Abstract: A non-transitory computer-readable storage medium storing therein a proxy response program that causes a computer to execute a process includes requesting suspension or pausing of a virtual machine when an idle state of the virtual machine is detected, changing, when the virtual machine is suspended or paused, settings information of a communication control device between a terminal device and the virtual machine, so as to transfer access from the terminal device to the virtual machine, to the computer; sending, when the access to the virtual machine that is suspended or paused is transferred, a response to the terminal device on the basis of communication response settings information relating to a communication response to the terminal device by the virtual machine that is suspended or paused; and requesting resumption of the virtual machine that is suspended or paused in response to the transfer of the access.

Abstract: A non-transitory computer-readable storage medium storing an activation control program that causes a computer to execute a process, the process including specifying a time until a specific access to each of a plurality of virtual machines has been detected after an activation of each of the plurality of virtual machines based on pieces of activation history data of the plurality of virtual machines, determining activation order for the plurality of virtual machines based on the specified times, and activating the plurality of virtual machines in accordance with the determined activation order.
