Abstract

A CPU is allocated in view of service requirements of a virtual machine. An IaaS platform generates a virtual CPU and a virtual machine on a physical CPU of a compute node and allocates the virtual CPU to the virtual machine. This IaaS platform includes a resource allocation determination unit 32 configured to generate an instruction to cause the virtual CPU allocated to the virtual machine to occupy a physical CPU of a designated compute node in a case where load to be imposed on a process which is to run on the virtual machine is higher than a predetermined value, and generate an instruction to pin the virtual CPU at the physical CPU in a case where latency requirements of the process are stricter than a predetermined value, and generate an instruction not to pin the virtual CPU at the physical CPU in a case where the latency requirements of the process are laxer than a predetermined value, and a virtual machine generation management unit 34 configured to generate a new virtual machine on the physical CPU of the compute node in response to the instruction from the resource allocation determination unit.
