One of the huge bottlenecks associated with distributed systems is ensuring the configuration information (database connection details, cache settings, etc.) reaches safely and consistently across all machines in a system. It is in such scenarios that etcd could fit in. etcd from CoreOS is a highly-available key-value store for shared configuration and service discovery.
