Explore the fundamentals of etcd, a powerful tool for distributed locking and service discovery, in this 42-minute conference talk from Strange Loop. Delve into the underlying consensus algorithm and code architecture that powers etcd's accessible HTTP+JSON API. Discover how etcd's primitives, inspired by Google's Chubby and Apache Zookeeper, can be leveraged in your projects. Learn about the extensive libraries and tools developed by the etcd community, and gain insights into the open-source project available on GitHub. Presented by Brandon Philips from CoreOS, this talk offers valuable knowledge for developers working on modern Linux server infrastructure and distributed systems.
