Active Passive cluster consists of two nodes: active node and passive node. Active passive cluster ensures constant service of a certain application keeping redundant nodes to back up system in the event of a failure. When the active node goes down one of the backup nodes takes the responsibility and runs those services. In the process of fail over, the services are restarting on another node immediately without administration intervention.
