Abstract: The three-layer service architecture（SaaS, PaaS and IaaS） of computing has a deep impact on the enterprise information system construction. Among them, the selection of Platform as a Service（PaaS） products, which is not solved by a perfect solution, has become a thorny issue in the construction of the enterprise private cloud. Therefore, a framework of enterprise PaaS platform product selection is proposed. This paper respectively studies the enterprise service oriented architecture integrated with cloud computing pattern, the construction method of PaaS products measuring metrics and multi-attribute products selection decision-making process based on ANP from three aspects of PaaS product selection, namely requirement analysis, measuring indexes and selection method. This paper shows the effect of the framework on improving the decision-making ability of enterprise PaaS platform products selection by a case.

Key words: platform as a service, production selection, requirement modeling, measuring index, selection framework

摘要： 云计算的三层服务架构（SaaS、PaaS、IaaS）正深刻地影响着企业信息化系统建设，其中平台即服务（PaaS）产品选择问题成为当前企业私有云构建中的棘手问题，至今仍无好的解决方法。为此，提出一个企业PaaS平台产品选择框架，分别从PaaS产品选择的需求分析、测评指标和评选方法三方面研究融合云计算模式的企业面向服务体系架构，PaaS产品评价指标体系的构建方法和基于ANP的多属性产品选择决策过程。通过一个案例展示该选择框架在提高企业PaaS平台产品选择决策水平中的作用。
