Thanks. That's exactly the kind of answer I'd hope I would get. Precise and actionable.
Admittedly, I'm a fan of serverless. I believe serverless will soon become a dominant form of cloud computing. I think it is just a matter of immaturity of the platforms and lack of tools. While I can't do much about the platforms, I can try to build better tools.
That's what my team and I are doing with Mantil https://github.com/mantil-io/mantil
