CWS服务平台的设计与实现——一个基于Web服务技术的计算资源共享系统

Design and Implementation of CWS Service Platform——A Computing Resource Sharing System Based on Web Services Technology

Web服务和网格计算技术,出现了日益融合的趋势,网格计算已经进入了服务为中心的新阶段。在这种情况下,就可以在具有良好跨平台性和互操作性的Web服务框架上实现计算资源的共享。论文提出了CWS服务和支撑CWS服务注册发布和共享运行的平台系统。在平台系统实现的过程中解决了几个关键问题。目前,已在北京大学计算机系的校园网内搭建了CWS服务平台,成功运行了多个服务实例。

Web Services and Grid computing technologies are getting closer with each other,which marks the entry for Grid computing into service-oriented phase.Under such a circumstance,computing resource sharing can be achieved on the foundation of portable and interoperable Web Services infrastructure.The paper proposes the concept of CWS services and a hosting platform to register,publish and execute CWS services.During the course of implementation, several key problems are resolved.At present,a CWS service platform has been established in the campus networks of department of computer science,Peking University,on which several services cases are successfully running.
