摘要
本文对云计算虚拟化技术的概念及其发展现状进行了阐述,并对虚拟化技术在云计算中的应用进行了具体分析。虚拟化技术包括虚拟整合、虚拟拆分和虚拟迁移。云计算使用虚拟整合技术将云平台中异构的物理资源整合成一个资源池,方便对资源的管理和分配;虚拟拆分将每台服务器拆分为多个虚拟机,通过虚拟桌面技术,每个用户能独占一个虚拟机,运行自己的应用,互不影响;虚拟迁移技术能够帮助云平台进行负载均衡和节约运行成本。最后对几种虚拟软件的性能进行了测试对比,分析了虚拟化带来的资源损耗问题。
This article describes the concept and development of cloud computing and virtualization tech- nology, and specifically analyses the application of virtualization technology in the cloud. Virtualization technolo- gy consists of virtual integration, virtual split and virtual migration. The heterogeneous physical resources in the cloud platform is integrated into a resource pool to facilitate the management and allocation of resources by using the virtual integration in the Cloud computing. Each server is split into multiple virtual machines by using virtual split technology, virtual desktop technology allows each user can monopolize a virtual machine, run their own ap- plications, independently of each other. Virtual migration technology can help cloud platform for load balancing and operating cost saving. Finally, the performance of several virtual software was tested and compared.
