Developing Ubiquitous Collaborating Services in Grid Environment

Abstract

Grid computing provides a world largest ubiquitous collaborative environment that allows a number of applications to communicate with each other in order to share computational resources and services seamlessly within this environment. In this paper, we propose a viable execution environment to enable these ubiquitous services, also known as grid services to collaborate through WS-BPEL (Web Services Business Process Execution Language) engine. Grid services are stateful software components running on grids and WS-BPEL is business workflow description language that is useful for coordinating grid services as it is for stateless web services. But WS-BPEL engine is mainly used for running business process workflows by facilitating collaboration of stateless web services, with little or no direct support for grid services collaboration. So, the main focus of this paper is to propose an execution environment that will enable grid services collaboration using WS-BPEL engine, by providing a direct approach that attempts to minimise developer efforts. Finally, a comprehensive grid demonstration application is adopted to illustrate the application of the proposed approach within the execution environment.
