A model-driven framework for enterprise service management

With a steady pace of adoption of service-oriented architecture, enterprises have made significant progresses in implementing various kinds of Web services and converting existing applications to service-oriented architecture. As a significant number of services have been put into actual use, many service-oriented enterprises are faced with the problem of how to manage these services efficiently. In this paper, we propose a model-driven framework for a more efficient management of these services. In this framework, the creation and maintenance of enterprise integration solutions are modeled by flows, finite state machines (FSMs), role-based access control (RBAC) among other formal systems models as well as appropriate decision models. For instance, each enterprise integration solution would be modeled as composite services that can be described by respective flow, FSM and RBAC models. These solution models can then be stored, and later retrieved for the execution of these composite services. Furthermore, formal systems and decision models are also used to maintain and update these service-oriented solutions to improve the efficiency and quality of service management by taking advantage of the underlying service-oriented architecture.
