Abstract

The integrated resource management unit 202 manages some of the resources 311 a, 311 b, 311 c and prepares a plurality of containers 310 provided as virtual resources, with respect to the application programs. In response to a predetermined request that is issued with respect to a tenant 300 a or 300 b that is configured to divide a resource to be used, the integrated resource management unit provides a request-source tenant with a container selected from among the plurality of containers. In the container that is provided to the request-source tenant by the integrated resource management unit, a resource, which is allocated beforehand to an application program designated by the predetermined request, is occasionally configured to have usage lower than a designated usage.

First claim

The invention claimed is:

1. A resource management system managing resources, comprising:
a plurality of physical computers configured to provide the resources;
a plurality of virtual computers configured to execute at least one of application programs; and
an integrated resource management unit that is coupled communicably to the plurality of physical computers and the plurality of virtual computers, wherein the integrated resource management unit is configured to:
prepare a plurality of containers for managing some of the resources associated therewith and providing these resources as virtual resources; and
manage a resource division that defines a use range of the provided virtual resources,
the plurality of containers are configured to be associated with any of the application programs, and, upon receipt of a resource configuration change request regarding an application program operated in the resource division, migrate the resources managed by the other containers to the containers associated with the application program, and
the amount of resources managed by the other containers is occasionally lower than the amount of virtual resources provided by the other containers,
wherein the integrated resource management unit associates a first predetermined resource, which is part of the resources associated with a first container provided to a first resource division of a plurality of resource divisions, with a second container that is provided to a second resource division of the plurality of resource divisions, and thereby migrates from the first resource division to which the first predetermined resource belongs, to the second resource division,
wherein the integrated resource management unit manages utilization rates of a plurality of resources used by the application programs, and selects a resource exhibiting a lowest utilization rate as the first predetermined resource from among the plurality of resources, and
wherein the integrated resource management unit manages performance degradation of each of the plurality of resources, and, when the performance degradation of the resource with the lowest utilization rate is lower than a predetermined value, selects, as the first predetermined resource, a resource that has the lowest utilization rate and performance degradation lower than the predetermined value.

2. The resource management system according to claim 1 , wherein the integrated resource management unit determines whether the first predetermined resource satisfies a predetermined restriction condition used by a second application program, and selects, as the first predetermined resource, a resource that has the lowest utilization rate and performance degradation lower than the predetermined value and satisfies the predetermined restriction condition.

3. The resource management system according to claim 2 , wherein
the integrated resource management unit
is coupled communicably to a first application management unit for managing a first application program that uses the first container, and to a second application management unit for managing a second application program that uses the second container,
invalidates old access authority information that is configured in the first predetermined resource and used by the first application management unit to access the first predetermined resource, when migrating the first predetermined resource from the first container to the second container,
deletes the old access authority information from the first application management unit,
generates new access authority information and configures the new access authority information in the first predetermined resource,
configures the new access authority information in the second application management unit,
confirms that access authority for enabling access to the first predetermined resource is migrated from the first application management unit to the second application management unit, and
deletes the old access authority information from the first application management unit.

4. The resource management system according to claim 1 , wherein the integrated resource management unit executes predetermined computation using an actual value of a predetermined performance index that is configured in advance for each of the resources associated with the plurality of containers, thereby calculates a performance evaluation value for evaluating performance of each of the plurality of containers without relying on types of the application programs that use the containers, and presents the calculated performance evaluation values.

5. The resource management system according to claim 1 , wherein
the integrated resource management unit executes predetermined computation using an actual value of a predetermined performance index that is configured in advance for each of the resources associated with the plurality of containers, thereby calculates a performance evaluation value for evaluating performance of each of the plurality of containers without relying on types of the application programs that use the containers, and notifies an apparatus issuing the predetermined request of the calculated performance evaluation values,
the predetermined request being a request for addition of the resources which are determined to be bottlenecks, based on the performance evaluation values.

6. The resource management system according to claim 1 , wherein
the integrated resource management unit
executes predetermined computation using an actual value of a predetermined performance index that is configured in advance for each of the resources associated with the plurality of containers, thereby calculates a performance evaluation value for evaluating performance of each of the plurality of containers without relying on types of the application programs that use the containers,
manages performance degradation of each of the plurality of containers based on the calculated performance evaluation values, and
when the performance degradation of the container having the lowest utilization rate is lower than a predetermined value, selects, as the first predetermined resource, a resource that has the lowest utilization rate and performance degradation lower than the predetermined value.

7. A resource management method for managing resources of an information processing system by using a management computer, wherein
the information processing system is configured to have a plurality of physical computers that provide the resources, a plurality of virtual computers that execute at least one of application programs, and the management computer that is coupled communicably to the plurality of physical computers and the plurality of virtual computers,
the management computer is configured
to prepare a plurality of containers for managing some of the resources associated therewith and providing these resources as virtual resources, and
to manage a resource division that defines a use range of the provided virtual resources,

the plurality of containers are configured to be associated with any of the application programs, and
upon receipt of a resource configuration change request regarding an application program operated in the resource division, migrate the resources managed by the other containers to the containers associated with the application program, and
the amount of resources managed by the other containers is occasionally lower than the amount of virtual resources provided by the other containers,
wherein the management computer associates a first predetermined resource, which is part of the resources associated with a first container provided to a first resource division of a plurality of resource divisions, with a second container that is provided to a second resource divisio
