Here's the presentation I gave at the AWS Summit in Toronto 2018. Abstract: In this dev chat, we review how to run Ruby on AWS Lambda using a tool called Jets. Jets is a framework that enables you to create serverless applications with the beautiful language, Ruby. Learn how Ruby support was added to Lambda with native-like performance, and discover how Lambda works under the hood to understand how this was accomplished. We show you how to get started through a demo with a Lambda Ruby application, and we deploy it to Lambda with a single command.
