on-premise

In simple English

On-premise (also written as on-premises) describes a deployment model where an organization maintains and operates its own IT infrastructure. This contrasts with cloud-based solutions where a vendor manages the servers and data remotely. In tech companies, choosing on-premise deployment means the company has full control over the software, data, and security, but also bears responsibility for maintenance, updates, and hardware costs. Many enterprises prefer on-premise solutions for sensitive applications, legacy systems, or when they need complete customization and control. The term is commonly used in discussions about IT architecture, software licensing, and digital transformation initiatives.

Understand what on-premise software deployment means and how it differs from cloud solutions.

Real examples

Don't say this

Handle with care. Often confused with 'on premises' (physical location). On-premise refers to software deployed at a company's own location, not in the cloud.

✕We deployed the solution in the cloud, so it is on-premise.
✓We deployed the solution in the cloud, so it is cloud-based.— On-premise means hosted on the company's own servers, not in a cloud provider's data center.
✕The on-premise server is located in the building.
✓The on-premise infrastructure is located in the building.— On-premise is an adjective describing a deployment model, not just the physical location of hardware.
