Software as a Service (SaaS) is a form of cloud computing that delivers software functionality over a network, usually the internet.
- The software is running on a server(s) in a data center not physically in the same location as the user - it can be anywhere on the planet
- The user accesses the software using a network connection to the server. Again, the user can be anywhere on the planet and as long as they have a network connection to the server they can use the software's functionality

Wikipedia defines SaaS as follows: Software as a Service (SaaS; pronounced /sæs/) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted.[1]
Critique:
- Saas is a delivery model
- This delivery model can be priced any of a thousand ways without affecting the model itself
- Hence, the inclusion of licensing in the definition of Saas is superfluous
