On-Premises VS on premise - removing some confusion

There seems to be a lot of confusion regarding its spelling.

Here are examples of the correct usage:

1. This virtual appliance runs on premises.
2. We build and sell “On-Premises” virtual appliances.
3. Cloud computing will eventually eliminate on-premises solutions.
4. That argument is based on a false premise.

If you’re writing about something (such as a virtual appliance) which runs somewhere (such as your office), then the noun must be pluralized (see examples 1, 2 and 3), even if it refers to a single place.

A premise, also known as a statement, a proposition, or a theory, is not pluralized (see example 4) unless you’re referring to multiple premises.
