基于SOA的分布式应用系统的缓存设计研究

面向服务的体系结构（SOA）作为解决分布式系统开发中软件重用，互操作，提高软件开发效率的有效途径，其性能受到研究和应用双方面的关注。设计良好的缓存机制，减少分布式环境中相当耗费资源的远程服务的响应时间，是实际应用中的关键。引入了ASP.NET 2.0中的缓存机制，以一个基于SOA的大型分布式系统中的应用为例，设计了包括浏览器，IIS页面和应用数据缓存的方案，并为应用数据缓存设计了刷新机制。给出了部分代码实现。

The Research on cache design in distributing application system based on SOA

Service Oriented Architecture (SOA) is proposed recent years to improve the reusability, interoperability, and efficiency in distribute software development. Its performance raises a lot of interest in both researchers and practitioners. Designing a standout caching mechanism, reducing the response time of costly remote service invocations in such environments is a critical challenge in many real life cases. The caching mechanism in ASP.NET2.0 is introduced, and a cache design approach in a large SOA based distribute applications ystemi s describedd etailed. Thei ntegrated approach contains the browser, IIS Page and the application data cache with a refresh mechanism designed. The part realization of this solution is given, too.
