Computer-readable recording medium storing resource management program, resource management method, and management device

A resource management method for causing a computer that manages a virtualization system to execute a process, the process comprising:

• obtaining a first score according to a time-series number of unused resources for each resource type in the virtualization system, based on a use history of resources in the virtualization system by a user;
• obtaining, for each resource, a second score according to a use frequency and compatibility with another resource;
• and
• allocating each resource to the user in ascending order of a total value of the first score and the second score,
• wherein the process allocates each resource to the user in a case where a resource use rate of the virtualization system is higher than a predetermined value, and
• when the resource use rate of a current and a future virtualization system is higher than a upper limit threshold and shortage is solved by changing the resource to a resource in a past deployment history of a requesting user, changes a selected resource to the resource in the past deployment history of the requesting user.

A management device that manages a virtualization system, the management device comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• obtain a first score according to a time-series number of unused resources for each resource type in the virtualization system, based on a use history of resources in the virtualization system by a user;
• obtain, for each resource, a second score according to a use frequency and compatibility with another resource;
• and
• allocate each resource to the user in ascending order of a total value of the first score and the second score,
• wherein the processor allocates each resource to the user in a case where a resource use rate of the virtualization system is higher than a predetermined value, and
• when the resource use rate of a current and a future virtualization system is higher than a upper limit threshold and shortage is solved by changing the resource to a resource in a past deployment history of a requesting user, changes a selected resource to the resource in the past deployment history of the requesting user.
