Towards requirements-driven autonomic systems design

Autonomic computing systems reduce software maintenance costs and management complexity by taking on the responsibility for their configuration, optimization, healing, and protection. These tasks are accomplished by switching at runtime to a different system behaviour – the one that is more efficient, more secure, more stable, etc. – while still fulfilling the main purpose of the system. Thus, identifying the objectives of the system, analyzing alternative ways of how these objectives can be met, and designing a system that supports all or some of these alternative behaviours is a promising way to develop autonomic systems. This paper proposes the use of requirements goal models as a foundation for such software development process and sketches a possible architecture for autonomic systems that can be built using the this approach
