Abstract:
1. An migration method of a virtual machine and a storage region on a plurality of computers coupled to each other through a relay device, each of the plurality of computers includes a processor and a memory device, the method comprising counting a first number of requests received by the virtual machine in a certain period, the virtual machine executing data processing in response to the requests; counting a second number of accesses to the storage region by the virtual machine in a certain period; calculating a first value by dividing the first number by the second number; selecting a first processor among the processors included in the plurality of computers, and selecting a second memory device among the memory devices included in the plurality of computers; when assuming that the virtual machine is to be assigned to the first processor and the storage region is to be assigned to the first memory device respectively, based on the first value, calculating a first response time of the virtual machine for at least one of the requests; and based on the first response time, determining whether to execute a migration of the virtual machine and the storage region to the first processor and to the first memory device respectively.
