摘要
从ASP(Application Service Provider)商业模式常用集中化模型出发,指出其存在的问题,并以此提出了一个分层服务管理(DSM)模型,此模型用分布运算来解决由于原模型的高度集中化环境带来的高性能、高安全性和高可靠性要求等问题.DSM模型主要由功能组件集、控制中心、事件服务和日志服务四个部件组成,通过各部件间的相互协作实现信息收集处理、资料备份管理、服务部署管理、事件管理和日志管理五个域的管理需求.最后介绍了一个以JMX为核心技术来实现的DSM原型系统及其开发方向.
Recently, the application service proider （ASP） model is widely used in delivering high-end business application because of the significantly reduced IT cost. However, the centralized pure ASP model inherits the drawbacks from central data centre, such as single-point failure, hard to customized, etc. A new delamination service management （DSM） model which uses distributed computing to overcome the issues of the pure ASP model, is put forward. The new model aims to provide a system with high performance, security and reliability. The model composes of four main components, functionality modules, control centre, event service and log service. There are five kinds of management, data collection management, system backup management, service distributing management, event management and log management. Finally, a JMX implementation of DSM model is introduced to evaluate the model; and the possible future work of DSM, is given.
