What Is An IT Infrastructure And Its Components


The digital transformation is based on the corporate field, transforming how companies of all types and sizes assume their evolutionary process definitively.

As part of this change, the computerization of the activity requires the incorporation of computational systematization as an essential element that drives the development of the business activity, with IT Infrastructure being the name we give to the set of features that allow its operation.

What Is An IT Infrastructure?

We call IT Infrastructure the set of elements and components that make possible the operation of the technological activity of a company.

Also known as Technological Infrastructure or Information Infrastructure is a combination of devices and mechanisms whose structure will vary in each organization, adapting to its particular ICT needs.

The IT Infrastructure is already an integral part of most companies, both those that have computerized a large part of their operations and those that work only with a computer.

IT Infrastructure Components

To have a clearer picture of what IT Infrastructure is, nothing is more accessible than understanding what its components are.

You will have a more precise vision when you know all of them.


It is the first layer of an IT Infrastructure and refers to the physical elements the computing activity is carried out.

Examples of hardware can be computers, smartphones, peripherals, servers, and storage sources from which data is stored or managed.

In a very generic way, the hardware is each one of the solid units of the Computing Infrastructure.


The Software consists of the programs and applications that allow the hardware to function.

The most obvious is the Operating System (such as Windows, Linux, macOS, Android, or iOS) that allows a computer to function and run programs.

But the set of programs, such as Office, Chrome, or Photoshop, which make it possible to carry out complete activities, is also part of the Software.


The actual usefulness of an IT Infrastructure is based on the ability for all the company devices to be connected.

And also that these are connected to the outside.

Networks are the third element of the computing structure and are valued as the set of features that make it possible for all machines to connect.

Depending on the IT Infrastructure model that a company has, the networks can be internal and closed or open to the Internet.

At the same time, the internal connection can occur wirelessly or via a direct cable connection.

The Influence Of The Cloud

Until a few years ago, the most common IT Infrastructure model was the one that constituted all its components within the space owned by the company, so many organizations were forced to have a complete installation of computers and servers within the office.

With the standardization of the cloud as a model of computing resource consumption, we see how more and more companies derive part of their IT infrastructure to the cloud.

Due to the appearance of this technology, we find the following types of Technological Infrastructure:

Traditional IT Infrastructure Or On-Premise

Related to the type of device or connection established within the physical space.

IT Infrastructure In The Cloud

When the connection and operation of the machines is derived in the cloud through an IaaS provider from which the action is executed

Hyperconverged Or Hybrid IT Infrastructure

It is the most common. It is also usually the most efficient.

This computing infrastructure deposits part of its resources in the components in the physical space itself and another position in the cloud.

How The IT Infrastructure Is Managed

The administration of this type of system begins with the planning and definition of the model that best suits each company.

We are experts in the implementation of Information Systems, analyzing our clients’ needs and development possibilities.

But we are also experts in the administration and protection of your Technological Infrastructure.

That is why we indicate that there are two ways to manage it:

Risks For The Technological Infrastructure

The IT Infrastructure does not end when all the devices work and are perfectly linked.

We must bear in mind that a Computer System like this will also connect with the outside, causing threats from external agents to our network.

Cybersecurity or Computer Security is responsible for establishing all defense measures against possible risks.

In particular, Perimeter Security is responsible for keeping our entire IT Infrastructure safe from any subject that may attack from the outside.
