Hi, thanks for the interesting article. We too are happy with this new functionality. Previously this would require setting up the API Gateway, which was quite complicated.
Nevertheless, I believe that it is a must, to mention the security / cost implications of exposing a lambda function over the HTTP(S). Ignoring this could result in real trouble for those of us who don't have much experience yet with the cloud.
Any lambda endpoint available from the outside world MUST be secured and never available unauthenticated calls, unless one has a multi-million budget to spend. Every call to the lambda will be billed, simple as that. If the word gets out that there's an unsecured lambda endpoint available, brace for the worst. Your monthly bill might come as a shock.
Also, beware of the trap set up by Amazon. In the documentation they mention that you don't have to use the IAM security and instead use your own means of authentication. What they FORGET to mention, is that even if your custom auth code rejects the call with HTTP 401 Unauthorized, they will still charge you IN FULL, for all the incoming calls and resources used.
