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.
