etcd on Compose
etcd puts the “distributed” in distributed server configuration management. This key/value store holds the always-correct data you need to coordinate and manage your server cluster.
Compose provides automatic backups of your configuration data stored in etcd and an intuitive administrative interface that lets you monitor, scale, and administer your deployment with ease.
The Source of Truth
etcd uses the RAFT consensus algorithm to assure data consistency in your cluster and also enforces the order in which operations take place in the data so that every node in the cluster arrives at the same result in the same way. This is how etcd ensures the server cluster state is the source of truth. Additionally, features like atomic CAS and CAD commands (which keep keys and values from being inadvertently overwritten or deleted) and the ability to wait and watch for changes to keys and values (which means your applications can stay up-to-date) provide the rigor you require for your configuration data and the applications that rely on it.
And you can rest easy when it comes to the security of your deployment. We provide features such as private VLAN, IP whitelisting and SSL. In addition, our web-based administration console offers 2-factor authentication and user management for your etcd deployment.
