A Survey of Virtualization Performance in Cloud Computing
نویسنده
چکیده
Virtualization is an important resource of cloud computing. Many virtualization technologies allow workload consolidation, multiple operating systems, and fault tolerance mechanisms. The number of applications moving to the cloud is increasing, and cloud computing is becoming a prominent distributed computing framework. Virtual machines provide many benefits to these applications. Thus, it is critically important to examine and review the performance effects of virtualization in cloud computing environments. This survey outlines research and experiments that have been done to test the effects virtual machines in cloud computing environments. Applications such as Web 2.0 and high performance computing are considered. Benchmarking and experimental tools are introduced. Results from studies have show that CPU sharing in Amazon EC2 small instances degrades network performance. Live server migration may affect Web 2.0 technologies if operating at peak workloads. HPC benchmarking tools show Xen may have significant variance in performance compared to KVM and VirtualBox.
