Firstly, this paper introduces the classification and features of cloud computing, cloud service model, secondly, from cloud open type: public cloud and private clouds, mixed clouds narrative, analyzes cloud computing fusion, system structure and cloud service model of cloud computing mechanism, hierarchical structure and service type associated with SaaS architecture and security risks. Finally data safety oriented SaaS mode is elaborated, such as system management and physical security, network security, data transmission and data storage and redundancy backup, strengthen software utility to improve cloud service security and so on are discussed.
