Cloud Service Recommendation: State of the Art and Research Challenges Cloud computing is an attractive platform which offers on-demand resources as services. When manycloud services are available, some may have similar or same functionalities. So cloud service recommendation, which can help users to select the services based on their preferences, become an important technique for cloud services. In this paper, we review the relevant technologies that can perform cloud service recommendation. First, we introduce the web service selection and recommendation technologies. Next, we describe QoS measurement for cloud service and different recommendation methods focusing on Collaborative filtering. Third, we discuss the research challenges and opportunities for cloud service recommendation. This paper is expected to benefit both academic and industry.
