Infrastructure

IT Infrastructure: What Is It?

The collective elements required for the operation and management of enterprise IT services and IT environments are collectively referred to as information technology infrastructure, or IT infrastructure.

Reasons why IT infrastructure is crucial

Nearly every part of today’s organisations, from operations to products and services to the job of a single person, is powered by technology. Technology may be used to enhance communication, create efficiency, and boost production when it is correctly networked.

If an organization’s IT infrastructure is adaptable, dependable, and secure, it can assist in achieving its objectives and provide it a competitive edge in the marketplace. As an alternative, firms may experience connection, productivity, and security difficulties, such as system outages and breaches, if an IT infrastructure isn’t correctly built. Overall, whether a business is lucrative or not can depend on how well its infrastructure is implemented.

Using IT infrastructure, a business can:

Ensure that customers may access the company’s website and online store without interruption. Rapidly create and introduce solutions to the market. Gather information in real time to aid in decision-making. Boost workplace productivity.

An ideal IT environment

Although company demands and objectives influence how an IT infrastructure is set up, some objectives are common to all businesses. A firm will benefit from high-performance storage, a low-latency network, security, an efficient wide area network (WAN), virtualization, and zero downtime from the ideal infrastructure.

  • High-performance storage systems store and back up data and include a data recovery system in case of disasters.
  • Low-latency networks use enterprise-level infrastructure components to reduce the delay of data flow.
  • Secure infrastructures include systems that control information access and data availability. It can also safeguard a business against breaches and cyberattacks wherever the data resides, maintaining the customers’ trust.
  • WANs manage the network by prioritizing traffic and giving certain applications more or less bandwidth as needed.
  • Virtualization provides faster server provisioning, increases uptime, improves disaster recovery and saves energy.
  • Zero downtime aims to reduce disruptions to business operations and eliminates system downtime to keep costs down and profits up.

Types of infrastructure

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

Traditional infrastructure

The typical hardware and software elements of a traditional IT infrastructure include buildings, data centres, servers, networking hardware, desktop PCs, and corporate application software solutions. This infrastructure configuration typically demands more resources, such as power and space, than other forms of infrastructure. For private or company-only use, a traditional infrastructure is often established on-site.

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 servers maintained by a service provider at any or many geographical locations. Then, it divides and abstracts resources, like storage, to make them accessible to users almost anywhere an internet connection can be made. Because cloud infrastructure is often public, it’s usually referred to as a public cloud.

Infrastructure solutions

How do the parts of the IT infrastructure function?

Hardware and software are the two main categories of the interdependent elements that make up the components of IT infrastructure. Software, like an operating system, is used by hardware to function. Similarly, an operating system controls hardware and system resources. Using networking components, operating systems connect software applications with physical resources as well.

Hardware

Hardware components can include:

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


Software

Software components can include:

  • 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 comprised of switches, routers, hubs and servers. Switches connect network devices on local area networks (LAN) like routers, servers and other switches. 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.
