IT Infrastructure Solutions

The primary components of an IT Infrastructure are the physical systems such as hardware, storage, any kind of routers/switches and the building itself but also networks and software . In addition to these components, there is the need for “IT Infrastructure Security”. Security keeps the network and its devices safe in order to maintain the integrity within the overall infrastructure of the organization.

The IT Infrastructure is integral to the layers of the OSI Model. Without an IT Infrastructure, IT operations would not be possible. Everything from physical devices of the end user to the network in which they work on as well as the data they consume are not possible without the proper infrastructure in place in all the layers of the OSI model.

Specifically, the first three layers are directly involved with IT Infrastructure. The physical layer serves as the fundamental layer for hardware. The second and third layers (Data Link and Network), are essential for communication to and from hardware devices. Without this, networking is not possible. Therefore, in a sense the internet itself would not be possible.
