Many companies offer their own cloud services, in fact, we have unwittingly using these cloud services, such as Google Maps and Apple multimedia services. In general, by applying the virtualization technologies, the data center is built for cloud computing to provide the computing and storage resources, as well as the software environment for users.
In order to reduce energy consumption of the data center, by applying the dynamic voltage scaling and load balancing technologies, a new scheduling strategy has been proposed in this thesis to improve the system performance in the cloud computing environment. For saving energy consumption, the system voltage will be adjusted dynamically according to the utilization of each host CPU. Furthermore, the virtual machine will be migrated appropriately to achieve the purpose of energy saving and load-balancing. The experimental results show that about 4% to 14%energy can be saved by applying the proposed mechanism, and a better load-balancing can also be achieved. Some key techniques will also be discussed in the thesis.
