Ask HN: Skeptical about my company going “full serverless”. What am I missing?

I just started working with Lambda, so my experience may just be the teething pains, but. I find the developer experience a bit jarring. My lambda is in python, but every time I want to test my code I have to "build" the lambda with the `sam build` tool and only then can I exercise it. It takes a non-trivial amount of time to build.

The deployment story looks good though, with the `sam deploy`, but for now I can't get over the developer experience.

My recommendation is to invest in testing now while it’s easy. You can mock the incoming events and use something like moto for service mocks. That catches dumb mistakes sooner.

Also, don’t put any logic in the handler itself unless it’s extremely trivial.

Sound advice, but that ship has sailed. This is an existing lambda that I'm refactoring so I need to be able to "go through the front door", as it were. Once I become more familiar with the code, I'll be able to test individual pieces are you're recommending.
