Types of IT infrastructure

The two basic categories of IT infrastructure deployed in the organizations are:

Traditional Infrastructure

The traditional IT infrastructure consists of software and hardware components, including data centres, servers, personal computers, and enterprise software solutions. This IT infrastructure is used for a single business entity and is set up on premises that enable the employees to access the needed applications and information. This IT infrastructure is more costly than others and requires additional space and power. Therefore, you need to have adequate financial resources if you want to opt for this conventional infrastructure. This infrastructure system needs to be updated frequently to increase the storage data and other facilities to expand it for other users.

Cloud Infrastructure

Cloud IT infrastructures are the resources and elements needed for cloud computing. The main difference between a traditional and cloud infrastructure is that the latter allows users to access the infrastructure through the internet and permits the organizations to use the IT infrastructure without having to go through the process of on-premises installation. Unlike traditional IT infrastructure, there is no need for traditional-like physical systems in a cloud infrastructure. The cloud service provider handles the physical infrastructure.

Components of IT infrastructure


Hardware refers to the physical component of the IT infrastructure, which consists of all the components needed to permit the devices and other machinery that create the infrastructure to work. It includes
