What Is Information Technology Infrastructure?
IT infrastructure includes hardware, software, network systems, facilities, and frameworks that supply IT services to business divisions and sustain their digital presence. Let’s explore what is information technology infrastructure.
IT infrastructure is becoming a mission-critical driver of business as digital transformation advances. The worldwide IT infrastructure industry is rising rapidly by $270.5 billion. A new window between 2020 and 2024 shows an 18% CAGR, boosted by COVID-19 and its IT effects. Information technology impacted the economy to enhance the development of business.
Every organization, from tiny firms to governments, from individual professionals to nations, requires IT infrastructure to function digitally. A mom-and-pop shop might operate without IT infrastructure, using manual and paper methods.
Consider modernizing the firm by taking card payments, providing online delivery, engaging in e-commerce, giving consumers WhatsApp updates, etc. IT infrastructure investment is required. Today, vital IT infrastructure may provide a company with an edge.

Wipro’s State of IT Infrastructure Report 2020 found that 75% of organizations want to modernize their infrastructure to include AI, ML, AR/VR, 5G, automation, and blockchain. 16% of IoT solutions are owned by IT infrastructure, not business units.
You need advanced IT infrastructure management solutions to keep up with your IT infrastructure’s complexity and adoption of new technology. Thus, AIOps are vital to infrastructure management for 6% of enterprises, with more in the pilot.
Another key IT infrastructure idea is in-house vs. managed operations. Small-to-mid-sized enterprises, especially non-digital natives like retail chains or hospitality groups, may engage with a third-party supplier to manage their IT infrastructure remotely with periodic site visits.
Large businesses and digital-native firms usually host and manage their IT operations internally with their staff and infrastructure. Recently, we discussed “What is communication in information technology?” Now you will get information on infrastructure and IT.
Why Does Information Technology Infrastructure Matter?
Business value platforms must keep up with technological advances. Otherwise, the company will lose market share and an edge. Cloud computing has evolved from a single destination to a continuum of capabilities and technologies.
This technology has never been more critical in helping organizations develop profitably, innovate, and operate responsibly and sustainably. Connectivity is needed everywhere, mainly due to the pandemic. IT infrastructure enables cloud-based business operations.
Furthermore, it lets companies create unique cloud-based experiences for customers and workers. However, IT departments are under pressure to boost innovation, speed to market, and financial flexibility. IT infrastructure and bandwidth are generally costly, hardware-focused, and inflexible.
IT Infrastructure Building Blocks: Main Aeras
Modern organizations of any size depend on four essential IT building elements. In this blog post, we will discuss information technology infrastructure. It includes the main areas as follows:

1. Hardware
Hardware includes all the elements, components, and equipment supporting an organization’s IT infrastructure. A mom-and-pop establishment may need a PC and printer. Mid-sized firms may utilize a set of PCs for their staff, one or two servers for their e-commerce/business site, and a security appliance.
Large companies utilize data centers to host their technological systems. Managed IT services let you rent infrastructure gear instead of buying it. Subcomponents of IT hardware include:
- Servers that stand alone.
- Personal computers and workstations, including laptops and POS systems.
- Physical router equipment.
- Peripherals include headphones, printers, collaboration gadgets, and more.
- Server rooms or data centers.
2. Software
Infrastructure software needs extra hardware as a host. Hardware and software make a complete IT infrastructure. A single PC with a software OS, productivity programs, security software, and an extensive multi-ecosystem configuration with multiple endpoints are included.
Windows, Linux, Mac OSes, containerized environments for app development, and remote cloud storage are all included. IT operations increasingly rely on software components instead of hardware.
Software-based network routers, OTT-deployed apps, and NGFWs may now replace physical disks, CDs, and hardware appliances. IT software subcomponents are:
- Operating system (OS) variations and distributions.
- Third-party applications for productivity, testing, and security.
- Desktop and web-based SaaS programs and perpetual licensing software.
- Developed in-house software, markets, and services.
- This includes application development, hosting, and production environments such as the cloud or containers.
Examples of software-based utilities include NGFW, routers, ANC software, connectors, and APIs.
3. Network
Technically, this is an optional IT infrastructure component, but current businesses need it. Local devices without networking systems cannot access the public or private Internet. The network is also required for IT activities such as cloud-based workflows, SaaS programs, and over-the-air distribution.
Networks comprise hardware and software components, which you configure to regulate user access. IT infrastructure management includes carrier licenses and telecom provider relationships for networking. Network subcomponents are:
- Private and public internet access cables include CAT 5/6/7 and fiber optics.
- Networking devices: firewalls, routers, and switches.
- Software components: SDN infrastructure, software-based firewalls, etc.
- Network configuration using application interfaces.
- Managed user access, network security, and bandwidth allotment via application interfaces.
- A web server serves as a center for networked IT operations.
Most infrastructure components are hardware or software. However, knowing these deeper Knowledge and technological options helps develop your IT ecosystem.
What Is Information Technology Infrastructure? IT Infrastructure Architecture Types
An IT infrastructure architecture designs and structures IT components for improved performance, easier administration, scalability, and cost-efficiency. Different IT infrastructure designs are available based on your company’s size and nature. The following IT infrastructure architectures exist.

1. Traditional Infrastructure
IT components are usually on-premises and siloed in conventional architecture. Most IT equipment and software are purchased, and an in-house staff runs the engines. IT teams vary by location, and business divisions, offices, and regions have siloed systems. This IT infrastructure design is seen in small-to-mid-sized, non-digital native companies.
2. Architecture Convergence
This IT infrastructure design addresses traditional infrastructure fragmentation. It integrates IT components into an efficient hub and creates integrated processes for visibility. Priority and business rules divide resources into “resource pools” that apps and processes share. Thanks to the cloud, converged IT infrastructure designs are simpler to consolidate, centralize, and distribute.
3. Composable Decentralized Infrastructure
This kind of convergent architecture leverages on-premise IT. New technology lets natural data centers act like virtual servers to assign resources on demand. Composable disaggregated infrastructure uses high-speed, low-latency networks for resource allocation and reduced downtime. For big, digital-native companies, an IT infrastructure design is evolving.
4. Hyperconverged System
Hyper-converged infrastructure leverages hypervisor-hosted software components to break down barriers and centralize administration. Software-defined storage, networking, and the hypervisor enable process-wide resource federation. IT infrastructure design employing COTS servers is typical.
5. IaaS infrastructure
Worth just $31.61 billion In 2019, IaaS is predicted to reach $202 billion by 2027, following the shift away from hardware-heavy IT infrastructure designs. Online IaaS services replace actual computing resources and components on public clouds or private hypervisors/virtual machines.
Although comparable to hyper-converged infrastructures, a third party offers and manages IT services using an IaaS, subscription-based licensing model.
6. Coded Infrastructure
This IT infrastructure management method lets you control the architecture using software or code instead of hardware configurations or UI settings. Strategically installed code in hardware and software IT components monitors processes, provides resources, enforces security, and more.
7. Cloud Architecture
Hosting IT infrastructure components in the cloud is becoming the norm. With options to migrate entirely to a public cloud, split operations between foundation and cloud environments, have your private cloud or use managed cloud services, most companies now use a hybrid cloud with cloud resources and private and many cloud suppliers.
