Knowledge What is an IT Infrastructure: A Step-by-Step Guide | KDDI India

Information technology infrastructure, also known as IT infrastructure, can be defined as a collection of several components, including hardware, software, and network systems. Together, they enable IT service delivery to different business units of an organisation and help maintain its digital presence. In simple words, it provides the necessary foundation for things like communication, data management, and service delivery within an organisation. Further, the process of managing all the IT resources, systems, platforms, people, and environments is known as IT infrastructure management.

From small businesses to large enterprises, almost every kind of organisational unit needs an IT infrastructure to operate a digitally connected business. In this day and age, IT infrastructure serves no less than the backbone of modern businesses. A robust IT infrastructure can not only ensure smooth operation within the organisation but also help you gain an upper hand over your competitors.

There are several other benefits of a flexible and secure IT infrastructure, such as:

  • Providing an exceptional customer experience
  • Real-time data collection
  • Better decision-making
  • Enhanced employee productivity


There are two main types of IT infrastructure:

Traditional Infrastructure

A traditional IT infrastructure consists of conventional hardware and software components such as data centres, servers, desktop computers, etc. Due to the way this type of setup works, it needs a large amount of power and physical space. In addition to this, traditional IT infrastructures are relatively expensive as well. Here, everything is managed on-premises and is strictly for private use.

Cloud Infrastructure

As the name suggests, a cloud IT infrastructure has a complete focus on software components. It can be accessed via the internet from anywhere, anytime. To set up this kind of infrastructure, everything is done on the cloud with the help of physical servers. This cloud can be either private or public. There are several cloud providers, such as Alibaba, Amazon, Google, IBM, Microsoft, etc., that allow organisations to rent cloud space. Since it eliminates the need for bulky hardware and also requires less physical space, it is an inexpensive option.

Key Components

There are three main components used in an IT infrastructure:


In simple words, any component that has a physical presence can be defined as hardware. The type and size of hardware can vary from one IT infrastructure to another. It majorly depends on the specific requirements of the entity. If it is a large size enterprise, it will need multiple computers, smartphones, data centres, etc. to build an IT infrastructure. On the other hand, in the case of a small business, the only hardware requirements are a single computer and a physical router. Some of the commonly used hardware components include:

  • Standalone Servers
  • Desktops and laptops
  • Physical router equipment
  • Headphones
  • Printers
  • Mouse, keyboard, and other peripherals
  • Data centres or server rooms


Implementing RPA in an organisation requires good coordination between all employees involved in automation. Strong leadership is needed to guide teams through the process. Collaboration between teams helps complete the task accurately and build a system compatible with RPA, while IT involvement minimises risks and ensures security. Overall, careful planning and communication between departments are key for a successful RPA implementation.

    Network System

    Earlier, network systems used to be an optional component of an IT infrastructure. But now it has become one of the integral parts of any modern business environment. It enables network operations, management, and communication between all the internal and external systems. Without a reliable networking system, a setup cannot be accessed through the public or private internet. A network system usually consists of several sub-components, such as:

    • Different types of cables (CAT 5/6/7, fibre optics, etc.)
    • Firewalls
    • Routers
    • Switches
    • Software-based firewalls
    • SDN infrastructure, etc.
    • Application interfaces for network configuration, network security, bandwidth allocation, etc.
    • Web servers

    Things to Keep in Mind

    Here are a few tips to maximise the efficiency of an IT infrastructure:

    • Use hardware and software components that match the current and future requirements of your business.
    • Keep your software up-to-date, as outdated ones can lead to inefficiency in the overall system.
    • Always prefer cloud-based services, as they offer a great amount of flexibility and scalability.
    • Implement automation wherever you can. It not only saves a lot of time and effort but also leaves no room for human error.
    • Use efficient tools to monitor the systems. It helps identify and address a potential problem before it leads to a bigger issue.
    • Keep track of all the IT assets with the help of a centralised system.
    • Implement a robust cyber security plan to keep any kind of threat away and protect the data.
