Is this even achievable with Lambda though? Even with Lambda, you still have to configure your "infrastructure", just that instead of ELB and EC2, you now have to manage APIGW and Lambda, and any other "wiring" that you need to put in to do what you needed.

All in all, I can't really say Lambda is really all that "easy" considering options like AWS EB/ECS can be setup relatively easily.
