阐述了虚拟化技术是云平台实现的关键技术,虚拟化性能是衡量云平台性能的重要标准。为评测与研究云平台的虚拟化性能,建立了一种云平台虚拟化性能评测模型,并对UCloud和百度开放云平台这两个云平台的虚拟机性能及其损失、虚拟资源分配和虚拟机稳定性进行了测试,并对测试结果进行了分析。结果表明,建立的评测模型可以准确地分析UCloud云平台和百度开放云平台的虚拟化性能,可以应用于其它云平台虚拟化性能的评测。
The study described that the virtualization technique is the key to implementation of a cloud platform and the virtualization performance is an important criterion for measurement of a cloud platform' s performance. To evaluate and study the virtualization performance of cloud platforms, a virtualization performance evaluation model was estab- lished, and it was used to test the virtual machine's performance and loss, the virtual resource allocation and the virtual machine' s stability of the cloud platforms of UCloud and Baidu Open. The analysis of the testing results show that the evaluation model can accurately measure the virtualization performance of the cloud platforms UCloud and Baidu Open. The evaluation model can be applicable to evaluation of other cloud platforms, virtualization per- formance.
