云计算层次服务关联机制及SaaS模式下数据安全取向的研究

摘要

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.%本文首先介绍了云计算特征与分类、云服务模式，其次，由云计算的开放类型：公有云、私有云、混合云等展开叙述，分析了云计算体系结构与云服务模式融合、云计算层次结构与服务类型关联机制、SaaS体系结构与安全隐患，最后阐述了SaaS模式下数据的安全取向，具体分析了系统管理与物理安全、数据传输与网络安全、数据存储与冗余备份、强化软件效用提升云服务安全等。
