An "on-premises installation" refers to software or hardware that is set up and operated within a company's own physical location. This means that the organization is responsible for managing the infrastructure, including servers, storage, and networking equipment. On-premises solutions often require significant upfront investment and ongoing maintenance. In contrast to cloud-based services, on-premises installations provide organizations with greater control over their data and security. However, they may also require specialized IT staff to manage and troubleshoot issues. Many businesses choose on-premises installations for compliance reasons or to meet specific operational needs.
