Description

The Corosync Cluster Engine is a Group Communication System with additional features for implementing high availability within applications. The project provides four C Application Programming Interface features:

* A closed process group communication model with virtual synchrony guarantees for creating replicated state machines. * A simple availability manager that restarts the application process when it has failed. * A configuration and statistics in-memory database that provide the ability to set, retrieve, and receive change notifications of information. * A quorum system that notifies applications when quorum is achieved or lost.

Corosync is used as a High Availability framework by projects such as Apache Qpid and Pacemaker.
