This is categorically false. If you have large capacity needs talk to your TAMs/...

It's been true five times in the last three years for me. The elasticity isn't always there and service limits are not always granted when needed.

I don't know what an AWS TAM is but the SAs have tried and failed.

Make a new account and try to run 1000 c4.4xl in parallel for 1 hour. It won't happen.

That's not what happened the five times, but it's illustrative.

And who defines what is a need and what is a want?

That's because of a history of bitcoin mining abuse. People post their API keys on github every day and Amazon refunds almost all of the lost compute time.

I've asked and got basically a "no". I can believe that if you have a history of spending big $$$ on AWS they get increasingly flexible with raising the limits. But if you don't, they aren't going to let you spin up 500 instances, even if you ask nicely and have a reasonable justification.
