What is not cloud computing

Someone asked this question: "I would like to see... what is not cloud computing"

Here is my answer:

o Anything you don't bill and users work as they please.
Anything that you don't know who pays for what in a Data Center

o Anything that you have to reserve resources or have resource quota assigned to you, directly and indirectly
Anything that does not have elastic resources matching demand

o Anything that you have to load your apps and have headache to make them work.
Anything that does not have your application ready to be used as service
