  • Publication number: 20170286259
    Abstract: A command transmission unit transmits a command input from a terminal device to an operational environment VM and a verification VM, which is generated such that configuration change is added to a configuration of the operational environment VM, and causes the operational environment VM and the verification VM to execute the command. A result acquisition unit acquires an operation-side output by the operational environment VM and a verification-side output by the verification VM for the command transmitted by the command transmission unit. A result transmission unit transmits the operation-side output acquired by the result acquisition unit to the terminal device. A determination unit determines success or failure of the configuration change on the basis of the operation-side output and the verification-side output acquired by the result acquisition unit.

  • Publication number: 20170269868
    Abstract: A cache holds, until a predetermined condition is satisfied, read data which is read, on the basis of a read request, from a storage device which has data including migration target data. A storage unit stores therein migration information which includes identification information and access date and time of the migration target data. A reading unit reads, on the basis of the migration information, the migration target data from the storage device in chronological order of the last access date and time and stores the migration target data in an area in the cache other than an area in which the migration target data has already been stored. A writing unit writes the migration target data stored in the cache to a storage device.

  • Publication number: 20170063622
    Abstract: An information processing apparatus includes a memory and a processor. The processor is coupled to the memory. The processor acquires information on the safety of locations where multiple data centers are placed through a network. The multiple data centers are able to communicate with one another. The processor calculates scores respectively indicating the safety of the multiple data centers on the basis of the acquired information. The processor further determines whether to move virtual machines built on each of the multiple data centers on the basis of the scores.
