Patrick Reynolds, Senior Systems Engineer, GitHub GitHub hosts tens of millions of repositories on hundreds of file servers. The Git Infrastructure team runs Git as a distributed service, providing highly available and durable access to repositories, despite frequent hardware and software failures. One key part of the service is Spokes, a self-healing replication, routing, and load-balancing layer built on top of Git. In this talk by Patrick Reynolds, a Senior Systems Engineer at GitHub, he'll discuss how Spokes detects failures and routes around them to provide high availability. Hear about how Spokes uses real-time replication and voting to durably store repository content. Watch as we induce failures and, ideally, no one notices.
