We use Lambda for 100% of our APIs some of which get over 100,000 calls per day. The system is fantastic for micro services and web apps. One caveat, you must use a framework like Serverless or Zappa. Simply setting up API Gateway right is a hideous task and giving your function the right access level isn’t any fun either. Since the frameworks do all that for you it really makes life easier.

One thing to note. API Gateway is super picky about your response. When you first get started you may have a Lambda that runs your test just fine but fails on deployment. Make sure you troubleshoot your response rather than diving into your code.

I saw some people complaining about using an archaic version of Node. This is no longer true. Lambdas support Node V6 which, while not bang up to date, is an excellent version.

Anyway, I can attest it is production ready and at least in our usage an order of magnitude cheaper.
