Search - "microservices"
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
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.."
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?? *3
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"16
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
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.
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
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.15
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 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 it15
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 problen17

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 sense12
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
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
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
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.4
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.7
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
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
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
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
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 ^^19
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
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
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 udemy4
Building a new project
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
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
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
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
Build this as a monolith, microservices are to complicated..
Said no and did the docs first, to make it look easy. Problem solved ;)
Microservices! So many little services and parts communicating and working together and everything going to shit on my first 100 tries, love it.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
Unrecruited recruiter email: “(...) The backend consists of 6 microservices (...)”
No. The backend consists of 6 macro-services.
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
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 planning2
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. :^)
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.1
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

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
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.
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
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
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
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
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
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
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!
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.
So this manager told me we need to build accelerator. What's an accelerator. He told that it some how manages Microservices.2
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
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 🤓
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.
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
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
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
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
Another team doesn't have time to add a batch endpoint to their service... Instead of having our team add it and submit a PR management wants a whole new microservice with one endpoint that queries the other services database directly.
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
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 😄
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.
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
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.
"Microservices" implemented on a PHP symfony/doctrine/rabbitMQ stack, whereby the app was daemonized. Lots of fun.1
Currently implementing a new feature for a client who lost their dev team. Long story. Groovy on Grails with node.js microservices. Interesting combination.
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?
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).
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
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.
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
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
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
Projecting and developing microservices architectures at big companies. Also I hope I'll be contributing the kernel a day
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
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 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
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
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
So, in a microservice or web service pattern what is most important unitary test or functional test?
