High Availability Cluster Software Overview

What is a High Availability Cluster?

A High Availability Cluster (or HA Cluster, also called failover clusters) are servers that have been grouped together so that if one server providing an applications fails, another server immediately restarts the application. In this way application reliability is maintained and down-time is minimized or nearly eliminated.

High Availability Cluster Software (or just High Availability Software) are the automated cluster management platforms designed to achieve constant application availability without intervention by a human operator.
