自从IBM加入到Globus联盟(www.globus.org,网格的标准制定者和标准实现开发者)之后，OGSA的推出，GlobusToolkit3.0版的推出，网格的功能就被整合到基于WebServices的Grid Service外壳之中，Web Services和网格计算两大阵营出现了结合的趋向。
Grid Service与Web Service的区别在于Grid Service支持接口继承和服务状态，状态变化的异步通知机制，等等。
但是随着WSDL1.2、Web服务资源框架规范（WS Resource Framework，简称WSRF）和Web服务通知规范（WS Notification specifications，简称WSN）的即将推出，来自不同背景的两大团体似乎越走越近，
我不禁有些担心，在整个过程中，网格计算是否可能失去自我。
不过Ian Foster还是认为网格计算解决了Web服务没有触及或者没有解决好的问题“The essential requirement addressed by OGSI and WSRF the critical functionality missing from Web services from a Grid perspective is the ability to create, address, inspect, discover, and manage stateful resources.”－－有状态的资源。
