Hi! AFAIK in Zappa you don't define infra in Python but rather in json. Also the vision of Stelvio is broader than just serverless. I wrote about my vision here https://blog.stelvio.dev/why-i-am-building-stelvio/ if you're interested.

The cloud is too complex.

While it's good to enable proprietary solutions like AWS, we should always make sure what we make is not bound to it.

This might mean that stelvio becomes a part of something more general.
