We had a project almost 2 years ago where we needed to run g3.8xlarge instances on AWS in "serverless" mode to process videos using photogrammetry in real time. Going to AWS offices and asking for the solution resulted in "well, seems like you need Lambdas-on-steroids. We won't provide that service but feel free to build it by yourself".

So we built it and the moment we ran the crash test (we tried to go up to 1000 simultanious instances), it turned out eu-west-2 had just 48 instances available. We followed up and AWS confirmed that we just capped their region capacity for those instances. They didn't raise any quotas and suggested we use other regions to bypass the cap.

AWS always suggests you use a variety of instance types/availability zones to fulfill your capacity needs.

I can imagine they don’t keep a few thousand really expensive instances around (in every region/availability zone).
