Building Distributed Access Control System Using Service-Oriented Programming Model

Service-oriented programming model is a new methodology for building service-oriented applications. In the service-oriented programming model, an application is assembled from loosely coupled, dynamically bounded services that mutually cooperate and compete in order to achieve the application ´s goal. In this paper, we present our experiences with the service-oriented programming model attained through development and testing of access control system. The access control system is a service-oriented application that manages security in the virtual organizations. We indicate how service-oriented programming model facilitates run-time reconfiguration of the access control system. Further, we evaluate and compare the performance of several architectures of the access control system with different levels of parallelism and concurrency
