etcd is a distributed reliable key-value store for the most critical data of a distributed system.
etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure, even in the leader node.
It uses the Raft consensus algorithm to manage a highly-available replicated log.
This is free and open source software.
