Cloud computing

What is IT infrastructure?

IT infrastructure are the components required to operate and manage enterprise IT environments. IT infrastructure can be deployed within a cloud computing system, or within an organization's own facilities.

These components include hardware, software, networking components, an operating system, and storage, all of which is used to deliver IT services and solutions. An organization’s IT infrastructure can be used internally for business operations or to provide external services or solutions for customers.

What are the components of IT infrastructure?


Hardware includes servers, datacenters, personal computers, routers, switches, and other equipment.

The facilities that house, cool, and power a datacenter could also be included as part of the infrastructure.


Software refers to the applications used by the business, such as web servers, content management systems, and the operating system (OS), like Linux®. The OS is responsible for managing system resources and hardware, and makes the connections between all of your software and the physical resources that do the work.


Interconnected network components enable network operations, management, and communication between internal and external systems. The network consists of internet connectivity, network enablement, firewalls and security, as well as hardware like routers, switches, and cables.

Types of IT infrastructure

Traditional infrastructure

With a traditional infrastructure, the components—like datacenters, storage, and other equipment—are all managed and owned by the business within their own facilities. Traditional infrastructure is often thought of as expensive to run and requires large amounts of hardware, like servers, as well as power and physical space.

Cloud infrastructure

Cloud infrastructure describes the components and resources needed for cloud computing. You can create a private cloud by building it yourself using resources dedicated solely to you, or you can use a public cloud by renting the cloud infrastructure from a cloud provider so you don’t have to set it up yourself.

Hyperconverged infrastructure

Hyperconverged infrastructure allows you to manage your compute, network, and storage resources from a single interface. With software-defined compute and storage bundled together, you can support more modern workloads with scalable architectures on industry-standard hardware.

Why partner with Red Hat for IT infrastructure 

Red Hat offers software and support for every enterprise IT need, from infrastructure to platforms, storage to containers, and management to automation. The result is a standardized platform across physical, virtual, private cloud, and public cloud environments, with solutions that work as well with one another as they do with your existing technologies and processes.

Simplicity is the key to a more efficient, secure IT ecosystem. By deploying an infrastructure built on our open source technologies, you can simplify your IT stack while still maintaining your ability to do whatever you want now, and prepare for where you want to go in the future.
