We're hoping to write a case study down the road that will give more detail. But the short version is that not all parts of the client's organisation have aligned skills/incentives. So sometimes code is deployed that makes, shall we say, 'atypical use' of the resources available.

In those cases, it is great to a) not get a shocking bill, and b) be able to somewhat support this atypical use until it can be remedied.

Thank you for the reply

I'm honestly quite interested to learn more about the usecase that required those 50k API calls!

I've seen a few cases of using S3 for things it was never intended for, but nothing close to this scale
