Abstract: A system-replication control apparatus includes a processor that executes a process. The process includes: monitoring a use state of a resource in each of data centers; storing facility information indicating resources respectively held by the data centers and a use cost of the resources, and replication condition applied when each system is replicated in a resource of another data center; and selecting a resource composition that satisfies the replication condition and that costs lower than a currently-selected resource, as a replication destination of the system, from among available resources by referring to the use state of the resource obtained at the monitoring and the facility information.

Abstract: An application management device includes a memory that stores therein application conditions for defining a condition of whether an update program is to be applied to a data center. The application management device acquires information for an update program from a control center that manages failures in a plurality of data centers including the data center. Thereafter, the application management device controls the application of the update program to the data center based on the acquired information for the update program and the stored application conditions.

Abstract: A control server includes a memory that stores therein configuration information on a system that operates in each of data centers. The control server specifies, from the information stored in the memory, a data center having configuration information on the system that meets a condition under which a failure occurs. Thereafter, the control server transmits failure information relating to the failure to a notification destination of the specified data center that meets the condition under which a failure occurs.

Abstract: A failure monitoring device includes a selecting unit and a migration control unit. The selecting unit selects, when a failure related to software occurs in a system that is operated in one of data centers that are arranged in geographically separate locations and that can communicate with each other, an engineer who handles the failure. The migration control unit migrates, when an engineer belonging to another data center that is different from the data center in which the system is operated is selected by the selecting unit, the system to the another data center.
