A cluster-aware application is a software application designed to call cluster APIs in order to determine its running state, in case a manual failover is triggered between cluster nodes for planned technical maintenance, or an automatic failover is required, if a computing cluster node encounters hardware or software failure, to maintain business continuity. A cluster-aware application may be capable of failing over LAN or WAN.^[1]^[2] ^[3]

Cluster-aware application characteristics

edit

Use TCP/IP to maintain heartbeat between nodes.
Capable of transaction processing.
Mirroring cluster information in realtime.
