摘要:

云计算是以虚拟化技术为基础,以网络为载体提供基础架构、平台、软件等服务为形式,整合大规模可扩展的计算、存储、数据、应用等分布式计算资源进行协同工作的超级计算模式。作为一种全新的互联网应用模式,云计算将成为未来人们获取服务和信息的主导方式。针对当前云计算概念混杂的现状,提出了一个较综合的参考性定义,并分析了云计算与分布式计算、网格计算、并行计算、效用计算等相关计算形式的联系与区别。对目前主流的云计算平台实例进行了概括性介绍,从云平台的层次更深刻地剖析云计算的本质。

Abstract:

As a model of supercomputing based on virtualization,cloud computing provided the IaaS、PaaS、SaaS services via Internet,which will integrate all the large-scale and extensible distributed computing resources such as computing、storage、data and application for cooperative work.It’s an entirely new Internet application mode and will be the leading way to access services and information in the near future. With consideration of the status of mixed concepts,a reference definition was put forward after the introduction of the cloud computing basic concept,and then its difference with distributed computing,grid computing,parallel computing and utility computing were analyzed. In the end,the case of mainstream cloud computing platforms were introduced in helping to profound understand what’s the cloud computing form platform view.

Key words: cloud computing, concept, platform
