Definitely there will be cases where it makes sense. But intuition would suggest if your servers are say 80% idle then serverless functions would be cheaper, but that isn't actually the case. Cloud companies don't incur much of a cost from a VPS either if it's idle.

My team noticed the same with AWS Aurora Serverless (a database), it was so expensive that it was easier to just run a normal instance of RDS.
