A Cloud Computing Management System Platform Based On Power-sensitive Resource

this paper addresses the issue of hosting multiple clusters of Virtual Machines (i.e., multiple Virtual Clusters) in a single physical cluster system. Multiple Virtual Clusters (VCs) cohabit in the physical cluster, with different VCs serving different types of requests. There are two levels of VC managers in the framework: local manager and global manager. Every VC has its local manager. The framework developed in this paper aims to consume the minimal number of physical nodes (therefore minimized power consumption) to deliver desired QoS(Quality of Service) for all VCs.
