IT Infrastructure refers to the entire stack of underlying elements required to deliver technology to an end-user. This includes hardware (servers, data storage, networking, converged systems), virtualization, management, automation and orchestration and the means to deliver the applications to the customer in the form of client systems (smartphones, laptops, tablets, thin clients, etc). Companies can drive real business results with IT Transformation.
All technology services from applications to business systems, digital records and smart products, require underlying infrastructure to be able to function. IT Infrastructure refers to the underlying technology stack that enables this service to be delivered.
The IT Infrastructure stack starts with hardware – compute capabilities provided by servers, data storage devices to store information and networking capabilities to allow the data to flow across the IT Infrastructure stack. This hardware layer can be built from individual components or acquired as a ready-to-run system, referred to as a converged system.
Most IT Infrastructure is virtualized into IT resource pools from which virtual machines, storage and networks are carved out for specific applications. These applications are what provide the end users the ability to perform their functions, from delivering ERP and payroll systems to running websites, cloud apps and internet delivered services.

Who uses IT Infrastructure, and why?
IT Infrastructure is necessary to deliver IT services to end-users. An efficient IT Infrastructure is easy to manage, agile to react to new user and business demands, able to scale up and down depending on demand and has full visibility and reporting into usage of the IT systems.
IT Infrastructure does not always need to be owned, nor does it need to reside within an organization’s premises. There are a plethora of cloud service providers who can deliver IT Infrastructure (Infrastructure-as-a-Service, or IaaS) with various payment models.
How IT Infrastructure works
IT Infrastructure delivers the backbone of technology services. Most IT Infrastructure is housed in data centers where vast amounts of compute, storage and networking capability can be accessed to host applications and technology services. Users can connect to the back-end IT systems using client-side IT Infrastructure such as smart phones, laptops and tablets that can connect to the data center using networking capabilities.
