A Model-Driven Architecture Approach for Modeling, Specifying and Deploying Policies in Autonomous and Autonomic Systems

Abstract

Autonomic Computing (AC), self-management based on high level guidance from humans, is increasingly gain ing momentum as the way forward in designing reliable systems that hide complexity and conquer IT management costs. Effectively, AC may be viewed as Policy-Based Self Management. The Model Driven Architecture (MDA) ap proach focuses on building models that can be transformed into code in an automatic manner. In this paper, we look at ways to implement Policy-Based Self-Management by means of models that can be converted to code using trans formations that follow the MDA philosophy. We propose a set of UML-based models to specify autonomic and au tonomous features along with the necessary procedures, based on modification and composition of models, to deploy a policy as an executing system.
