About etcd

etcd is a database which is predominantly used in configuration management. It is distributed between multiple nodes and applies the RAFT consensus algorithm to ensure consistency. This consistency makes it an ideal source of truth for large deployments which need to observe configuration changes so that tools can act on them. The name comes from the idea of distributing the Unix "/etc" directory, where many configuration files live, across multiple machines – /etc-distributed.
