Abstract: A first computer server included in a cluster system includes a plurality of network interfaces, a memory, and a processor coupled to the memory. The processor retrieves a first Internet Protocol (IP) address and a second IP address from the memory. The processor initiates a first communication process with a second computer server included in the cluster system via a first network interface of the plurality of network interfaces. The processor sets the first IP address to the first network interface when the first communication process enables communication with the second computer server. The processor initiates, using the first IP address, a second communication process with a first device having the second IP address via the first network interface. The processor obtains a type of the first device and outputs information on the type of the first device in association with information on the first network interface.

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.
