Abstract
The present disclosure is to more reliably determine whether an active-system server appropriately provides a service to a client. A cluster system (1) includes an active-system server (2) that provides a predetermined service to a client device through a network (4) and a standby-system server (3) that provides the predetermined service to the client device in place of the active-system server (2) when an abnormality occurs in the active-system server (2). The standby-system server (3) includes a monitoring unit (6) that accesses the predetermined service provided by the active-system server (2) through the network (4) to monitor whether the predetermined service is normally accessible. The active-system server (2) includes a cluster controlling unit (5) that performs a failover when the monitoring unit (6) of the standby-system server (3) determines that the predetermined service provided by the active-system server (2) is not normally accessible.
