Lambda is awesome .. until you actually try to use it for realsies. Cat turd is an apt description. Just being able to get the damn logs for debugging is itself a hassle. Terraform helps a ton in all this and I rarely find myself using the AWS UI anymore. Still Lambda is a great idea that just doesn't deliver for any use case more than responding to some S3 upload action or Event Bridge operation.
Don't even get me started on the API Gateway sitting in front of a group of related Lambdas. Its OK once you get it setup and running but buildign/changing it amounts to stabbing yourself in the eyes.

I saw you post "lambda is awesome" and was going to reply with "only in certain circumstances." But you beat me to it.
After about a year of poking lambda to see how it actually worked (versus how it was documented) and building a cloud formation replacement (TF eventually did what I wanted, but not before I made a simple PROLOG based replacement for it). But I finally made it work after MUCH struggle.
So... +1.
I put this in our code several years ago: "WARNING: Do not look at Lambda stack with remaining eye."
