Alexander Wood (Amazon Web Services) live-codes a serverless web application, including asynchronous events, on AWS Lambda using the Ruby runtime. Using open source tools such as the AWS SAM CLI, the AWS SDK for Ruby, and the Aws::Record Ruby gem, Alexander goes from a blank folder to a web application that has high availability and can scale to thousands of requests per second.

Prerequisite knowledge

• Experience writing production web applications of any kind (useful but not required)

What you'll learn

• Learn how to develop serverless web applications in a live-coding format, the set of open source tools available both generally and for Ruby serverless functions, and a number of best practices for serverless development

This session was recorded at the 2019 O'Reilly Open Source Software conference in Portland.
