Cfengine is an automated suite of programs for configuring and maintaining Unix-like computers. It has been used on computing arrays of between 1 and 20,000 computers since 1993 by a wide range of organizations. Cfengine is supported by active research and was the first autonomic, hands-free management system for Unix-like operating systems.
Cfengine is an autonomic maintenance system not merely a change management roll-out tool. Cfengine has a history of security and adaptability.
