etcd: A Cornerstone of Distributed Systems For Containers

etcd is an open source distributed consistent key-value store that was introduced by the team at CoreOS. Since its release two years ago it has become a mature cornerstone of a variety of systems in the container ecosystem for doing networking, service discovery, configuration management and load balancing. This talk will explore what etcd is, how it works, why it is used, how a cluster is maintained and some best practices. It will show off some example applications built on etcd such as locksmith, vulcand, Kubernetes, skydns and confd.
