What are the Various Components of a Complete IT Infrastructure?

Posted by Tom Clark on April 27th, 2023

IT infrastructure is a broad term that includes multiple components that work together to create that infrastructure. A complete IT infrastructure is one where all the necessary components are not only present but also capable of working in perfect synchronization with each other to deliver the expected results. Before we look at what the various components of a complete IT infrastructure are, it is important to first understand what the goals behind creating a complete IT infrastructure are.

Key Goals Behind Creating a Comprehensive IT Infrastructure

A comprehensive or complete IT infrastructure is created to:

  • Ensure network, data, and system security.
  • Minimize IT related issues and complaints.
  • Deliver proactive responses to burgeoning IT issues.
  • Deliver instant responses to IT-related complaints and provide quick resolutions.
  • Disaster detection, prevention, management, and recovery plans.
  • Instant notifications, alerts, and communications as needed.

These are just a few highlights, goals, and expectations that any good IT infrastructure within a company should be able to meet. Maintaining all standards mentioned here and the ones that were not can, unfortunately, be too expensive for a small or even medium-sized business to manage entirely on its own.

That is the reason why SMEs generally look for a competent managed services provider that meets the expectations mentioned above, rather than overspending on creating an in-house IT department that can meet all of them. That fact will become even more evident as we discuss the various components of a complete IT infrastructure.

Hardware

As per IBM, there are a few primary components that must come together to create the ideal infrastructure for Information Technology. These can be broadly classified under hardware, software, network, and facilities. Let’s get started with hardware first.

  • Servers
  • Data centers
  • Desktops and laptops
  • Internet connections
  • Routers
  • Switches

Software

The list of software components would be too vast and varied to be included comprehensively in any one list. They will vary depending on the nature of a specific business, its scale, requirements, sector, etc. Nevertheless, the following are the bare minimum software requirements that are applicable almost universally.

  • Operating System (OS)
  • Cloud/Web Servers
  • Content Management System (CMS)
  • Customer Relationship Management System (CRM)
  • Enterprise Resource Planning (ERP) Software
  • Business Analytics and Forecasting Applications
  • Payroll and Accounting Management Software

Facilities

Facilities refer to the space designated for housing IT hardware and networking components. For example, facilities include the various rooms and structures that are needed and dedicated to house and protect all IT networking and hardware components. The server room or the data center is a common example of a facility in IT infrastructure.

Network

Network refers to both hardware and software networks, which are the connections that keep systems interconnected within the IT infrastructure. Internet cables, routers, switches, extenders, LAN connections, Wi-Fi hubs, etc. all fall under Network.

However, that’s just the local network. The definition of network is much broader because it extends to online networks through cloud servers as well. In fact, online networking requirements are now a much bigger part of modern IT than local networks, although local networks still account for better security from external attacks.

All of the above components make up an IT infrastructure. Outsource this to a third-party MSP and your business will be a lot more secure.
