What Is IT Infrastructure?

IT infrastructure is an entire ecosystem of networks, hardware, and software. Each plays an important role as individual infrastructure components in an organization. In simple terms, it’s the interconnection between computers and gadgets, including things like printers, routers, hubs, and their communication via the internet and various cloud storage. Humans are not a part of this infrastructure. Based on this definition, we can distinguish three main types of interaction participants:


IT hardware includes computers, communications, and office equipment. Computers are conventionally divided into two classes: personal and high-performance, which are used to create large datastores and solve complex problems.


Basic software refers to the instrumental strategy of IT and includes operating systems (OS, programming languages, software environments, database management systems (DBMS), and more.


A network is the actual method of interaction between hardware and software by means of transmission over the Internet or internal systems.

What Are Some Features Of IT Infrastructure 

The components of IT infrastructure’s functions are almost limitless, as technological advances have reached virtually all business areas. Computer technology is everywhere, from agriculture to space exploration. It would be surprising to find an example of doing business where computer technology has not been introduced in some way, shape, or form. And the rapid development of the market tells that IT infrastructure will grow and develop even more. 

After all, thanks to technology, it’s possible to do business:


Computer systems are primarily introduced to accelerate working processes, to reduce the time from impulse to execution. You can compare this to the work of the neurons in the human brain.


Doing business with an IT infrastructure is environmentally friendly in terms of reducing CO2 emissions, reducing the use of paper and plastic, and the cost of maintaining it, especially if the actions are cloud based.


The development of IT infrastructure has really made it possible to hire workers remotely. With technology, it doesn’t matter what the person on the other side of the monitor looks like or where he or she is, what matters is professionalism.

Types Of IT Infrastructure

When thinking about the question; what is IT infrastructure? we should divide what it actually is into different types. Previously, the basic model for how the IT structure functioned was as follows:

Types of IT infrastructure

The technical equipment was localized, for example in the company’s office, and the people who used this equipment were tied to the location. In addition to the technical equipment, all the devices for storing and operating information were on physical carriers, also located where the technical equipment was. This method of operation is now considered traditional. We can not say that it is outdated, as it’s still the most secure type, but it’s not used everywhere. Most often this type of IT infrastructure is used by large corporations.

A more modern type of IT infrastructure is considered a cloud infrastructure. With the advancement of modern technology, with many people working remotely, it has become a lot more convenient and popular. With this type of infrastructure, there’s no need to be attached to a location or have an onsite facility. It’s more flexible and independent. Moreover, this type of infrastructure model is expected to grow as much as 46% by 2024.

Essentially the performance of these two types of IT infrastructure is not very different, the only variation is in the workflow itself and the cost of setting up and maintaining it.

How To Build Your Own IT Infrastructure

We have already defined an answer to the question; what is IT infrastructure?, so now, let’s talk about why you need it.

An IT infrastructure is the cornerstone necessary for the stability and development of any business, both offline and online. 

However, this does not mean that it’s necessary to invest astronomical sums in the development of an entire ecosystem; after all, for small and medium-sized businesses, it can be quite sufficient. Yet when designing it from the very beginning it’s necessary to think about what equipment and what systems can maintain the enterprise effectively and reliably over a long period of time, providing extra stimulus for development rather than hindering its activity because of deficiencies.

If a business owner doesn’t have his own development team or doesn’t have enough knowledge in the IT-sphere, of course, it’s better to turn to a profiled company or to an IT consultant to save time and money. 

With professional services, you can:

1. Define the goal and objectives for your unique IT infrastructure;

2. Foresee the potential growth and understand which type of infrastructure (traditional or cloud-based) will be appropriate for you; 

3. Configure and optimize software and hardware for uninterrupted operation, prevent system failures, and recover from failures;

4. Create and manage external resources: platforms, websites, applications, etc.;

5. Protect data on devices and cloud storage with special programs and applications.
