Nowadays cloud computing industry has turned to the stage of small-scale application from the stage of import and preparation, so business model has become an integral part in cloud computing. According to the existing problem of commercial operation in cloud computing, by analyzing and forecasting the service composition effects, this paper proposes the theoretical thought of synthetic prediction of risk management for cloud computing services composition systems, gives a synthetic prediction model of services composition, namely multi-layer recurrent model, and analyzes it properties. Then based on multi-layer recurrent model, the construction and application prospect of the cloud service platform based on cloud computing service portfolio is discussed.
