Management of hardware resources included in a communication system

A resource management system, comprising one or more processors, the resource management system causing at least one of the one or more processors to execute:

• a usage status monitoring process of monitoring a usage status of each of a plurality of hardware resource groups included in a communication system;
• a resource addition process of changing, in response to the usage status of any one of the plurality of hardware resource groups satisfying a resource addition condition associated with the hardware resource group, an affiliation of a hardware resource included in a common spare resource group different from all of the plurality of hardware resource groups from the common spare resource group to the hardware resource group;
• and
• a setup execution process of executing setup corresponding to a predetermined type of application,
• wherein, when a surplus level of a hardware resource included in a special spare resource group which is a part of the common spare resource group and which includes hardware resources on which the setup corresponding to the predetermined type has been executed satisfies a predetermined surplus condition, in response to the usage status of any one of the plurality of hardware resource groups in which the predetermined type of the application is operating satisfying the resource addition condition associated with the hardware resource group, in the resource addition process, the affiliation of the hardware resource included in the special spare resource group is changed from the special spare resource group to the hardware resource group, and
• wherein, when the surplus level of the hardware resource included in the special spare resource group does not satisfy the predetermined surplus condition, in response to the usage status of any one of the plurality of hardware resource groups in which the predetermined type of the application is operating satisfying the resource addition condition associated with the hardware resource group, in the setup execution process, the setup corresponding to the predetermined type of the application is executed on a hardware resource included in a general-purpose spare resource group which is a part of the common spare resource group and which includes hardware resources on which the setup has not been executed, and in the resource addition process, the affiliation of the hardware resource on which the setup has been executed is changed from the general-purpose spare resource group to the hardware resource group.
