Serverless Ruby!

A Serverless Framework example using an AWS lambda which runs a Ruby function. Inspired by serverless-php.

This project demonstrates a few cool technlogies. Foremost is the amazing AWS Lambda. It’s pretty exciting to see serverless architectures gaining adoption! Adding to the fun we have serverless, a framework for packaging and deploying across different providers including AWS, Google, and IBM. Also worth mentioning is the inclusion of Ruby. AWS Lambda supports a number of different languages natively, but Ruby is not one of them. Therefore we specially bundle the Ruby interpreter (courtesy of Traveling Ruby) and wrap it in a Node.js script which executes it as a binary.
