The increasing scale complexity, heterogeneity and dynamism of net-works, systems and applications have made our computational and informationinfrastructure brittle, unmanageable and insecure. This has necessitated the in-vestigation of an alternate paradigm for system and application design, which isbased on strategies used by biological systems to deal with similar challenges –a vision that has been referred to as autonomic computing. The overarching goalof autonomic computing is to realize computer and software systems and ap-plications that can manage themselves in accordance with high-level guidancefrom humans. Meeting the grand challenges of autonomic computing requiresscientific and technological advances in a wide variety of fields, as well as newsoftware and system architectures that support the effective integration of theconstituent technologies. This paper presents an introduction to autonomic com-puting, its challenges, and opportunities.
