I'm also very curious which direction things will move. I think I'm less convinced than you are that it'll be away from AWS and the like though, they're innovating at least as fast as the open-source container cluster tools (at least it seems that way to me).
I can imagine a future where it gets easier and more common to build an arbitrarily complex backend by just hooking together AWS services, using Lambda (or something that evolves from it) to write all your custom business logic without ever thinking about a server, VM, or container. I'm working on a greenfield app and very seriously considered this route now we but ended up deciding the uncertainty vs doing it the way we know wasn't quite worth it. It feels very close to the tipping point to me though.

you're risking to awaken the ghost of Application Server.

Either way it's definitely an exciting time
