Tech Stack: GitHub is a Rails 4 application that is composed of a large monolith and a constellation of services written in Ruby, Go, and a handful of other languages.  The app and its services are exposed both internally and externally via a GraphQL API.  We primarily rely on MySQL for persistent storage, Redis for temporary storage, and, as you might expect, a lot of git repositories.  We rely on Kubernetes for container orchestration.
