Great high level doc on Lambda.

Personally, I love this service. My most critical personal software runs on Lambda. It's insanely cheap and easy to deploy (with Serverless.io, though i would like to move to Open tofu at some point).

Testing is difficult if you rely on Lambda's out of the box runtimes. I recommend using Docker images with the Lambda RIC built in. Way easier to test (with the Lambda RIE) and tons more flexibility.

If you use your own Docker images, you lose one of the main benefits of Lambda, which is that AWS will take care of automatically patching all the security vulnerabilities in the infrastructure platform. My goal is always to outsource as much of the code as possible to AWS, and implement myself as little as possible.
