A high-availability (HA) architecture in which a backup server application remains initialized, with clients connected to both the primary and the backup servers at startup. In this redundancy type, the primary server always synchronizes its state with the backup. Data synchronization and existing client connections to the backup ensure higher service availability. In Enterprise Routing Solution, Hot Standby redundancy type is available at the High Availability Routing level.
