7 Components of IT Infrastructure

June 20, 2024

Feeling overwhelmed by the tech jargon thrown around your office like a footy on Grand Final day? Don't worry, you're not alone! Navigating the maze of IT infrastructure can feel like trying to find a decent flat white in another city—nearly impossible.

But don't worry; we're here to break it down for you in a way that even a Luddite could love. So grab a coffee, kick back, and let us guide you through the 7 critical infrastructure components that can keep your business running as smoothly as a well-oiled machine.

What is IT infrastructure?

Before we dive into the components, let's first define what IT infrastructure actually is. In simple terms, IT infrastructure refers to all the hardware, software, and network resources that are necessary for an organisation to deliver its IT services to both internal and external users.

Let's use an analogy to make it easier to understand. Think of IT infrastructure as the skeleton of your business, providing support and structure for everything else to function properly. Just like how a strong skeleton is essential for a human body to move and operate efficiently, a well-designed IT infrastructure is crucial for an organisation's operations.

Now that we have a better understanding of what IT infrastructure is let's take a closer look at its components.

IT infrastructure components.


Hardware refers to all the physical equipment used in an organisation's IT systems. This includes computers, servers, routers, switches, printers, and other devices necessary for day-to-day operations.

Having reliable hardware is essential for any business as it ensures that employees can perform their tasks efficiently without any technical difficulties or delays.


Software refers to the programs and applications that run on hardware devices. This can include operating systems, productivity tools, communication platforms, and specialised software for specific business functions.

Having a solid software infrastructure is crucial as it enables employees to perform their tasks effectively and efficiently. It also allows organisations to stay updated with the latest technology advancements, improving overall performance and productivity.

Data centre

A data centre is a physical facility that houses an organisation's IT infrastructure, including servers, storage devices, and networking equipment. It is responsible for storing, processing, and managing large amounts of data.

Having a well-designed and maintained data centre is essential for businesses as it ensures the security, accessibility, and reliability of their data.


The network is the backbone of any IT infrastructure. It refers to all the technologies and protocols used to connect different devices within an organisation's systems. This includes local area networks (LANs), wide area networks (WANs), routers, switches, firewalls, and other network components.

A robust network infrastructure allows employees to communicate with each other and efficiently access necessary resources. It also connects organisations with other businesses, partners, and customers worldwide.

Security systems

As technology continues to advance, protecting sensitive data and information has become more critical than ever. That's where security systems come in. These include firewalls, antivirus software, intrusion detection systems, and other security measures that protect an organisation's IT infrastructure from cyber threats.

Having a secure IT infrastructure is crucial for businesses of all sizes as it ensures the protection of confidential data and prevents costly data breaches.

Cloud services

Cloud computing has revolutionised how organisations store, access, and manage their data. Instead of relying solely on physical hardware and storage devices, cloud services allow businesses to store and access their data remotely over the internet.

Cloud services offer many benefits, such as scalability, flexibility, cost-effectiveness, and remote accessibility. It also reduces the need for physical hardware, making it an essential component of modern IT infrastructure.

IT support

Last but not least, having a reliable IT support team is crucial for maintaining and managing an organisation's IT infrastructure. This includes technical support, network management, system maintenance, and troubleshooting services.

Having dedicated IT support ensures that any technical issues are quickly resolved, minimising downtime and disruptions to business operations.

Tips for building your own IT infrastructure

Now that we've covered the essential components of IT infrastructure, let's leave you with some tips for building your own:

1. Assess your organisation's needs

Before investing in any IT infrastructure components, it's crucial to assess your organisation's specific needs and goals. This will help you determine which components are necessary and what type of infrastructure will best support your business operations.

2. Plan for scalability

Technology is constantly evolving, and so are the needs of businesses. When building your IT infrastructure, make sure to plan for future growth and scalability. This will save you time and money in the long run.

3. Invest in reliable hardware

As mentioned earlier, having reliable hardware is essential for smooth business operations. Don't cut corners when it comes to purchasing hardware; invest in quality equipment that can handle your organisation's workload.

4. Utilise cloud services

Incorporating cloud services into your IT infrastructure can provide many benefits, such as cost savings and increased versatility. Consider using a mix of on-premise and cloud-based solutions for the best results.

5. Keep security in mind

With cyber threats on the rise, it's crucial to prioritise security when building your IT infrastructure. Make sure to implement robust security measures and regularly update them to protect against potential attacks.

6. Regular maintenance is key

Just like how a well-oiled machine needs regular maintenance, so does your IT infrastructure. Make sure to schedule routine maintenance checks, backups, and updates to keep everything running smoothly.
