The word "autonomic" means acting or occurring involuntarily. Autonomics is used to describe an action or response that occurs without conscious control. In physiology, it relates to the activities controlled by the autonomic nervous system (ANS).
Autonomic computing is the ability to manage your computing enterprise through hardware and software that automatically and dynamically responds to the requirements of your business. This means self-healing, self-configuring, self-optimizing, and self-protecting hardware and software that behaves in accordance to defined service levels and policies. Just like the autonomic nervous system responds to the needs of the body, the autonomic computing system responds to the needs of the business.
