on-premises

"On-premises" is a term used to describe IT infrastructure, hardware, and software applications that are hosted on-site, within an organization's physical location, as opposed to being hosted off-site in a cloud or remote data center[5]. This term is often used in contrast to cloud-based solutions, where data and applications are stored and run on remote servers[2].

On-premises solutions are managed and maintained by the organization's own IT team[4]. This gives the organization full control over its data and resources, which can be particularly beneficial for businesses with specific security, compliance, or customization needs[7]. For instance, industries such as banking and healthcare, which deal with confidential customer data and have more privacy concerns, often prefer on-premises hosting[7].

However, on-premises solutions also come with their own set of challenges. They require significant upfront costs for purchasing and setting up the necessary hardware and software[7]. They also necessitate regular maintenance and upgrades, which can be resource-intensive[4]. Furthermore, on-premises resources typically cannot be scaled up and down as easily as cloud-based resources[6].

In the context of software, on-premises software is installed and runs on computers within the premises of the person or organization using the software, rather than at a remote facility such as a server farm or cloud[9]. Examples of on-premises software include some applications by Microsoft or Adobe, which are hosted on the companies' own in-house servers[6].

In recent years, many organizations have been transitioning from on-premises solutions to cloud-based or hybrid solutions, which combine on-premises and cloud resources[5]. This shift is driven by factors such as the scalability and flexibility of cloud solutions, as well as the potential for cost savings over time[2]. However, the choice between on-premises and cloud-based solutions depends on a variety of factors, including the organization's business model, financial status, and business strategy[9].
