New comment on "How do you explain cloud computing to your colleagues?"

LinkedIn Groups

Jose, that is a VERY good question. I think it has been answered here, but buried in all the retoric. The primary difference between Hosted Services and Cloud Services is Self-Service. By definition, a Cloud Service needs to be "immediately" available with little or no intervention by the hosting company. This, by the way, is pretty much the only differentiator. A cloud service has all the back-end work automated to spin up immediately with little or no human intervention. A non-cloud Hosting/Housing Service usually needs significant human intervention to setup an account and provision the service for you.

One way I sometimes think of it is "Can a setup my account at 2AM online with my preferences and be using it before 2:30AM the same day without calling someone?" If yes, then it might be able to be classified as a cloud service (there are 4 other parts to the definition - the biggest hurdle being scalability). If you can not say yes in normal circumstances, then it is not.
