What is the term for infrastructure or software that is hosted within an organization's own facilities?

The term for infrastructure or software that is hosted within an organization's own facilities is "on-premise." This refers to systems that are installed and run on the organization's own physical servers and hardware, allowing full control over the data, security, and maintenance of the infrastructure. Companies often choose an on-premise setup because it can offer higher levels of customizability and security, especially for sensitive data.

In contrast, cloud-based solutions involve hosting services off-site, often provided by third-party vendors and accessed via the internet. Hybrid systems are a mix of both on-premise and cloud-based solutions. Outsourcing refers to delegating certain business functions or services to external organizations, which does not imply hosting within the organization's own facilities. Understanding these distinctions is key in choosing the right infrastructure model depending on specific organizational needs and strategies.
