About Configuration Items

A configuration item (CI) is a component of your organization’s infrastructure that is under the control of Configuration Management. A configuration item can represent hardware, software, or associated documentation. For example, configuration items can include services, servers, equipment, network components, desktop and mobile computers, applications, licenses, telecommunication services, and facilities.
When you work a change request, you can associate it with one or more configuration items. ITIL recommends that each change should reference one or more configuration items.
The configuration items are modeled in the Configuration Management Database (CMDB).
