摘　　要：云计算是一种商业计算模型，它将计算任务分布在大量计算机构成的资源池上，使各种应用系统能够根据需要获取计算力、存储空间和信息服务。云计算的基本原理是利用非本地或远程服务器（集群）的分布式计算机为互联网用户提供资源服务。云计算有SaaS、PaaS和IaaS三类应用模式。云计算有公共云、私有云和混合云三类部署方式。云计算是网格计算、分布式计算、并行计算、效用计算、网络存储、虚拟化、负载均衡等传统计算机技术和网络技术发展融合的产物，是一种基于因特网的超级计算模式。云计算有四个基本特征。The cloud computing is a commercial calculation model,the distribution of computing tasks in a pool of computer resources,make all kinds of application system can according to the need for computing power and storage space and information services.Cloud calculative fundamental principle is to use the local or remote server（cluster of distributed computer）offer for Internet user resource service.Cloud computing has SaaS,PaaS and IaaS three kinds of application mode.Cloud computing has the public cloud,private clouds and mixed cloud deployment way three.Cloud computing is grid computing,distributed computing,parallel computing,utility computing,network storage,virtualization,load balance of traditional computer technology and network technology development of fusion product,is a kind of Intemet super based on calculation mode.Cloud computing has four basic characteristics.
