A scripting based architecture for management of streams and services in real-time grid applications

Recent specifications such as WS-management and WS-distributed management have stressed the importance of management of resources and services and propose methods towards querying Web services to gather the meta-data associated with these services. Management often entails system setup, querying system metadata, manipulation of system parameters at runtime and taking actions based on the system parameters to tune system performance. Real-time applications require rapid deployment of application components and demand results in real time. In this paper we present the HPSearch system which enables dynamic management of the system including both streams and Web services, and rapid deployment of applications via a scripting interface. We illustrate the functioning of the system by modeling a data streaming application and rapidly deploying the system and application components.
