PROBLEM TO BE SOLVED: To balance loads between two physical resources.SOLUTION: For each physical resource, a system establishes resource-usage models for a plurality of jobs that share the physical resource, identifies quality-of-service (QoS) levels associated with the jobs, and computes a QoS balance point for the physical resource on the basis of the resource-usage models and the QoS ratings. The QoS balance point indicates a rating of QoS, substantial resource provisioning being required when exceeding the Qos balance point. In response to detecting a difference between a first QoS balance point 218 associated with a first physical resource 202 and a second QoS balance point 220 associated with a second physical resource 204, the system identifies one or more jobs 222 to be moved between the first and second physical resources such that the difference between the first and the second QoS balance points is reduced. |
