Don't want to hijack the thread (sorry) but I've been working for the last 10 months in a tool which might be of the interest of people reading this article.

This tool will be opensource in the following weeks, but at the moment is in closed beta. I'm looking for people interested in giving it a look. If you are interested, drop me an email to me[at]jorgebastida.com and I'll invite you to the repo.

tl;dr version: Dead simple Lambda+Kinesis+Dynamodb+S3+CloudWatch+Apigateway over Cloudformation with support for Python, Javascript, Java, Go etc... Lot's of examples including Telegram, Twilio, Slack... and quite extensive documentation (which I think is the key of adoption of a technology like this).
