I am currently working on a project attempting to achieve something like this called Valar (https://valar.dev). It's still quite experimental and in private beta, but feel free to take a look and put yourself on the waiting list. I'm targeting small, private projects so it's not really suited for full-on production workloads yet.

The core of it is a serverless system that shrinks workload quotas while running them (similar to the Google Autopilot system). This way you don't have to rewrite your entire codebase into lambdas and the end user can save a lot of costs by only specifying a resource cap (but probably using a lot less, therefore paying less).
