What is IT infrastructure?

Information technology infrastructure, or IT infrastructure, refers to the combined components needed for the operation and management of enterprise IT services and IT environments.

Why is IT infrastructure important?

Technology powers nearly every aspect of today’s businesses, from an individual employee’s work to operations to goods and services. When properly networked, technology can be optimized to improve communication, create efficiencies and increase productivity.

If an IT infrastructure is flexible, reliable and secure, it can help an enterprise meet its goals and provide a competitive edge in the market. Alternatively, if an IT infrastructure isn’t properly implemented, businesses can face connectivity, productivity, and security issues, like system disruptions and breaches. Overall, having a properly implemented infrastructure can be a factor in whether a business is profitable or not.

With an IT infrastructure, a company can:

How do the components of IT infrastructure work?

The components of IT infrastructure are made up of interdependent elements, and the two core groups of components are hardware and software. Hardware uses software—like an operating system—to work. Likewise, an operating system manages system resources and hardware. Operating systems also connect software applications and physical resources using networking components..

Hardware

• Desktop computers
• Servers
• Data centers
• Hubs
• Routers
• Switches
• Facilities

Software Components

• Content management systems (CMS)
• Customer relationship management (CRM)
• Enterprise resource planning (ERP)
• Operating systems
• Web servers

Facilities

Facilities or physical plants provide space for networking hardware, servers and data centers. It also includes the network cabling in office buildings to connect components of an IT infrastructure together.

Network

Networks are composed of switches, routers, hubs and servers. Switches connect network devices like routers, servers and others on local area networks (LAN). Routers allow devices on different LANs to communicate and move packets between networks. Hubs connect multiple networking devices to act as a single component.

Server

A core hardware component needed for an enterprise IT infrastructure is a server. Servers are essentially computers that allow multiple users to access and share resources.

Server room/data center

Organizations house multiple servers in rooms called server rooms or data centers. Data centers are the core of most networks.

Types of infrastructure

The two primary types of IT infrastructure are traditional and cloud infrastructure.

Traditional infrastructure

A traditional IT infrastructure is made up of the usual hardware and software components: facilities, data centers, servers, networking hardware, desktop computers, and enterprise application software solutions. Typically, this infrastructure setup requires more power, physical space, and money than other infrastructure types. A traditional infrastructure is typically installed on-premises for company-only or private use.

Cloud infrastructure

A cloud computing IT infrastructure is similar to traditional infrastructure. However, end users can access the infrastructure via the internet, with the ability to use computing resources without installing on-premises through virtualization. Virtualization connects physical and virtual resources.

An Optimal IT Infrastructure

A robust IT infrastructure is the backbone of modern businesses, helping to ensure efficient operations, scalability, and security. While the specific infrastructure needs may differ from one organization to another, certain foundational elements are universal to achieving an optimized setup. The ideal infrastructure supports high-performance storage, low-latency networks, advanced security, optimized wide area network (WAN) management, virtualization, and minimal downtime to ensure business continuity and resilience.

• High-Performance Storage: A critical component of an optimal IT infrastructure, high-performance storage ensures that data is quickly accessible while remaining secure and resilient. Modern storage solutions include features like automated backups, data encryption, and fast retrieval capabilities, as well as robust disaster recovery systems that help prevent data loss in the event of unexpected incidents. Scalable storage systems also allow businesses to grow without requiring frequent overhauls.
• Low-Latency Networks: Low latency is essential for smooth communication and data transfer across systems. By reducing delays in data flow, low-latency networks enable real-time data access, which is critical for applications such as financial transactions, remote work, and customer-facing services. Enterprise-level infrastructure components like high-capacity switches, optimized routing paths, and modern fiber-optic networks help reduce latency, boosting productivity and customer satisfaction.
• Secure Infrastructure: Security is at the core of any IT infrastructure, safeguarding both business and customer data against breaches and cyber threats. Secure infrastructures incorporate advanced firewalls, intrusion detection systems, access controls, and encryption technologies that prevent unauthorized access. Regularly updated security protocols and compliance with regulatory standards (such as GDPR or HIPAA) not only protect data but also maintain trust and ensure businesses can operate in various industries with stringent data privacy laws.
• Optimized WAN: WAN optimization is essential for businesses with distributed teams or branch offices. An optimized WAN manages network traffic efficiently by prioritizing critical applications, balancing bandwidth, and enabling faster data transmission over long distances. WANs that incorporate Software-Defined WAN (SD-WAN) technology adapt to real-time conditions, making them more responsive and cost-effective for modern enterprises with global reach or hybrid cloud setups.
• Virtualization: Virtualization improves infrastructure flexibility by allowing multiple virtual machines (VMs) to run on a single physical server, maximizing resource use and enabling faster provisioning. It facilitates increased uptime, enhances disaster recovery capabilities, and reduces energy consumption by lowering the number of physical servers needed. Virtualization is a foundation for cloud environments, enabling businesses to scale services efficiently and adapt to changing demands without physical hardware constraints.
• Zero Downtime: Zero downtime strategies focus on minimizing or eliminating interruptions in service. This includes using failover systems, redundant data centers, and load balancing to maintain operations even during maintenance or unexpected failures. By reducing system outages, zero downtime infrastructures help businesses avoid costly disruptions, uphold service levels, and meet customer expectations for reliability and availability.
