What is IT infrastructure?

The definition of IT infrastructure is simply the many different components needed to run IT (information technology) or businesses that rely on IT to operate. These components include resources, composite hardware, software, and network services. IT infrastructure is extremely important in today’s world as more organizations are starting to utilize it to deliver services and solutions to their employees, customers, and partners. Get to know Walt Coulston, a digital infrastructure expert with an aim of moving toward sustainable practices.

That being said, there is a reliable services provider that offers outstanding IT infrastructure solutions in Dubai and Abu Dhabi. So, if you are from these areas and in need of infrastructure IT services, technopeak should be a frontier for you. It is a company dedicated to constructing infrastructure technology as well as solving tech-related issues.

What is IT infrastructure

Up to this point, we hope you now know what is an infrastructure in IT. Next, let us look at infrastructure computing. In computing, IT infrastructure consists of virtual and physical resources, which support the flow, processing, analysis, and storage of data. That brings us to the next section, which is the components of information technology infrastructure.

Components of IT Infrastructure

It is impossible to build infrastructure technology out of nothing. With that said, the entire ecosystem consists of software solutions, network connections, and various hardware. All these components complement each other and work together simultaneously.

The entire idea behind infrastructure IT is that it has led to improvement in communication between various devices such as tablets, desktop computers, cloud storage, and various servers. Well, improvement in communication helps beef up cyber security. Talking of cyber security, you can get such services in Dubai and Abu Dhabi simply by visiting

The components of infrastructure IT are pretty vast. Needless to say, we are only focusing on the main ones, which are hardware, software, facilities, network, server, and data center/server room.


Hardware is the foundation of IT infrastructure. It refers to the devices and physical components you need to organize infrastructure technology. The different types of hardware are:

  • Laptops
  • Smartphones, tablets, and other mobile devices
  • Internet hubs and routers
  • Desktop computers
  • Servers and data centers


This refers to different applications and programs that a business relies on to run smoothly. Software parts consist of:

  • Custom software for internal work
  • CMS (Content Management Systems)
  • Web servers
  • CRM (Customer Relationship Management)
  • Operating systems
  • ERP (Enterprise resource planning)


Also referred to as physical plants, facilities offer space for networking hardware, data centers, and servers. Facilities also consist of network cabling done in office buildings so components of IT infrastructure can be connected.


Networks comprise of routers, servers, hubs, and switches. Switches connect network devices on LAN (local area network). And these devices include servers, routers, and more. Routers, on the other hand, allow devices on various LANs to not just communicate but also move packets between networks. Last but not least, there are hubs that connect several networking devices, thereby, making them act as a single component.


Servers refer to computers, which allow several users to share and access resources. It is a core hardware component required for infrastructure technology.

Data Center/Server Room

Most networks heavily rely on data centers to work as expected. Well, data centers or server rooms are rooms where companies house multiple servers.

So, we have looked at what is an IT infrastructure as well as the components of infrastructure technology. Next, are the types of infrastructure IT.

Types of IT Infrastructure

There are two types of IT infrastructure: Traditional Infrastructure and Cloud-based Infrastructure.

Traditional Infrastructure

The key components of this type of infrastructure are software and hardware. One good thing about traditional IT infrastructure is that all equipment is under one roof, which makes it easier to access computing power and the necessary information. Other advantages of traditional infrastructure in IT are:

  • An opportunity to work with many different software types
  • You update both the infrastructure and the software, which means you get a chance to come across new technological solutions

Cloud-based Infrastructure

Today, most IT managers understand and know what is infrastructure in IT. The result is the rise in the popularity of cloud-based infrastructure. And the key reason cloud-based infrastructures are preferred is that they are flexible. Unlike the standard infrastructure, cloud infrastructure does not require you to have the equipment to support the infrastructure. That is because everything (software solutions, data storage, and servers) are stored in the cloud.

The following are some of the advantages of cloud-based infrastructure:

  • Cost-effective: You only pay for the specific service used. No need to spend money on upgrades, management, equipment, etc.
  • Outsourcing capabilities: All operations are outsourced to an organization that provides your company with a cloud-based structure.
  • Faster scalability: Cloud structures have no limits when it comes to storage space, which makes them perfect for a company aiming for rapid growth.


In a world where technology is constantly evolving, it is important that you understand the definition of IT infrastructure fully. But knowing what is an IT infrastructure and then stopping there is not enough. That is why we have also provided you with components as well as types of infrastructure technology.
