IT infrastructure
IT infrastructure describes all tangible and intangible goods that enable the operation of application software .
Definition taking into account the reference point
The IT infrastructure is the entirety of all buildings, communication services (network), machines ( hardware ) and programs ( software ), which are made available to a higher level through a subordinate level (Latin: infra "sub") for automated information processing. The higher level has no direct possibility of influencing the processes of the lower level; the planning authority for the processes remains with the lower level.
Examples are:
- For an operating system developer, only the computer (s) is “his” IT infrastructure, which he can use but not influence.
- For an application developer, the operating system is part of the IT infrastructure.
- For a "normal" user, from "his" perspective, all applications belong to the IT infrastructure, possibly also his telephone ( VoIP )
hardware
The IT infrastructure includes workstation computers as well as networks and servers . The IT infrastructure enables the use of digital media both internally and externally, for example in the form of a connection to the Internet .
software
The software that is available to employees on the workstation computers is also part of the IT infrastructure. It also includes network services offered by servers . Here, too, the offer is aimed at internal users ( file server , printer server , mail server , intranet , ...) as well as external users ( web server , mail server, FTP server) and external employees ( VPN ).
Consolidation of the IT infrastructure
The term “consolidation of the IT infrastructure” refers to the process of standardizing and merging (or even merging) server or desktop systems , applications, as well as databases or strategies. The goal is usually to simplify and make the IT infrastructure more flexible, often by reducing physical systems and replacing them with virtual systems .
