In computing and related technologies such as networking, failover is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application,1 server, system, hardware component, or network.
Failover is a means of achieving high availability (HA). Think of HA as a feature and failover as one possible implementation of that feature. Failover is not always the only consideration when achieving HA.
There are two complementary patterns to support high availability: fail-over and replication.
