A cloud computing service is the next-generation core service of green ICT for operational management of ICT resources and maximization of energy consumption efficiency. Cloud service is expected to rapidly increase in its market size in the future through its convenience in usage, efficiency of operational management and economic effects and so on. In users' perspectives, the choice of the appropriative cloud service is very important to meet their business goals and strategies. A cloud service selection problem is a multiple-criteria decision analysis with feedback. An Analytical Network Process (ANP) is a popular decision analysis technique. This study proposes a cloud service selection model based on ANP. According to the proposed model, the criteria and sub-factors for cloud service selection are identified and then determined their weights. In this study, ANP based the multiple criteria decision-making model is applied to choose the best cloud services.
