The term infrastructure in an information technology (IT) context refers to an enterprise’s entire collection of hardware, software, networks, data centers, facilities and related equipment used to develop, test, operate, monitor, manage and/or support information technology services.
A company’s IT infrastructure includes the physical IT devices and products, but does not include the employees, documentation or processes used in operating and managing IT services.
From Infrastructures to Converged and Hyper-Converged Infrastructure Systems
Two infrastructure-related terms that have become increasingly relevant in recent years are converged infrastructure and hyper-converged infrastructure systems. The former refers to an optimized, tightly-integrated collection of IT components offered by a systems vendor that includes a variety of compute, storage, networking and virtualization resources.
Management of converged infrastructure resources is typically handled by a discrete hardware component that serves a singular purpose. While hyper-converged infrastructure systems are similar in nature to converged infrastructure systems, management of the resources is largely software-defined rather than being handled by one or more hardware components.
