My experience with servless is that while this may be true at a certain level:
> No server management
I feel like in Amazon's current toolset, you are MORE aware of "servers" than you ever have been before. It's just abstracted into a different layer (cloudformations, etc). The boilerplate for severless projects it's a complete mess, imo.
Besides that, the Develop/Test/Deploy/Manage lifecycle is really difficult to reason about. I would hate to be the one on call when a serverless service goes down and I have to figure out what's going on!
I look forward to Amazon releasing more tools (or cleaning up the ones they have) to make Serverless a breeze to work in.
