Active Passive Clusters

An active-passive cluster is a high availability architecture in which one node is active (processing requests) and one or more nodes are passive (standby). If the active node fails, one of the passive nodes is automatically promoted to become the active node. This ensures that there is always a single active node in the cluster, which simplifies management and eliminates the need for complex failover procedures.
