IT infrastructure consists of the equipment, systems, software, and services used in common across an organization, regardless of mission/program/project. IT Infrastructure also serves as the foundation upon which mission/program/project-specific systems and capabilities are built. Approaches to provisioning of IT infrastructure vary across organizations, but commonly include capabilities such as Domain Name Server (DNS), Wide Area Network (WAN), and employee locator systems.
