I’ve seen multimillion dollar “enterprise” projects get no where close to that. Of course, they all run on scalable, cloud native infrastructure costing at least a few grand a month.

> a few grand a month.

A negligible cost for a successful tech business that also works when your requirements exceed the capabilities of a single VPS.

I agree. But these are projects that barely get any requests.

I think the better question to ask is what services peak at a few hundred transactions per second?
