Performance evaluation of distributed systems

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.
