Is this compatible with AWS Lambdas on some level? Could it be? What about FastCGI/WSGI/... compatibility? I'm thinking it could be really nice for hobby projects and for developing on a laptop.
It's a hodgepodge of different services.

Since this is a POC it's probably not worth looking at or trying to use as the instructions are in bad shape.
Hobby projects or projects with low number of requests are ideally fits. And it could be run on very low-end devices: raspberr pi, cheapest VPS, etc..
