On-premises (also called in-house) computing is an approach to IT infrastructure in which the individual or organisation takes full responsibility for all hardware and software, including the financing, installing, managing, updating, and replacing of each component. Additionally, the management of scaling, functions, configuration, security, and any other aspects of IT also falls to the company. On the other hand, there are no imposed limitations on what the organisation can do with its own IT, and it always has unfettered access to its own data.
In-house computing represents the highest level of responsibility as well as the most complete approach to data freedom. It also demands a significant amount of time, effort, and operating costs to effectively manage all the various aspects of IT infrastructure. Cloud computing exists to free up focus and essential resources, allowing businesses to outsource key services and capabilities to third-party providers on a pay-as-you-go basis.
