Information Technology (IT) infrastructure management – not to be confused with the broad responsibilities of IT management – is the administration and management of essential operational elements to effectively, efficiently, and proactively utilize technology, information, and data.
IT infrastructure is defined in ITIL as a combined set of hardware, software, networks, facilities, etc. (including all of the information technology related equipment) used to develop, test, deliver, monitor, control, or support IT services. Associated people, processes, and documentation are not part of IT Infrastructure.
Employees used to use desktop computers at the office and technology speed was not great. Nowadays each user connects to the network using multiple devices such as laptops, phones and tablets. Therefore, the IT infrastructure has to be available 24/7 with fast speed and have enough capacity to support a higher number of devices.
We configured and manage servers, storage and network devices. Increasingly, systems management tools are extending to support remote data centers, along with private and public cloud resources. Management tools are also making extensive use of automation and orchestration to improve efficiency, reduce errors and comply with established best practices or business objectives.
