Infrastructure Infrastructure serves as the foundation and building blocks of an integrated IT solution. It is the hardware which supports Application Services (C.3.2) and IT Management Services (C.3.3); the software and services which enable that hardware to function; and the hardware, software, and services which allow for secure communication and interoperability between all business and application service components. Infrastructure services facilitate the development and maintenance of critical IT infrastructures required to support Federal government business operations. This section includes the technical framework components that make up integrated IT solutions. One or any combination of these components may be used to deliver IT solutions intended to perform a wide array of functions which allow agencies to deliver services to their customers (or users), whether internal or external, in an efficient and effective manner. Infrastructure includes hardware, software, licensing, technical support, and warranty services from third party sources, as well as technological refreshment and enhancements for that hardware and software. This section is aligned with the FEA/DoDEA Technical Reference Model (TRM) which describes these components using a vocabulary that is common throughout the entire Federal government. A detailed review of the TRM is provided in Section J, Attachment 5. Infrastructure includes complete life cycle support for all hardware, software, and services represented above, including planning, analysis, research and development, design, development, integration and testing, implementation, operations and maintenance, information assurance, and final disposition of these components. The services also include administration and help desk functions necessary to support the IT infrastructure (e.g., desktop support, network administration). Infrastructure components of an integrated IT solution can be categorized as follows:
