Oh, I know it exists, and I know tons of people are using it.

But like I said, I don't think that the tooling is there right now for mass migration (or anything like it). It's really difficult to test/debug. It's difficult to dianose issues. It's difficult to even set up a "Hello World" API Gateway that uses lambdas. It's painful... as are all new technoligies.

I guess what I mean to say is: I look forward when I just jump on AWS and start using it for a production app, and the boilerplate and amount of config files I have to maintain drops.

I'm also aware of the tool called "serverless" ( https://serverless.com/ ) which is also a step in the right direction.
