Cloud computing allows business customers to scale up and down their resource usage based on needs. The authors present a system that uses virtualization technology to allocate data center resources dynamically based on application demands and support green computing by optimizing the number of servers in use. They introduce the concept of "Skewness" to measure the unevenness in the multidimensional resource utilization of a server. By minimizing imbalance, they will mix completely different of workloads nicely and improve the overall utilization of server resources.
