A Dynamic Resource Management with Energy Saving Mechanism for Supporting Cloud Computing

Cloud computing is becoming an important opportunities for industry to provide a high degree of scalability and serviceability of computing resources. In order to integrate the system resource, utilize the resource flexibly, save the energy consumption, and meet the requirements of users in the cloud computing environment, one of the positive solutions is to apply the virtualization technology. A dynamic resource management with energy saving mechanism has been proposed in this paper which presents a method of dynamic voltage scaling for dynamic adjustment of resources by inspecting CPU utilization in the cloud computing environment. The voltage of the idle or light loaded computer can be reduced and heavy loaded works can be migrated to those machines with lighter loading for achieving the purpose of energy saving. The experimental results show that at the user unaware situation, energy consumption can be saved significantly by applying the proposed mechanism.
