Method and apparatus for determining allocation design of virtual machines

An allocation design method, comprising:

• receiving, by using a computer, a request to allocate one or plural virtual machines for a system that includes the one or plural virtual machines to one or plural physical machines;
• selecting, by using the computer, first data concerning one or plural evaluation indicators for a requesting source user of the request among data that is concerned with one or plural evaluation indicators for virtual machine allocation and is registered in advance for each of a plurality of users;
• first calculating, by using the computer and for each virtual machine of the one or plural virtual machines, a first cost in case where the virtual machine is allocated to any one of usable physical machines of the one or plural physical machines, based on the selected first data to identify, for each virtual machine of the one or plural virtual machines, a physical machine for which the calculated first cost is the least among the one or plural physical machines;
• generating, by using the computer, allocation design data including second data concerning the physical machine identified for each virtual machine of the one or plural virtual machines;
• and
• allocating the one or plural virtual machines according to the generated allocation design data, wherein
• the first calculating comprises
• for each virtual machine of the one or plural virtual machines,
• calculating a second cost for each of the usable physical machines of the one or plural physical machines for each of evaluation indicators included in the first data;
• and
• calculating, for each of the usable physical machines of the one or plural physical machines, the first cost by adding the second cost calculated for each evaluation indicator of the evaluation indicators with a corresponding weight for the evaluation indicator, which is included in the first data.

An allocation design apparatus, comprising:

• a memory;
• and
• a processor configured to use the memory and execute a process comprising:
• receiving a request to allocate one or plural virtual machines for a system that includes the one or plural virtual machines to one or plural physical machines;
• selecting first data concerning one or plural evaluation indicators for a requesting source user of the request among data that is concerned with one or plural evaluation indicators for virtual machine allocation and is registered in advance for each of a plurality of users;
• first calculating, for each virtual machine of the one or plural virtual machines, a first cost in case where the virtual machine is allocated to any one of usable physical machines of the one or plural physical machines, based on the selected first data to identify, for each virtual machine of the one or plural virtual machines, a physical machine for which the calculated first cost is the least among the one or plural physical machines;
• generating allocation design data including second data concerning the physical machine identified for each virtual machine of the one or plural virtual machines;
• and
• allocating the one or plural virtual machines according to the generated allocation design data, wherein
• the first calculating comprises
• for each virtual machine of the one or plural virtual machines,
• calculating a second cost for each of the usable physical machines of the one or plural physical machines for each of evaluation indicators included in the first data;
• and
• calculating, for each of the usable physical machines of the one or plural physical machines, the first cost by adding the second cost calculated for each evaluation indicator of the evaluation indicators with a corresponding weight for the evaluation indicator, which is included in the first data.
