What Is Etcd and How Do You Set Up an Etcd Cluster?
Etcd is an open-source distributed key-value store created by the CoreOS team, now managed by the Cloud Native Computing Foundation. It is pronounced “et-cee-dee”, making reference to distributing the Unix “/etc” directory, where most global configuration files live, across multiple machines. It serves as the backbone of many distributed systems, providing a reliable way for storing data across a cluster of servers.
