Abstract

Method, computer program products and systems for conserving energy in data processing center, wherein a plurality of services are offered to a plurality of subscribed service consumers in a dynamic fashion, allowing a created service instance to be re-assigned from one to another server of the resources. Control parameters comprising power consumption and temperature of a group of resources are monitored. A workload may be assigned properties such as “hot” and “cold.” which are then assessed. A hot workload may be relocated to a cold spot, and if necessary, a cold workload may be relocated to a location which was de-loaded from a workload, that is, a hot spot, which is then considered to cool down due to addition of less workload in form of the cold workload. Thus, the energy required to cool the data center may be minimized.
