In recent years, considerable attention has been given to organizing the computing resources in a data centre as a common infrastructure to be shared by multiple applications. Each application has its own workload and performance goal. The workload is time-varying because the demand from users may change over time. In managing the resources in a data centre, an important consideration is to achieve efficient resource utilization and high probability of meeting the performance goal of individual applications. Virtualization technology can be used to improve flexibility in resource management. Applications are deployed on virtual machines which are implemented on physical resources. By dynamically allocating these resources to virtual machines, the system can adapt to changing workloads and provide good performance to individual applications.

近年来，将数据中心内的计算资源组织为由多个应用程序共享的公共基础设施受到了相当大的关注。每个应用程序都有自己的工作负载和性能目标。工作负载是时变的，因为用户的需求可能随时间变化。在管理数据中心的资源时，一个重要的考虑因素是实现有效的资源利用和高概率地满足单个应用程序的性能目标。虚拟化技术可以提高资源管理的灵活性。应用程序部署在虚拟机上，虚拟机在物理资源上实现。通过动态地将这些资源分配给虚拟机，系统可以适应不断变化的工作负载，并为各个应用程序提供良好的性能。
