AWS Lambda supports nodejs and jvm-based languages (Java, Scala, Clojure, etc.) directly, and lets you run Python, shell scripts, and arbitrary executables as well. We started with nodejs because it worked nicely for expressing our initial launch scenario, event handlers.

yes - I am aware that you support Python, etc. .. but nodejs is your first class language. For example, even your docs only mention nodejs (and java recently) [1]

what is even more interesting is that you felt it worked nicely for expressing event handlers. Can you talk a bit more about that - very interesting to see why not something like python or ruby. I know that nodejs is a callback-oriented framework... was it the fact that you can test locally on nodejs consistently versus what would be the expected output on Lambda ?
