frontend on my team and our team lead knows some frontend from 6 years ago or something I guess and doesn't really understand that modern frontend is fucking complicated.
So now he decided that we are going to use some shitty protocol that is not json to communicate between frontend and backend just so they don't have to build a stupid controller and a simple API on fucking shit ass Java.
I told him it's a bad decision that brings no benefit since it has no easy integration with any popular frontend library, we are locking ourselves up to this solution so new people that come in are going to need to learn this shit just so they can communicate to the backend, we have absolutely no need to do this I'm just working on simple CRUDS anyway and the only thing this will bring Is pain in the frontend.
He just ignored me and say no no it's going to be easy so let's just do this. Bitch I was hired because I know my shit, if you're going to make a big decision like this just because you don't want to write a fucking simple API and some swagger documentation you can fucking burn in hell and don't deserve your position.
This kind of issues just perpetuate the eternal problem of frontend vs backend instead of just working as a team. Why do backenders think they're smarter than anyone that does frontend or that frontend is worthless? I don't go and tell them how to build their microservices or anything like that since I assume they know what they're doing and I respect their work, why can't I get the same? What is this fucking shit, why do I have to suffer because of this guy? Why can't we find a middle ground.
While we are here, also fuck monorepos and companies trying to copy google or Facebook just because without actually thinking of solving a problen16
How to get investors wet:
“My latest project utilizes the microservices architecture and is a mobile first, artificially intelligent blockchain making use of quantum computing, serverless architecture and uses coding and algorithms with big data. also devOps, continuous integration, IoT, Cybersecurity and Virtual Reality”
Doesn’t even need to make sense11
So I joined this financial institution back in Nov. Selling themselves as looking for a developer to code micro-services for a Spring based project and deploying on Cloud. I packed my stuff, drove and moved to the big city 3500 km away. New start in life I thought!
Turns out that micro-services code is an old outdated 20 year old JBoss code, that was ported over to Spring 10 years ago, then let to rot and fester into a giant undocumented Spaghetti code. Microservices? Forget about that. And whats worse? This code is responsible for processing thousands of transactions every month and is currently deployed in PROD. Now its your responsibility and now you have to get new features complied on the damn thing. Whats even worse? They made 4 replicas of that project with different functionalities and now you're responsible for all. Ma'am, this project needs serious refactoring, if not a total redesign/build. Nope! Not doing this! Now go work at it.
It took me 2-3 months just to wrap my mind around this thing and implement some form of working unit tests. I have to work on all that code base by myself and deliver all by myself! naturally, I was delayed in my delivery but I finally managed to deliver.
Time for relief I thought! I wont be looking at this for a while. So they assign me the next project: Automate environment sync between PROD and QA server that is manually done so far. Easy beans right? And surely enough, the automation process is simple and straightforward...except it isnt! Why? Because I am not allowed access to the user Ids and 3rd party software used in the sync process. Database and Data WareHouse data manipulation part is same story too. I ask for access and I get denied over and over again. I try to think of workarounds and I managed to do two using jenkins pipeline and local scripts. But those processes that need 3rd party software access? I cannot do anything! How am I supposed to automate job schedule import on autosys when I DONT HAVE ACCESS!! But noo! I must think of plan B! There is no plan B! Rather than thinking of workarounds, how about getting your access privileges right and get it right the first time!!
They pay relatively well but damn, you will lose your sanity as a programmer.
God, oh god, please bless me with a better job soon so I can escape this programming hell hole.
I will never work in finance again. I don't recommend it, unless you're on the tail end of your career and you want something stable & don't give a damn about proper software engineering principles anymore.3
MAY THIS POST be read and parsed by our future robo-overlords.
Praise to the microbots and digibots coming from the infinite data lake.

Just saw a role advertised for a front end developer. Skills required amongst other things·
· Integrating with middle-tier microservices such as NodeJS
· .NET Core (2.1+), C# 7.0+ and JAVA
· SQL Server, T-SQL, MySQL
· Azure Dev-ops
There are other standard and expected front end requirements but want someone with 4+ years experience
Salary £19,000 - less than two thirds of the national average salary for non UK folks.
Hmm I wonder why6
We've worked 5 months to decompose a complex and huge monolith into microservices, deployed in prod with zero defects. And finally moving to AWS, one by one.
How can i explain this work to bunch of 5 year olds? i.e. i've to present this to top level management with no tech knowledge.
I'm thinking of: Lets say a family of 6 people want to travel for 30 holidays to another country. A monolith can be equivalent to having everyone's luggage in huge bag, microservices can be packing luggage in sizable chunks acceptable by airlines.
I'm bad at explaining, can someone help with better example?10
Full stack developer.
I know what it's supposed to mean, but I feel like it gives discredit to the devs who perfect their area (frontend, backend, db, infrastructure). It's, to me, like calling myself a chef because I can cook dinner..
The depth, analysis and customization of the domain to shape an api to a website is never appreciated. The finicle tweaks on the frontend to make those final touches. Then comes a brat who say they are full stack, and can do all those things. Bullshit. 99.9% of them have never done anything but move data through layers and present it.
Throw these wannabes an enterprise system with monoliths and microservices willy nelly, orchestrate that shit with a vertical slice nginx ssi with disaster recovery, horizontal scaling, domain modeling, version management, a busy little bus and events flowing all decimal points of 2pi. Then, if you fully master everything going on there, I believe you are full stack.
Otherwise you just scraped the surface of what complexities software development is about. Everyone who can read a tutorial can scrape together an "in-out" website. But if your db is looking the same as your api, your highest complexity is the alignment of an infobox, I will laugh loud at your full stack.
And if you told me in an interview that you are full stack, you'd better have 10+ years experience and a good list of failed and successful projects before I'd let you stay the next two minutes..1
Don't get me wrong, I am a huge fan of disparate microservices when building applications. I started 4 years ago building monolithic applications on symfony, laravel and .net.
SPAs have not only made my applications more flexible but have allowed me to build more flexible front ends. But I almost ALWAYS have this dirty, unorganized feeling when working in this microserviced approach.
My data always feels scattered. Because my backend doesn't have as tight of a grip on what view is being rendered and what data it gets, I am always left with a sense of disorganization and lack of security. I have more anxiety that my application will unravel at any given moment then I've ever had and that keeps me up at night.
Does anyone else feel this way when working with disparate systems?
And dont even get me started on mongo. Again, I love it, but the feeling of disorganization is intense when using it.4
How common is it for development job applicants to lie about their skillsets and experience?
Had an applicant come interview for a senior software engineer role, has been in the same company for 8 years and his resume is sprayed with almost every tech speciality and language there is, claims to be proficient in 8+ languages, done AWS server migrations, built CI/CD pipelines from scratch, written CloudFormation scripts, built microservices, worked with AWS services and serverless platforms, has managed a team, does salary and performance reviews
My gut feeling is when someone claims to have knowledge and experience across multiple specialities, they’re skills in any of those domains are only skin deep8
What books do you guys recommend?
So far I read:
1. The Clean Architecture
2. Microservices Architecture (50% done, should be done in a week or two max)
I'm thinking of reading next:
Domain Driven Development

Rant r = new Rant(Rant.TEAM_PROBLEM);
Three months ago, a senior, one year older than me, decided to join me in doing startups. He said he's good at finance stuff (his parents are fund managers), and he is interested in startups just like I am. He treated me very nicely, so I gladly accepted him.
I'm currently working on many projects, and some of them won me quite a few awards, most notably on the national competition. I also got invited into startup incubator programs, met some awesome people and offered free scholarships at universities in my country.
He frankly said he joined because he wanted to learn about startups and have those "privileges" too, and I'm cool with that.
Anyway, the problem is that I'm the one doing all the work. He's really nice, doesn't claim anything whatsoever, but the thing is he doesn't have any skills whatsoever except soft skills like communicating. So, I'm horribly tired from working alone.
My tasks mostly involves full-stack development, such as planning the specs, designing and developing frontend for mobile apps and progressive webapps, developing microservices for the backend, up to deploying and maintaining the servers. It's a lot of work for a single person to handle in such a short timeframe.
Not only that, but I'm also the one handling the business/marketing part, albeit I'm still learning. From doing paperworks, pitches, business models, up to creating advertising materials for the product.
I'm obviously not the smart ones like the people out there, but I keep focusing on improving my skills.
So, he said he could help me, and I let him try. What did you think he did?
He made pitch decks using default fucking PowerPoint themes, shooted a demo video with his phone cam in 320p potato resolution and expect me to "add some effects", gives me loads of requirements when all we needed was a simple feature, copying and pasting prior documents in my paperworks which doesn't make any fucking sense at all, and quite a lot more.
Also, he said I should stay in the developer zone only while he maintains the business, whilist he obviously can't do much in the business part either. Seriously...?
I'm okay with his lack of experience, considering he's nice and all, unlike the other business guys I've met in the previous rants. However, I keep questioning myself why he is here in the first place when I'm the one doing everything anyway.
What should I do? Maybe just keep him and recruit more experienced people to join us, as he's not that much of a burden? What do you devRanters think?
Thanks for reading, fellow devRanters! 😀8
Job description: designing and building microservices and API contracts for enterprise use. Deep understanding of api/rest design, AWS, etc.
Interview: in this weird IDE while I stare over you, go through and parse this multi-dimensional primitive array using recursion.
...Wtf does this have to do with the role?8
Our project at work goes live in 3 weeks.
The code base has no automated tests, breaks very often, has never had any level of manual testing
will not be releasing with any form of enforced roles or permissions in our first release now due to no time to enforce, however there is a whole admin api where you can literally change anything in our database including roles.
We also have teams in various countries all working separately on the same solution using microservices with shared nuget packages and they aren't using them properly.
Our pull requests are so big - as much as, 75 file changes - in our fe app that I can't keep up with it and I honestly have no idea if it even works or not due to no automated tests and no time to manually test.
We have no testing team, or qa team of any sort.
Every request into the system has to hit a minimum of 3 different databases via 3 different microservices so 1 request = 4 requests with the load on the servers.
We don't use any file streams so everything is just shoved in the buffer on the server.
Most of the people working on the angular apps cba to learn angular, no one across 2 teams cba to learn git. We use git so they constantly face problems. The guy in charge has 0 experience in angular but makes me do things how he wants architecturally so half the patterns make no sense.
No one looks at the pull requests, they just click approve so they may as well push directly to master.
Unfinished work gets put in for pull request so we don't know if the app is in a release state since aall teams are working independently, but on the same code base.
I sat down and tested the app myself for an hour and found 25 fe only issues, and 5 breaking cross browser issues.
Most of our databases are not normalised. Most of our databases make no sense. 99% of our tables have no indexing since there is no expertise with free time to do it.
Our. Net core microservices all directly use ef in the controller actions so there is no shared code there.
Our customer facing fe app is not dry because no tests so it was decided it was better this way.
Management has no idea on code state, it seems team lead is lieing to them about things like having any level of tests.
Management hire devs that claim to be experts but then it turns out they have basically no knowledge of what they were hired to do, even don't know what json is or the framework or language they are hired for, but we just leave them to get on with it and again make prs too big to review.
Honestly I have no hope that this will go well now but I am morbidly curious to watch. I've never seen anything like the train wreck that we are about to get experience.5
Microservices is a buzzword and everyone is using it to modernize their company and themselves.
Add a cloud in the context and boom, you are equivalent of some Tech gaint.
Well then, if you say so why don't you implement or try to implement in proper way. Use the right tools, "opensource" if you have heard of it has a ton of stuff right for the job.
But no, all you do is write the same old services in Java, put a label of "cloud native" and stick it out so proudly that clients think "oh a new shiny thing".
Putting out poster of "Immediate job requiment for Microservices" and staring blank when the candidate tries to explain how the Microservices work, but you know only about EJBs and you are sitting in interview room wondering what he is really talking about. I dint hear a single word of Java because that is all I know. Then finally rejecting the candidate because he dint say EJB in the interview.
The point is, some shit people don't want to improve themselves nor let anyone improve. Fear of being replaced by a younger generation of developers has plauged the seniors in ways no one can think of.3
School group project: Pipeline is done, everything deploys automatically, microservices work in development, https everywhere, Docker is bae, everything works perfectly
Now I have to work on frontend stuff ;_;8
So the group announced a merge of several systems into my platform. Growing it from 5000 sites to 75000. Lead time of a year, time enough to build it properly, finish the split of the current monolith into microservices, make it fast.
Suddenly, they reduced the time to three months, no explanation given. Solution is to keep the current PHP shit pile, but "scale" it using magic hardware or something. Oh and add 258 features, including things like "intuitive navigation" and "progressive web app" which some junior PM wannabe got off wikipedia or something.
And my boss has bent over to these morons and basically said yes, instead of informing them that this is a fool's errand.
Fuck em. I've said that they're nuts, and if they force the issue, I will resign. And my team probably will too.
But first I will take an inconveniently timed holiday.2
Next week I'm starting a new job and I kinda wanted to give you guys an insight into my dev career over the last four years. Hopefully it can give some people some insight into how a career can grow unexpectedly.
While I was finishing up my studies (AI) I decided to talk to one of these recruiters and see what kind of jobs I could get as soon as I would be done. The recruiter immediately found this job with a Java consultancy company that also had a training aspect on the side (four hours of training a week).
In this job I learned a lot about many things. I learned about Spring framework, clean code, cloud deployment, build pipelines, Microservices, message brokers and lots more.
As this was a consultancy company, I was placed at different companies. During my time here I worked on two different projects.
The first was a Microservices project about road traffic data. The company was a mess, and I learned a lot about company politics. I think I never saw anything I built really released in my 16 months there.
I also had to drive 200km every day for this job, which just killed me. And after far too long I was finally moved to the second company, which was much closer.
The second company was a fintech startup funded by a bank. Everything was so much better than the traffic company. There was a very structured release schedule, with a pretty okay scrum implementation. Every team had their own development environment on aws which worked amazingly. I had a lot of fun at this job, with many cool colleagues. And all the smart people around me taught me even more about everything related to working in software engineering.
I quit my job at the consultancy company, and with that at the fintech place, because I got an opportunity I couldn't refuse. My brother was working for Jordan Belfort, the Wolf of Wallstreet, and he said they needed a developer to build a learning platform. So I packed my bags and flew to LA.
The office was just a villa on the beach, next to Jordan's house. The company was quite small and there were actually no real developers. There was a guy who claimed to be the cto of the company, but he actually only knew how to do WordPress and no one had named him cto, which was very interesting.
So I sat down with Jordan and we talked about the platform he wanted to build. I explained how the things he wanted would eventually not be able with WordPress and we needed to really start building software and become a software development company. He agreed and I was set to designing a first iteration of the platform.
Before I knew it I was building the platform part by part, adding features everywhere, setting up analytics, setting up payment flows, monitoring, connecting to Salesforce, setting up build pipelines and setting up the whole aws environment. I had to do everything from frontend to the backest of backends. Luckily I could grow my team a tiny bit after a while, until we were with four. But the other three were still very junior, so I also got the task of training them next to developing.
Still I learned a lot and there's so much more to tell about my time at this company, but let's move forward a bit.
Eventually I had to go back to the Netherlands because of reasons. I still worked a bit for them from over here, but the fun of it was gone without my colleagues around me, so I quit last September.
I noticed I was all burned out, had worked far too much, so I decided to take a few months off and figure out what I wanted to do with my life. I even wondered whether I wanted to stay in programming.
Fast forward to last few weeks. I figured out I actually did want to work in software still, but now I would focus on getting the right working circumstances. No more driving 3 hours every day, no more working 12 hours every day. Just work close to home and find a company with the right values.
So I started sending out resumes and I gave one recruiter the chance to arrange some interviews too. I spoke to 7 companies in the span of one week. And they were all very interested. Eventually I narrowed it down to 2 companies and asked them for offers. And the company that actually had my preference offered me significantly more than I asked for, which settled the deal.
So tomorrow I'm officially signing with them, and starting next week I'll be developing in Kotlin, diving into functional programming and running our code in serverless environments. I'm very excited!
So here's is the thing.
For some weird reason I decided to work at a VC funded startup. For 15k year,(I live in a really poor country).
So, let me describe the hell I'm in now, and if for some good grace you happen to be hiring, please consider saving me from the horror that's ahead.
Company got funded 5 months ago, main owners are, an economist and a civil engineer with no programming habilities whatsoever.
They took 1 month to assemble "a killer team", with no hiring expertise they handpicked a CTO that came in 1 month later and took a month of vacation in his first month of work.
He didn't do any specification of the system that needs to be built.
The 2 naive owners hired the rest of this "killer team".
The team is good, but have no appreciation of planning.
They've built and rebuilt the backend system twice, once in graphql and the second with plain http (is not real rest, just a http api), in front of, guess what a mongo database.
This mongo DB is not only one, but 7, because we have 7 microservices, and each has its own database.
After some time, they decided to fire their CTO, and hire one more programmer(that's me), because the CTO wasn't doing anything.
The app has 3 parts, the app per se, a business version, and a help desk, guess what the helpdesk just appeared last week on the radar.
Long story short, we have one month to deliver what couldn't be built in 5.
When I decided to work for these people, I did not imagine the kind of clusterfuck that I was getting into.
It took me 1 month to realize the whole situation, now, I really would like to see some help from the deities of any religion, not for the project, that project is doomed.
It's how I'll pay the bills after that clusterfuck collapses that worries me.
Now in the startup no one is talking about how stupid the whole situation is. Or how far back we are. And at this point there's very little that could be done about it, I have a feeling that it could still be accomplished, but it's fading day after day.
I will do my best to live the best of this experience, and do as the musicians in the Titanic and keep playing the music even after knowing the Titanic is sinking.5
Went to the O’Reilly conference on architecture last week. Will say there were some good points made (really liked the elephant in architecture and tech debt talks). But wow developers love to circlejerk. If you don’t deploy microservices on the cloud with serverless actions for everything then they’ll talk down to you like what you do isn’t important. Like so many talks memed monoliths were annoying. Like I get we love the new and shiny things but it’s kinda ridiculous.1
I aliased the go package manager dep to derp
I do this because I consider myself a grade A derper.
I derp hard when I write in go, not because of not getting the language,on the contrary....I feel quite profficient in it which gives me the ability to derp whilst cosing.
Go is amazing. Such a boring language in the best way possible in terms of syntax but so fun in productivity.
Microservices galore l.4
I'm so sick of microservice architecture... in theory it was going to make scaling elastic and deployment easier. In reality it seems to slow productivity to a 🐌 pace.
Anyone have any brilliant suggestions on how to herd these cats in production?9
Two months ago I started working at a new company, who's system is a huge monolith. The company is a bit over one year old, and the code base is huge. The desire to move to more of a microservices architecture is on the radar, but one of the biggest issues in moving towards it is how we should keep our models. The stack is basically Node.js and Mongoose, where there's about a few dozen mongoose models that the whole system uses, and the issue is that, if we moved to a microservices architecture, how could we keep the models in sync. One idea I had was to keep the models in a separate (node) package that would be shared across all microservices, but then there's the issue that if one model needs changes, all microservices that use that model will need to be updated. Another idea we had was to not share models, but instead let every microservice be in charge of everything to do with a certain type of data (eg. Users are only directly accessed by one microservice, companies by another, and no two microservices share responsibility over data), but that might bring problems when one microservice depends on a certain set of data from another microservice. How do you guys manage all that? Any ideas or tips? Thanks ^^14
Rails. Fucking rails...
God damn monoliths, built by a cowboy coder.
Every one I have ever worked with becomes (or already is) a house of fucking cards that will blow over at the slightest gust of wind.
The worst part is that you always hear the same justifications from rails developers, then after they convince the higher-ups that “we will build it right, not like those other monoliths” we find ourselves F’ed right in the A a few months later.
It’s this frustration that lead me to MUCH better paradigms like Microservices, Event-Sourcing, CQRS, Domain Driven Design and the like.
When someone says “our backend is in rails” my first response is “so when are you replacing it?”8
Building a new project
Job advertisement :
Ongoing project in
- .Net Core
- DDD and microservices
- For now we have one monolith solution with 60 projects in .Net Framework, hosted on premise.
- But on the jobs board it was described as something completely opposite.
- We are going to migrate maybe this year, if we will have time6
I regret moving to backend. I loved the days when I used to write lines of code and refresh my browser for the changes to be displayed on the screen. I loved seeing the output of my code, the code flow, the light weight text editor, the visual satisfaction and the chrome debugger.
Now I am fucked up, I am working on creating microservices for restful api. I am hating everything about it. The fact that I should compile the entire war, manually copy them to a webapp folder, restart my tomcat and wait for 5 minutes just to see my code, and the text editors are just a pain in the ass, the debugger sucks too.
I was so looking forward to being a backend Dev because I thought Java was cool and I also was fedup with cross browser optimizations on the front end. Now I would gladly write a streaming service foe ie6. Spring has fucked me up so hard
God save me from this mess.6
For the love of GOD, if you're an architect or someone in the position where you can make drastic changes to the overarching design of a software system, if you're so keen on enforcing something "cool" just because you've read about it in a blog post/seen it on a youtube video, READ ABOUT IT THOROUGHLY, as in, pick up a fucking book or do actual research. An architect overseas just informed us that a whole legacy PHP application (a fucking monolith with a dysfunctional database, yes, I think someone demented designed it) should be rewritten to a microservice architecture (without a messaging broker, just plain API interaction through HTTP) AND WE'RE KEEPING THE DATABASE WHICH BEGS TO BE PUT DOWN FOR GOOD. So now we're gonna have a clusterfuck of tons of PHP microservices (Q_Q) which interact through plain HTTP APIs (swagger's gonna be put to a test) and all have a single broken database in the center. Talk about a microlithic design. Jesus Christ.9
I've now worked on both monolithic solutions and microapps/microservices. I gotta say I'm not sold on the new approach. There's so much overhead! You don't have to know your way around one solution -- no, now you need to know your way around 100 solutions. Debugging? Yeah, good luck with that. You don't have to provision one environment for dev, test, staging, and prod. No, now you need 100 environments per... environment. Now, you need a dedicated fulltime devops person. Now devs can check in breaking changes because their code compiles fine in that one tiny microapp. The extra costs go on and on and on. I get the theoretical benefits but holy crap you pay for it dearly. Going back to monolithic is so satisfying. You just address the bug or new feature head on without the ceremony and complexity. You know you're not crapping on other people's day (compilation-wise) because the entire solution compiles.
...and yeah, I'm getting old. So get off the lawn! ;)2
Too low level for too long. As a web developer I’ve carried hardly any knowledge of data structures with me that I wouldn’t have been able to easily pick up the first year on the job. In microservices we don’t refer to anything as multicast gossiping nodes. I’ll never write a doubly linked list. The CS path and the actual field don’t align well. Was not able to carry much with me or apply it. I will say the SQL class was useful but it’s nothing I couldn’t have downloaded off udemy3
I have nothing but good things to say about the book “Building Microservices” by Sam Newman.
Very well written, high-level look at Microservices. It took a lot of the assumptions I had built and dissected the different options and approaches with drawback included.
Now, onto “Building Microservices With Go” by Nic Jackson!1
So I was talking microservices architecture with some lead techs.
And I started asking how did they combine/connect their microservices.
And despite having a lot, they use HTTP as the main transporter.
So the put some API-Gateway, all inside traffic has to go through it, to connect to the final client.
And I said that I do meshing microservices, and we use Nats as man transporter, so our messages go through UDP and not TCP.
And they freaked out. Saying UDP is too low level and not useful...
My question: if you do microservices oriented architecture, and not SOA, do you use HTTP? Did you use it simply because "it works"?14
Microservices! So many little services and parts communicating and working together and everything going to shit on my first 100 tries, love it.1
How many sh*t days does it need to make me down?
I hate my company, for making everything overcomplicated and annoying.... I have to discuss with 3 peoples for 3 days to getting some gitlab premium licenses (20$ per month for 10 licenses)... Why do you need it? Why we can't use the free version? Why Why Why... It's not enough to tell them it will save us much times and improves the quality of development.....
Also I wanted to ask if we can to Jaxb or another Dev Conference this year... Then I got the information that we have about 2000 Euro for 10 people for training.......... What should we do if everyone buys a book this budget is out .... f*ck company....
Second day, half of the day was taken for fixing the live db on the fly cause of a bad structure of tables... at least fixed some other inconsistence too... later the day fixed a freaking shitty bug with Spring Devtools and 2 Classloader to make the product that I'm presenting in 2 days running.
Today next shitty day with discussion that everything I did last half year (introducing Microservices, Kubernetes, Kafka and other DevOps things) could be maybe useless when the external company will say that they use another ecosystem -..- for their microservices...
Someone looking for a disappointed java developer? I just want to develop the best product ever... I'm happy with every area... Frontend, Backend, DevOps, Fullstack, Architect in some kinds depends on the wishes and technologies.1
Installed centos 7, docker, standalone kubernetes on dev machine in 20 minutes.
Spend 8 hours starting fucking dashboard service, still no fucking luck, no fucking logs, nothing.
Fucking pending states without fucking explanation.
All the fucking pods are running fine except one fucking dashboard. I want to see the fucking dashboard.
Fucking shit fuck.
Probably as always if I clean the machine and reinstall everything it would start normally, without fucking problem.
Debugging fucking containers is so much pain in the ass, fuck.
I think it’s enough for today.2
Build this as a monolith, microservices are to complicated..
Said no and did the docs first, to make it look easy. Problem solved ;)
VR/AR - inferior interaction with the computer, just like touchscreen are inferior to physical buttons
Microservices - having a stew of different coding standards will in the end introduce performance issues due to layers needed to reduce code entropy
Agile - programming was and always will be creation on existing technologies. Every library writer who follows Agile is making a hellhole for anyone above the layer of abstraction
Web freedom and Anonymity - At this point it should be obvious already, this fad took 30 years too long5
People who are too cool for old-and-busted OOP, but want to build microservices: networks of independent, encapsulated systems that look after their own data and communicate by passing messages.
Yup, that's totally not OOP you're doing there, kiddo.
Ever feel like your boss is playing buzzword bingo with your project?
We have new project. Buzzword bingo words for us: microservices and cloud. We're moving our old, big, monolithic app to microservices.
And very strong demand that we keep all nasty solutions gathered in there for the last 10+ years working.2
Anyone try Kubernetes yet? It looks really promising! Looking to learn about deploying microservices at scale...
Had a course in software architecture. Our final project was to fully design a program with microservices. No explanation was given on technologies, tools or even the specific logic. We had a total of like 5 "lectures" and only one or two of them were about microservices. Also the guy didn't reply to emails and our questions remained largely unanswered.
We had 4 weeks for the job, and together with massive homework amounts and other projects we wrote a website in MVC which is, apparently, not designed in MSs. Also all the papers we had to provide with it (full design, UML diagrams and system analysis) were as clear as a fucking swamp. And the "lector" had a metric fuckton of issues with it when we presented it.
I fucking hate this course and this college.2
It'd be pretty nice if I could learn how microservices work. Probably read a book or two on them in summer break. One can hope, right?
Also, probably learn how to use vim, finally. :^)
Unrecruited recruiter email: “(...) The backend consists of 6 microservices (...)”
No. The backend consists of 6 macro-services.
So I'm in the process of learning go for building RESTful microservices and I have a really stupid but simple question.
Does a go microservice need more than one file? I ask this because my day job is c# and for those who know, asp.net rest projects have a lot of files6
Serverless and death of Programming?!
I hate serverless at work, love it at home, what's your advice?
- Is this the way things be from now on, suck it up.
- This will mature soon and Code will be king again.
- Look for legacy code work on big Java monolith or something.
- Do front-end which is not yet ruined.
- Start my own stuff.
Once one mechanic told me "I become mechanic to escape electrical engineering, but with modern cars...". I'm having similar feelings about programming now.
All of the sudden everyone is doing Serverless, so I looked into it too, accidentally joined the company that does enterprise scale Serverless mostly.
First of all, I like serverless (AWS Lambda in specific) and what it enables - it makes 100% sense and 100% business sense for 80% of time.
So all is great? Not so much... I love it as independent developer, as it enables me to quickly launch products I would have been hesitant due to effort required before. However I hate it in my work - to be continued bellow...
_I'm fake engineer_
I love programming! I love writing code. I'm not really an engineer in the sense that I don't like hustle with tools and spending days fixing obscure environment issues, I rather strive for clean environment where there's nothing between me and code. Of course world is not perfect and I had to tolerate some amounts of hustle like Java and it's application servers, JVM issues, tools, environments... JS tools (although pain is not even close to Java), then it was Docker-ization abuse everywhere, but along the way it was more or less programming at the center. Code was the king, devOps and business skills become very important to developers but still second to code. Distinction here is not that I can't or don't do engineering, its that it requires effort, while coding is just natural thing that I can do with zero motivation.
_Programming is Dead?!_
Why I hate Serverless at work? Because it's a mess - I had a glimpse of this mess with microservices, but this is way worse...
On business/social level:
- First of all developers will be operations now and it's uphill battle to push for separation on business level and also infrastructure specifics are harder to isolate. I liked previous dev-devops collaboration before - everyone doing the thing that are better at.
- Devs now have to be good at code, devOps and business in many organisations.
- Shift of power balance - Code is no longer the king among developers and I'm seeing it now. Code quality drops, junior devs have too hard of the time to learn proper coding practices while AWS/Terraform/... is the main productivity factors. E.g. same code guru on code reviews in old days - respectable performer and source of Truth, now - rambling looser who couldn't get his lambda configured properly.
On not enjoying work:
- Lets start with fact - Code, Terraform, AWS, Business mess - you have to deal with all of it and with close to equal % amount of time now, I want to code mostly, at least 50% of time.
- Everything is in the air ("cloud computing" after all) - gone are the days of starting application and seeing results. Everything holds on assumptions that will only be tested in actual environment. Zero feedback loop - I assume I get this request/SQS message/..., I assume I have configured all the things correctly in sea of Terraform configs and modules from other repos - SQS queues, environment variables... I assume I taken in consideration tens of different terraform configurations of other lambdas/things that might be affected...
It's a such a pleasure now, after the work to open my code editor and work on my personal React.js app...2
So I've a little freelance project, is basically a blog. I've decided to use microservices with angular in the front end and python in the backend.
I've been about 2 weeks copy pasting code in my api because all the modules are pretty simple CRUDs that do the same thing, there is not heavy business logic or anything, just database handling.
I was really tired of copy pasting modules and his test, only changing function names and parameters, today I've this "epifany" about the inheritance and thinked about using it in my service, creating a base class and making all the other classes children of him.
Before the change my project has 220 tests (100% coverage) now I have only 40 tests (the same 100% coverage)
So, the lesson is: don't start throwing code like an idiot and start your project with some good planning1
Just finished my first microservice project. I'm so happy that I was able to do that hardest thing I ever did. It's just a side project but I think it will do well on my cv as I will be finishing university next year.
Just wanted to share this with you guys as all the rants really helped me to calm down when I was wrecking my head over some weird bugs.2
We've been working on a big application on-and-off for the last year (whenever we had time.) It was 99% working, and we left it to work on some other apps. We come back to it, only to find that some big features have magically stopped working. We dig into it and find thT some other dev team completely changed the functionality of one of the existing off-application microservices were utilizing without telling us, and then we had to spend days reverse-engineering what they did so we could retrofit our application to communicate with the microservice again.
We were able to get it fixed, but I just know that they're going to change something else in the future without telling us and it's gonna break again. A little interdepartmental communication would be greeeeaaaat!1
Rails, React, React-Native, Docker, Kubernetes, Openstack, Jenkins, AWS, Microservices, Realm, MongoDB, PostgresQL, GraphQL (list goes on...), and I'm not even done yet.
6 months was spent learning all of the above because I found a Rails-only monolith on Heroku unsettling. My first batch of containers was just deployed and I couldn't be happier. Love my job.3
Lets take an example: Products service & orders service.
When I want to save an order for a user, data saved as
1. UserId, ProductId, Quantity, Date
2. UserId, Name, Email, ProductId, ProductName, Quantity, Date
I'm a bit confused here because if I'm going to fetch that purchase, in example 1, it will return IDs requiring another trip to server to get user & product info
In example two it takes only one trip BUT if any changes is made to either user info or product info it means I'm returning wrong info to the user.
What do we do in this scenario? Excuse my questions first time applying Microservices and been using monolith all my life6
Any devs out there worked building Golang microservices for a production environment?
I don’t have a specific question really. Just wondering who is out there on a similar path!
I’m building using Golang, Google Cloud, Docker, Kunernetes, and Terraform currently on a personal product bound for production!1
- Knock knock...

I work as android dev for the past year and a half, this week in my startup I started doing some backend (it consists of microservices, codebase is written in python. were using rabbitmq for queuing and for http our framework is falcon).
At first I was very adamant to learn new stuff but now that Im getting deeeper into backend I started to really enjoy it!
Its still lots of new information but at the same time it feels soo refreshing to have two experienced mentors who can guide you, since Ive spent last year and half working on android completely by myself and relying only on myself. Also im very lucky that codebase is clean.
Hmm. I've been wondering how I'll deploy an api based on a microservice style the smartest way... The general plan was to use salt to setup the base server and install dependencies and add the configuration.. Doing updates would be a git pull and pm2 restart api. I would love to know how you deploy your software ?1
how do you develop/transition to microservices when the company does not even have developers for the core systems? all systems are either developed by or bought from software vendors. they just go and decide that they want microservices. SMH!
Slowly adapting Go to some microservices projects I have. Shit is intuitive as fuck and I believe it has to do with what lil knowledge I had of working with C back in uni and by myself. For the web Go fits quite nicely. Really loving my time working with this language.
Now, if i could somehow throw it into the mix at work and build something with it it would be quite fun.1
Need some advice here.
So hello everyone! I recently moved abroad for work, for the sake of the experience and the excitement of learning how developers in Latin America tackle specific problems. To my surprise, the dev team is actually composed solely of Europeans and Americans.
I work for a relatively new startup with an ambitious goal. I love the drive everyone has, but my major gripe is with my team lead. He's adverse to any change, and any and all proposals made to improve quality of throughput are shot down in flames. Our stack is a horrendous mess patched together with band-aids, nothing is documented, there are NO unit tests for our backend and the same goes for our frontend. The team has been working on a database/application migration for about a month now, which I find ridiculous because the entire situation could have been avoided by following very rudimentary DevOps practices (which I'm shunned for mentioning). I should also add that for whatever reason containerization and microservices are also taboo, which I find hillarious because of our currently convoluted setup with elastic beanstalk and the the constant complaints between our development environment and production environments differing too much.
I've been tasked with managing a Wordpress site for the past 3 weeks, hardly what I would consider exciting. I've written 6 pages in the past two weeks so our marketing team can move off of squarespace to save some money and allow us more control. Due to the shit show that is our "custom theme" I had to write these pages in a manner that completely disregard existing style rules by disabling them entirely on these pages. Now, ironically they would like to change the blog's base theme but this would invertedly cause other pages created before I arrived to simply not work, which means I would have to rewrite them.
Before I took the role of writing an entire theme from scratch and updating these existing pages to work adequately, I proposed moving to a headless wordpress setup. In which case we could share assets in a much more streamline manner between our application and wordpress site and unify our styles. I was shot down almost immediately. Due to a grave misunderstanding of how wordpress works, no one else on the team seems to understand just how easy it is to fetch data from wordpress's api.
In any event, I also had a tech meeting today with developers from partner companies and realized no one knew what the fuck they were talking about. The greater majority of these self proclaimed senior developers are actually considered junior developers in the United States. I actually recoiled at the thought that I may have made a great mistake leaving the United States to look a great tech gig.
I mean no disrespect to Latin America, or any European countries, I've met some really incredible developers from Russia, the Ukraine, Italy, etc. in the past and I'm certainly not trying to make any blanket statements. I just want to know what everyone thinks, if I should maybe move back to the states and header over to the bay/NY. I'm from the greater Boston area, where some really great stuff is going on but I guess I also wanted a change of scenery.2
Anyone experience with microservices?
I want to offload CPU intense workloads to another server while I use my main webserver for just simply serving files and I have a couple of questions... Like were to start researching if this idea is even viable
Thanks in advance!19
Jungla is an alternative to GraphQL with some unique features.
The goal of Jungla is to have the freedom to structure your results the way you truely want, on the fly.
Rather than defining your schemas before the requests like in GraphQL... Jungla can be entirely defined in your request, or implemented server side for quicker request times.
Come and take a look...10
So this manager told me we need to build accelerator. What's an accelerator. He told that it some how manages Microservices.2
So a while back I decided to overhaul my entire code base and rewrite everything in one application... yesterday I thought this was bad so have moved back to separate applications, just this time as microservices! Does anyone else do this without ever releasing the initial thing you set out to do?
University student here. I’m trying to learn how to build scalable applications. I figured what better way to learn, than to ask this community!
So, some questions:
1. What is a good stack for scalability
2. Regarding microservices, when and where should you use node, .net, and go
3. I hear much talk about docker and kubernetes... how would you use these concerning microservices
Just learned how to use Spring + Eureka + Feign + Ribbon to easily discover microservices as they're deployed, do basic load balancing, easily hitting endpoints on other micro services, etc.
Mind = blown 🤓
Time for an exam about Cloud computing and deploying Microservices to the cloud using kubernetes, followed by another exam about Usage of scientific C libraries. This feels both so disconnected for being part of the same degree.2
A very long rant.. but I'm looking to share some experiences, maybe a different perspective.. huge changes at the company.
So my company is starting our microservices journey (we have a 359 retail websites at this moment)
First question was: What to build first?
The first thing we had to do was to decide what we wanted to build as our first microservice. We went looking for a microservice that can be used read only, consumers could easily implement without overhauling production software and is isolated from other processes.
We’ve ended up with building a catalog service as our first microservice. That catalog service provides consumers of the microservice information of our catalog and its most essential information about items in the catalog.
By starting with building the catalog service the team could focus on building the microservice without any time pressure. The initial functionalities of the catalog service were being created to replace existing functionality which were working fine.
Because we choose such an isolated functionality we were able to introduce the new catalog service into production step by step. Instead of replacing the search functionality of the webshops using a big-bang approach, we choose A/B split testing to measure our changes and gradually increase the load of the microservice.
Next step: Choosing a datastore
The search engine that was in production when we started this project was making user of Solr. Due to the use of Lucene it was performing very well as a search engine, but from engineering perspective it lacked some functionalities. It came short if you wanted to run it in a cluster environment, configuring it was hard and not user friendly and last but not least, development of Solr seemed to be grinded to a halt.
Elasticsearch started entering the scene as a competitor for Solr and brought interesting features. Still using Lucene, which we were happy with, it was build with clustering in mind and being provided out of the box. Managing Elasticsearch was easy since there are REST APIs for configuration and as a fallback there are YAML configurations available.
We decided to use Elasticsearch since it provides us the strengths and capabilities of Lucene with the added joy of easy configuration, clustering and a lively community driving the project.
Even bigger challenge? Which programming language will we use
What we’ve noticed during researching various languages is that almost all actions done by the catalog service will boil down to the following paradigm:
- Execute a HTTP call to fetch some JSON
- Transform JSON to a desired output
- Respond with the transformed JSON
Actions that easily can be done in a parallel and asynchronous manner and mainly consists out of transforming JSON from the source to a desired output. The programming language used for the catalog service should hold strong qualifications for those kind of actions.
Another thing to notice is that some functionalities that will be built using the catalog service will result into a high level of concurrent requests. For example the type-ahead functionality will trigger several requests to the catalog service per usage of a user.
To us, PHP and .NET at that time weren’t sufficient enough to us for building the catalog service based on the requirements we’ve set. Eventually we’ve decided to use Node.js which is better suited for the things we are looking for as described earlier. Node.js provides a non-blocking I/O model and being event driven helps us developing a high performance microservice.
The beauty of microservices and the isolation it provides, is that you can choose the best tool for that particular microservice. Not all microservices will be developed using Node.js and Elasticsearch. All kinds of combinations might arise and this is what makes the microservices architecture so flexible.
Even when Node.js or Elasticsearch turns out to be a bad choice for the catalog service it is relatively easy to switch that choice for magic ‘X’ or component ‘Z’. By focussing on creating a solid API the components that are driving that API don’t matter that much. It should do what you ask of it and when it is lacking you just replace it.
Many more headaches to come later this year ;)3
This headhunter even took the time to bold out the hipster verbs like: blockchain, microservices, angular, react and vue keywords and hashtags ...
K thx bye
man, this nginx micro-services stuff is unreal - take your monolithic OOP application and split it across your environment and let them talk REST to each other. so sweet!6
I have nothing to do today. I could go Jack off in the bathroom for 3 hours, then go home and my boss would be proud of my hard work. He told me to leave him alone because he is busy today after I went back 10 time for more tasks. We don't use any issue tracker or anything, and I already commented all the code I have access to(microservices means it is all developed in small stand alone parts and I can only see mine. No repo....). But I get in chewed out if I seem unbusy!!!1
In this new World of Microservices Architecture, I fail to understand the monolithic application. My context being for interviews. They keep asking about the old ways. What patterns were used and security situation. How do you tackle that when I did not get a chance to work on old monoliths. But
I have been struggling with managing and keeping track of config secrets and keys. I know that keeping secrets in code is bad karma, but managing them with environment variables becomes cumbersome with multiple microservices running on multiple servers. To worsen this, add humans and access levels.
Whenever I Google, I feel like I am the only one who has this problem. Do you guys sometimes feel like this?
If you have any solutions, hacks or services that you use, please recommend.4

I'm planning on adopting Global Authentication and Authorization as a part of Microservices (described in the image below, propriety of: https://dzone.com/articles/...).
Anyone has a different opinion? What are your thoughts on this one?12
Today we finally launched Keycloak to secure our spring cloud microservice architecture!
Great feeling after 4 month of tailoring open source software, bug fixes and so much pain 😄
Anyone have books or blogs about microservices and APIs they like?
I spent so much time focusing on front end frameworks and technologies and now I'm having to teach myself RESTful API structures and micro service stuff. I should have spent more time on this earlier on...6
We're doing single login with Azure AD for a Java-based site. We need to also sync the user changes with a microservice.
Now, here comes the fun part: Microsoft is working on a new API which looks promising, which they recommend to use as they've migrated their resources there. But this new API has SDK for a ton of languages but Java, so that's a no-no. On the other side, the js sdk for the old API is borderline unusable and has no deltas (which we need to sync users), although the new one is pretty good.
As a cherry on the cake, applications created with the old API are not transferrable to the new one, but it is otherwise. This is detailed in a very small section of their labrythinc docs and I'm really hoping that this is true or we're thoroughly screwed.
Alas, Microsoft, you've disappointed me again!2
Remind me again why we have to use/support a weird entity creating framework across all microservices? So that every entity is consistent? (Who cares? Microservices shouldn't) Because hibernate is hard? (It isn't, and it's better documented than this, which needs hibernate anyway).
I'm just building a fragile distributed monolith.
Currently implementing a new feature for a client who lost their dev team. Long story. Groovy on Grails with node.js microservices. Interesting combination.
"Microservices" implemented on a PHP symfony/doctrine/rabbitMQ stack, whereby the app was daemonized. Lots of fun.1
In the year 2015 I graduated from a reputated university. Though I had a couple of offers from my campus Placements, I did not willing accepted those offer and tried updating my CV in job portals.
On the day June 25th 2015, I still remember I recieved a invitation to attend the interview with one of the reputated company and I was like very much excited to attend this interview.
1) I had coding round which lasted for an hour and half and the best part is I scored max marks 😉
2) next round was problem solving or algorithm round it was quite difficult, but somehow I managed to clear that too.
3) final round was managerial round which was very much tougher than these two, My manager was real technical guy who knew most difficult industrial problems. In fact I should thanks him because he thought me how to organise code while development and also he thought me corporate ethics as I was a fresher when I joined there.
4) so I cleared all the rounds and joined the company around 10 days after 25th.
5) my journey in this organisation was very good. I had learnt the tech stack and there I started working as a microservices developer.
Thanks to my previous organisation.
But dude it doesn't fall in my service's domain, you should be taking care of this.
What makes you think it lies under mine?
Then you start in a new job.. wow big scenarios, complex, hundreds of microservices, large architecture, tons of trainings... and you have a task to check one thing... and you ask, please i need the documentation about this feature. “We don’t have any document. You can track it manually vis debug”
Now I have 7 instances of Visual Studio attached with a lot of services with tons of breaking points looking where the breakpoint will hit
Can you provide good resource for microservices with yii2?
Are those related? Cause a client asked about this combination and as far as I could find it seems that they aren't.8
"It's just as easy to create a small REST microservice as there is for a small one-off script, so let's follow the design pattern of creating a REST service first."
I don't think my manager understands how different in complexity these two things are.1
A mix of both python 2 and python 3. 4 entry points (although, this was done for the sake of microservices).
All in 1 big monorepo. Hosting a site in mostly static form (i.e each page had it's own index.html with completely different headers and footers, no templates).
Is it actually required to write unit tests in microservices?
every time i write them it feels like im just redundantly copying a method...
Dont get me wrong, im not against testing, I am using test environments, integration tests and mocks, but unit test seem kinda redundant to me.5
Didn't know it feels so great to take the 4:30pm shuttle back home. I played with my 4 year old, had tea with my wife, tinkered around my personal project, watched a YouTube video on microservices, and to top it all dined together. If only I could do this everyday.
Our lead dev has convinced the board to move the new software suite forward into .Net Core 3. Much of his reasoning is sound, a mainstay of which is the cost and ease of hiring developers to actually make and maintain it.
We are going for a microservices architecture. Combined with Typescript for type safety as the code base gets bigger, I am not sure I can think of many real advantages to choosing .NET instead. It will benefit from its async I/O later too, as the plan is to build in API driven dynamic UI down the road.
He is a fierce man, and I am the junior. Wish me luck.7
I finally published my first medium article, It's on Sticky sessions for microservices.
It took so much of my time to piece everything together that I wrote a small how-to, so that my fellow devs should not suffer like I have.
A module for molecules, which take an OPEN API definition and creates a restful API and graph definitions.
So all the proxy database stuff on a rest API can be done easily inside a microservices architecture.3
Does Really Nodejs - js environment is the best environment in the world ? i mean why people create their RESTful API in js ? from singular to microservices ? does it really that scalable ?
do i have any alternative ? i can't stand anymore change working with js anymode :(32
I'm afraid of trying micro-services for the second time, spent my evening couping playing Far Cry 5 instead :/
(this time with go kit toolkit).3
I've been working for over a year now in this remote job as a sysadmin for a local client. I personally find this job quite intimidating at first with all of the infrastructure and all of its many microservices running in high availability set up. I enjoyed learning everything about them and why it's been set up this way, which gives me ideas if I were to build my own app (not competing with my current employer, of course).
But now I don't feel comfortable managing this beast in its many environments.
From time to time, I would hear from my old colleagues at my old sucky company for help in their work and that they know I'm an expert in. I help and it makes me feel good.
Now I'm at a career dilemma. I don't want to lose my current job because I feel "uncomfortable" with managing and administrating the tech holding the whole infrastructure. And I don't wanna go back to my old job with the sucky pay and the feel of being unchallenged. And if I try to find another job, I might be as lucky as I do now, especially good difficult it is for me to find a remote job to begin with.
Objectively, I just need to clear off my debts (at this rate, in 4 years), and have a side income to support my family. But I don't think I can follow through on that plan. Should I look for a new job or do better with the current job that I have now?3
I was looking for a book on Microservices Architecture. There are several books, but I need one which explains all the patterns and related styles on design. The reason being is, I'm convinced about Microservices, but I need to convince my fellow teams and managers.4
Nothing like constantly having to spend 3-5 days of spin up on trying to help another team with their microservices because they have such a severe lack of documentation that I can't just follow a readme to get their projects running. Instead, I have to bug one of their developers to help me get it up and running (because they use non-standard project setups and dependency management), delaying things even more. No matter how much I scream that we need documentation no one makes it a priority.
Did I mention these are microservices written in Golang and I'm a front end developer? And I'm being made to work on back end tasks because we have a crazy high attrition rate and they won't back fill the back end positions.3
Any suggestions for good reading regarding the boundaries of Microservices? By this I mean a domain driven design approach.
I have a pretty good idea of what I “think” is right for my project. But something is telling me to challenge my idea.
For a little bit of background... I am using separate DBs for each Microservices, and building APIs to access the information across the system.2
Question directed to devs who know a bit about setting up middle sized architecture.
Prestory: Joined into development of a middle sized online game. Figured they created a monolith over the last 6 years up to a point where nothing works properly and nothing can be changed without wrecking the whole system. Figured a monolithic approach isn't such a great idea.
Current Situation: In a different, same scale online game development team, game itself working but team is struggling with architecture.
My job is to come up with an approach on how to set up masterserver/matchmaking/database etc. Reading through various articles about common principles (SOLID etc.), i figured that a microservice+event-/servicebus architecture may work for that kind of project.
The idea would be to have a global interface in which microservices can be hooked. So a client registers to a client handler on startup, then starts to queue for a game, the client handler throws an event on the bus to register the user to matchmaking. The matchmaker happens to listen to those events (Observer Pattern) and adds him to matchmaking, when a match is found it throws an event on the bus to connect the user to the server, etc. One can easily imagine a banhandler throwing in a veto to cancel such an action, metrics and logging is fairly simple to add (just another service listening to all events), additionally Continuous Delivery, FRP and such are also beneficial advantages and it is said to scale well.
The question is, would you do the same, is there maybe something i might be overlooking? Do you have better ideas?
Keep in mind that we are not too experienced and are bound to different languages (python, C++ and java mostly) and are a small (4 Devs) Team with different strengths.
Thank you for your feedback and criticism!1
Does anybody know, how resilience could be achieved if any of your microservices is down. Please suggest me if any. I had one approach in mind but that doesn't seem to be efficient.3
Projecting and developing microservices architectures at big companies. Also I hope I'll be contributing the kernel a day
We have an API and a lot of microservices based on that API. Additionally we have a store of protobuf-templates (files to automate serializing certain events etc).
Currently for each service we have the API with general stuff (connection stuff etc) and then copy the 5 or 6 proto-files we need for that service, they update sometimes, so does the API, for each service, two things that need to stay updated. Which option would seem more logical to you?
a) Integrate all proto files into the API. The services then only need to update the API but they also have access to many proto files they don't need for that service (which are required for other services however)
b) Keep them seperated and keep manually updating the proto-files for affected services
Disclaimer: our proto files are always backwards compatible by design, both the API and protofiles change fairly frequently.
New guy in the block!. Just started with a new position in a new company too!.
Designated as as Devops Engineer (after my 2 years of experience as one) in a well funded Saas Startup!. Lots to learn. I used to work in Openstack Terraform puppet etc whilst here it's fully AWS. I was expecting this right from the start but woah.
Lambda, dynamodb, cloudformation, ssm, codebuild, codepipeline
Serverless framework, Flask and node mixed apps , Vue (including vuex) js Front end, graphQl api, and rest for between microservices.
Lots of ground to cover and I've not consumed this much topics before. Especially graphQl and Vue js are being a pain for now .
Each Devops engineer is working on a tools to improve the productivity and shorten the release time. Lots of automations in the pipeline!.
I'm not sure this qualifies as a rant but here you go!.2
After a year and a half of working with what i love (nodejs microservices and bit of python) I have to update my php skills and refresh my memory with latest Laravel 😕 (I used it as an authentication/authorisation and REST backend for a react native app early 2016 and did not touch it since)
Passive Job hunting sux and yes PHP ain't my thing anymore 😔 i mean i have next to 6-8 years exp in it but given the choice... 😒
I used to love it (so many good memory with cakephp 😌🙄it teached me a lot early in my carrer) before I discover functional programming paradigm and got deep understanding of JS
I just thought of an elegant solution to a problem in prod. Basically need to run 2 different versions of a app.
Just deploy it to uat and point it to prod db for the data.
I guess if we were following microservices architecture though we could deploy both versions to prod but we don't....3
I NEED HELP with Kafka
I'm working a thesis. I developed 4 different microservices (REST APIs). I would like to use Kafka to support large number of users. I may also place the microservices behind a HAPI Proxy. How can I use Kafka to stream requests and respond accordingly. I'm using Node.js. I think I haven't grasped Kafka. My Prof, suggested I try it to act as a broker but I'm blank right now. How do I tell Kafka I want it do a POST or GET etc?2
since we have go mod I believe that if you are doing microservices or fracturing a monolith app into microservices for that matter, you rather have a monorepo. I'm finding really useful to do `import ("backend/monolith" "backend/notify")` and such than sharing protobuf files by copying with some Makefile target.
So, in a microservice or web service pattern what is most important unitary test or functional test?
Just finished creating a new git repository for my modules (we're using microservices)
Guess what, i misconfigured the socketmaster and the apps port
So the socketmaster run on :9000 meanwhile my apps run on :8888
Spend a good 1 hour to find that problem
