Recorded at SpringOne Platform 2016.

Leader election allows applications to work together with other applications to coordinate a cluster leadership via a third party system. A leader can then be used to provide global state or global ordering, generally without sacrificing availability. In this presentation, we show how Spring Cloud Cluster provides a simple abstraction for leader election and how it is implemented using ZooKeeper, Hazelcast, and etcd.
Note that the 1.0.1 release deprecates everything in favor of code that now lives in Spring Integration.
