A Virtual Private Server (VPS) is not cloud computing while it is multitenant, it is neither high availability or scalable.
Shared hosting is typically not cloud computing, while shared hosting is multitenant and can be scalable, typically shared hosting is not high availability. There are an emerging number of Cloud Site plans that feature high availability and are competing with traditional shared plans.
Most SaaS companies use the cloud for delivery of their applications but just because a company offers a SaaS application doesn’t mean that its cloud, although it usually is.
There are a number of varieties in how cloud providers deliver and bill for their service, for example a number providers have adopted utility billing. The key here is cloud computing is about the product, not the packaging. That brings us full circle back to Ellison, his statement was prophetic as companies in every industry have tweaked their packaging and called their product cloud. When they should have changed the product and actually made it cloud.
