云计算的基础结构设计和云应用服务

Design of Infrastructure of Cloud Computing and Cloud Applications Services

云计算是基于云结构的信息技术资源消费与利用系统,也是基于互联网的链路传输系统与终端服务系统的集成应用模型。典型的云服务模型包括Saa S/Aaa S、Iaa S、Paa S、Daa S,这些参考模型同时组成云系统应用服务基础架构。云计算开发标准与规则是云结构发展与云数据库的开发参考基准,也是云管理与云进化的参考结构。云系统服务质量关系云应用发展,而云管理的服务配置与监视服务提供反馈信息。云应用服务维护运行与数据安全是云安全提供的基础保障服务。云备份作为领导性企业云的高级服务功能应能适应云灵活多变性与容灾免灾设计,文中深入分析云数据备份技术应用与程序算法,细述实用数据应用处理方法。动态开发环境是企业云对云计算开放研究平台,在全球推进云环境的开发测试。云计算风险分析与管理同时促进云应用进化。

Cloud computing is the deployment system of cloud-based IT resources’consumption,also the integrated applications’ model of internet-based link transmission and terminals services system.The typical model of cloud services should include SaaS/AaaS、IaaS、PaaS、DaaS,these references may constitueinfrastructure of cloud system services.Cloud computing development standards and requirements have been thought of as the development references and basics of cloud structure development and cloud databases,as well as regarded references structure of cloud management and evolution.QoS of cloud system may depend upon cloud applications developments,furthermore,services’ configuring and monitoring of cloud management may provide feedback.Cloud applications services’ maintenance and data security must be provided primary guarantee services by cloud security.Cloud backup only leading enterprise cloud can keep the advanced services func-tions so as to adapt to cloud flexibilities and disaster-avoiding and disaster-free design,the paper analyzes deeply the technical applications and program algorithms of cloud datum plus illustrates detailedlypratical datum processing methods.Dynamic development environment has become the open research platform of cloud computing among enterprise clouds,and taken the testing according to cloud environment development across the globe .Meantime,cloud computing risk analysis and manage-ment can prompt evolving cloud applications.
