So here I am in iceland watching Aurora with my gf, and suddenly I realized somewhere in my code at work I freaking forgot to add 1 to the denominator of a fraction. Shitty shit shit, gonna go back to work finding NaNs everywhere. Fuck fuck fuck

Oh my god, look at this beauty. Looks like aurora borealis. Too bad this setup wasn’t successful and is already lost.

Client: *uses Oracle on AWS RDS*

Ora: *licence about to expire*

Client: we need a cheaper and equally performant solution.

AWS: we have an outstanding Aurora db! Its performance is flawless!

Client: shut_up_and_take_my_money.png

Engineers: *migrating to Aurora mysql*
Engineers: fine-tuning the db for 2 months, adapting app code.
Aurora: *shits its pants during test ramp-up, delivers ~70% of Ora perf*

==========

Client: we need to do better!

AWS: try Aurora Postgresql!

Engineers: *migrating to Aurora postgresql*
Engineers: fine-tuning the db for 1 month.
Aurora: *shits its pants during test ramp-up, delivers ~40% of Ora perf*

AWS: let me see...
AWS DBAs: *fine-tuning the db for another 2 months*
Aurora: *survives ramp-up, delivers ~70% Ora perf*

AWS DBAs: your application is wrong.
We: Ora didn't complain about that...

AWS DBAs: umm.. Err.. Then your load test is wrong
We: ora wasn't complaining about that either...

AWS DBAs: errr.. Ummm.. Oh, I've got it! Your queries aren't optimized!
We: we cannot change queried - they are hardcoded by our framework's vendor

AWS DBAs: well there you go! Your queries aren't optimized! It's your fault, not aurora's

yyeeahhhh... Riight...

From my xp, aws support and aws engineers ALWAYS try to put the blame on a client. Always. Even when they're obviously wrong.

I wonder how many bitflips did they trigger last night...

Looks pretty. But much too scarry when you understand what it is.

My first Alienware PC. Aurora R7. Feeling amazing. New to pc games. Hoping to get Forza. I have a Ps4 and a xbox one too. But I like to get into PC gaming. Please excuse the cable mess. Still working on it.

One of the largest companies on the continent. Uses Oracle on AWS RDS with the beefiest resources available. It comes to the point where lowering the number of CPUs boosts the DB performance up (concurrency). Point is - Oracle is sweating hard during our tests. You can almost feel the smell of those hot ICs on AWS servers.

And then someone at higher levels, while sitting on a pooper, has a great idea: "I know! Let's migrate to Aurora! They say it's so much faster than anything there is!"

*migration starts*

Tests after migration: the database on the largest instance possible shits itself at 10% of the previous load: the CPU% is maxed out (sy:60%,us:40%), IO is far, far from hitting the limits.

Is it really possible Aurora will cope with the load better than Oracle? Frankly, I haven't seen any database perform better than Oracle yet. Not sure if it's worth to invest time in this adventure..

Amazon Web Services has the worst naming among clouds.

They have "Aurora" and "Athena". Both services relate to data. Both are woman's names. Both start with "A".

Amazon, what's wrong with you?

Amazon what the hell.
You provide a cool RDS proxy which can be used to manage connection pooling which is especially useful for concurrent Lambda invocations.
But if you have an Aurora cluster and a read-intensive workload it is basically useless because it only sends traffic to the writer instance.
WTF?! Literally the one use case we have is the one thing it doesn’t do. AAARRRGGHHHH

Looking for a teammate for AWS aurora database challenge
