开源IaaS云服务软件平台的分析与比较

作为一种新兴的计算模式,云计算已经由最初的理论探索,逐渐进入了理论、技术与实际应用共同发展的阶段。开源云平台项目的研究与发展在其中起到了重要作用。迄今为止,使用开源IaaS云平台搭建自己的公共云或私有云,已经成为很多学术机构和商业企业信息管理、信息服务和技术研究中经济而有效的解决方案。为了评价和选择合适的IaaS云平台,根据NIST云模型,从体系结构、资源抽象和控制技术、云服务管理、安全策略、社区规模及活跃度和基本情况等多个方面 抽象出详细指标,对4个具有代表性的开源IaaS云平台软件进行了研究、分析和比较。

Analysis and Comparsion of Open Source IaaS Platform

As a new computing model,cloud computing has been explored from the initial theoretical stage gradually into a common development of theories,techniques and applications,while the research and development in open cloud projects play an important role.So far,many academic institutions and commercial enterprise have considered open cloud as an economical and effective solution of building public cloud or private cloud for information management,information services and technology research.In this paper,we presented a comparative study about four open IaaS platforms.We discussed in detail about their architecture,resource abstraction and control layer,cloud service management,security,the scale of community and so on.We hoped that this paper can provide a clear guide for evaluating the possible adoption of cloud technology.
