摘要
云计算是集分布式计算、效用计算、网格计算、虚拟化等技术与一体的,通过互连网部署和提供服务的新的计算模式,计算资源以可升级的、按需定制的服务的形式通过Internet提供云计算仍处于初级阶段,许多关键技术需要进一步研究解决本文综述了云计算的起源与发展现状,描述云计算体系结构模型、剖析工业界有代表性的云服务产品的体系结构与技术特点。
Cloud computing is a new emerging computing paradigm for hosting and delivering services over the Internet,where computing resources are offered over the Internet as scalable,on-demand（Web） services.It is a convergence of distributed computing,utility computing,grid computing and virtualization.However,the development of cloud computing technology is currently at its infancy,with many key issues still to be addressed.In this paper,we present state of the art of cloud computing,describing the reference model of cloud computing architecture,analyzing the architectures and characteristics of commercial representative cloud products and open source project,highlighting the key technologies of cloud computing.The aim of this paper is to identify important research directions in this increasingly important area.
