etcd

etcd is a high-availability key-value store for Linux. It is designed for distributed applications that need a shared place to keep small but important pieces of data. The product is particularly relevant to developers and operators working with clustered or networked systems.

etcd uses the RAFT algorithm to manage failover within an etcd cluster. This allows the cluster to continue handling the key-value data when failover conditions occur. Its role is to provide shared data storage for components that operate across multiple parts of a distributed application. The stored information is intended to be compact and important to the application’s operation.

etcd is well known in the Docker community, where it can serve as a shared store for distributed application data. Its Networking classification reflects its use in coordinating data between connected application components. The Linux platform designation makes it suitable for users seeking this type of service on Linux systems.

etcd is available under a free license. MirrorNest links directly to the official etcd release instead of hosting a mirrored copy, giving users a catalog entry that points to the original distribution.
