High-Availability cluster aka Failover-cluster (active-passive cluster) is one of the most widely used cluster types in the production environment. This type of cluster provides you the continued availability of services even one of the cluster nodes fails. If the server running application has failed for some reason (hardware failure), cluster software (pacemaker) will restart the application on another node.

A high availability cluster is a group of hosts that act like a single system and provide continuous uptime . High availability clusters are often used for load balancing, backup and failover purposes.

High availability (HA) is a characteristic of a system which aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period. Modernization has resulted in an increased reliance on these systems.

Simply deploying a high availability architecture is not a guarantee of actually delivering HA. In fact, a poorly implemented and maintained shared-nothing cluster could easily deliver lower levels of availability than a simple data replication solution. A high availability (HA) deployment of two Citrix ADC appliances can provide uninterrupted operation in any transaction. With one appliance configured as the primary node and the other as the secondary node, the primary node accepts connections and manages servers while the secondary node monitors the primary.
