Most businesses rely heavily on IT for daily operations, which calls for a robust and reliable IT infrastructure. In a published report, 57% of small businesses have expressed their need for an improved IT infrastructure to support their growing business needs. 

Many businesses need help figuring out where to start improving their IT infrastructure. This guide will tackle the basics of IT infrastructure, its components, benefits, and how to design a robust IT infrastructure. 

What is IT Infrastructure?

IT infrastructure consists of hardware, software, and networking components that serve as the foundation of technology in supporting IT systems and applications used in a business’s daily operations. IT infrastructure helps facilitate crucial tasks such as managing critical data, running software applications, facilitating seamless communication, and ensuring cybersecurity. 

Types of IT Infrastructure

IT infrastructure is categorized into three main components, namely hardware, software, and networks. 

  1. Hardware 

These are the physical components of your IT infrastructure that store, process, and transmit your business’s vital data. 

  • Servers: They store and manage data, applications, and resources that your organization needs.  
  • Workstations: Workstations are the computers used by your employees for day-to-day tasks. 
  • Networking Equipment: Routers and switches are some types of networking equipment that enable data communication within your organization. 
  1. Software

Software consists of necessary programs and applications that enable various functions and operations, such as operating systems, applications, and databases that manage and manipulate your business’s data.  

  • Operating Systems: Microsoft Windows, Apple macOS, and Linux are the foundation of your computers. 
  • Business Applications: Business applications such as Microsoft Office, Google Workspace, email systems, CRM systems, and communication systems are just some examples of applications that support day-to-day operations. 
  • Security Software: Antivirus, firewall, and intrusion detection software are essential to protect your IT infrastructure from cyber threats. 
  1. Networks

Networks connect hardware and software to communicate and facilitate communication between different components, allowing data to flow from one point to another.  

  • Local Area Network (LAN): LAN connects devices within a limited geographical area, such as an office. 
  • Wide Area Network (WAN): WAN connects multiple LANs across a broader geographical area, particularly beneficial for businesses with remote offices or employees. 
  • Internet Connectivity: Internet connectivity transmits data between your device or local network with the vast web of interconnected services, websites, cloud, and other services that make up the Internet. 

Benefits of a Robust IT Infrastructure

Having a robust IT infrastructure offers a host of benefits for your business, including: 

  1. Improved Efficiency: A robust IT infrastructure helps streamline processes by automating common tasks, including data entry and inventory management. It also optimizes workflows, allowing employees to focus on more strategic activities. 
  2. Increased Security: A secure IT infrastructure can protect your business against unauthorized access, theft, and loss — keeping sensitive business information secure. It helps you avoid costly data breaches and maintain your business’s reputation. 
  3. Reduce Downtime: A robust IT infrastructure can help prevent outages caused by hardware or software failures and, more importantly, its ability to recover swiftly from them. Minimizing technical issues and downtime keeps your business running smoothly. 
  4. Enhanced Scalability: A reliable IT infrastructure allows your operations to expand alongside your business and effortlessly accommodate your needs. It ensures your business remains agile in a constantly evolving business landscape.  
  5. Accessibility and Remote Work: Accessibility and remote work are integral aspects of a well-designed IT infrastructure. A well-designed IT infrastructure allows employees to work from any location, providing the flexibility required in today’s work environment. It can enhance productivity and adaptability within the organization, fostering a more efficient and connected workforce. 

How to Build a Strong IT Infrastructure for Your Business

  1. Assess Your Needs

Building a robust IT infrastructure requires careful planning as it will be the foundation of your operations. You should understand your business processes well to determine the type of IT infrastructure to support your business needs. Keep in mind these factors when designing your IT infrastructure: 

  • Size and complexity of your business 
  • Types of applications you use 
  • Security requirements 

Your IT infrastructure should be resilient, scalable, and easily adapt to future trends to avoid frequent overhauls. 

  1. Set a Budget

We would always want the best for our business, but the budget will always be one of the deciding factors in making decisions. Explore cost-effective solutions that align with your business needs. Prioritize essential components while considering potential future investments. Set a budget for your IT infrastructure project to ensure you can sustain the total cost of ownership (TCO), including maintenance, upgrades, and operational costs. 

  1. Choose the Right Hardware and Software

Ensure compatibility of your chosen hardware and software. Your IT infrastructure should be able to handle the demands of the application you use. It should be able to manage resource-intensive tasks without slowdowns or bottlenecks and is scalable, which will allow you to expand resources as needed to accommodate increased workloads. 

  1. Network Design and Security

While implementing security measures is essential, the overall design of your network also plays a pivotal role in its security. Optimize your network topology to meet both current and future requirements. Scalable and adaptable designs allow for growth while maintaining security.  

Don’t underestimate the power of robust security measures. Implement firewalls, antivirus solutions, and other security solutions to protect individual devices within your network. 

  1. Data Backup and Recovery Strategy

A well-designed IT infrastructure should have a reliable data backup and recovery strategy. It is a safety net, protecting your digital assets from threats like hardware failures, accidental deletions, malware attacks, and data corruption. Regular backups ensure your critical information is safe and allow your business to continue functioning smoothly in the event of data loss. 

  1. Implementation and Management

The next crucial step is implementing them and effectively overseeing your IT infrastructure. Hardware components, such as servers, routers, and workstations, should be deployed according to your network design. Install software applications and ensure they are correctly configured and updated to meet your organization’s changing needs. Hardware and software components should work seamlessly to promote efficient data flow and optimal system performance. 

  1. Monitoring and Maintenance

Monitoring and maintaining your IT infrastructure isn’t just a one-time thing; it should be done regularly to ensure your IT infrastructure’s longevity and optimal performance. Regular monitoring allows you to identify potential problems before they escalate into critical issues. With the use of monitoring tools, it helps you track the health and performance of your IT infrastructure components like hardware and software. 

Hardware components require routine maintenance. Also, regularly update software to address vulnerabilities and maintain a secure IT environment. 

Additional Tips: 

Here are some additional tips for small businesses that are building and maintaining their IT infrastructure: 

  • Start small and scale up as needed: You don’t need to invest in a complete IT infrastructure all at once. Start with the essentials and add components as your business grows. 
  • Consider cloud computing: Cloud computing can be a good option for organizations with little resources to manage their IT infrastructure. Cloud providers offer various IT services with flexible payment schemes to suit each business’s needs. 
  • Outsource IT support: If you don’t have the in-house expertise to manage your IT infrastructure, it is best to outsource IT support to a managed service provider (MSP). MSPs can provide various IT services, including network management, security, and help desk support.
