Configuration management encompasses the processes and tools used to maintain consistency and control over the configuration of software, systems, and infrastructure throughout their lifecycle. It involves:
-
Identification: Identifying all configuration items (CIs) within the system, including software, hardware, documentation, and network components.
-
Control: Implementing procedures and policies to control changes to configuration items, ensuring that only authorized changes are made and properly documented.
-
Version control: Managing and tracking different versions of configuration items, including changes, updates, and releases.
-
Configuration baselines: Establishing baselines to define the standard configuration of the system at specific points in time, serving as a reference for future changes.
-
Change management: Implementing processes for requesting, evaluating, approving, and implementing changes to configuration items, while minimizing risks and disruptions.
