Farewell to the Era of Cheap EC2 Spot Instances
EDIT: if you really need GPU compute power, go buy a GPU from the computer store around the corner - they are cheap, fast and available.I gave up on ec2 when they started requiring you "request for quota" to start a gpu instance.You have to "request for quota" even if you want to run a single instance.You have to specify which specific instance type you want.You have to specify which region you want it in.Then you sit back and wait for some human to "approve your request".In my case this took 24 hours.In this time I literally could have walked (not driven) down to the local computer store, bought a computer, pushed it back to my house in a shopping cart, spent a few hours configuring it and still be left with 16 hours to have a sleep, eat and do some other things.AWS quota system is so far from "scalable" and "elastic" that it's effectively useless.  You can't design any sort of infrastructure around that sort of quota system.I dumped AWS at that point.  Mind you, Azure has exactly the same quota system.Seriously, just rent a server from Ionos or Hetzner or get a fast Internet connection and self host.  It's faster and better and cheaper than any of the big clouds.
