We will do a quick introduction to the Serverless world and AWS Lambda to establish a baseline for everyone. Then we'll jump into a Ruby Framework that makes Serverless easy to work with. Ruby is the not only one of most beautiful languages in the world but also extremely powerful. The power lies in Ruby's Metaprogramming abilities. This serverless framework leverages these Ruby powers to create a DSL that essentially translates Ruby code to AWS Lambda functions. We'll introduce these Framework concepts: * Controllers * Routes * Jobs We will create a few demos and deploy it to AWS Lambda live. We will also cover some architecture pattern examples that can be built with the framework.
