A traditional IT infrastructure is made up of the usual hardware and software components: facilities, data centers, servers, networking hardware desktop computers and enterprise application software solutions.

There are essentially 3 pieces to IT infrastructures: infrastructure hardware, software and networking.

The five stages of IT infrastructure evolution are as follows: the mainframe era, the personal computer era, the client/server era, the enterprise computing era, and the cloud and mobile computing era.

The IT infrastructure model illustrates the interrelationships between networks, as well as their hardware and structure. Thus, you can use it to entirely plan and document the network infrastructure.

IT infrastructure management service (IMS) is about administering and managing technology, information and data in a proactive way. Its scope ranges from the desktop to networking, storage, data, security and cloud-based services – not forgetting the people employed to keep everything working.

The role of IT infrastructure management is to administer and manage technology tools in proactive ways. This means being able to monitor for errors and issues, track fixes, and trace all errors back to initial sources.
