My only “yes, but…” is that this:
> 50k API calls per second (on S3 that is $20-$250 _per second_ on API calls!).
kind of smells like abuse of S3. Without knowing the use case, maybe a different AWS service is a better answer?
Not advocating for AWS, just saying that maybe this is the wrong comparison.
Though I do want to learn about Hetzner.
