Group communication system for implementing High Availability in applications

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 extended 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.
