From reading this ZDnet blog by Larry Dignan, Berstein analyst Jeff Lindsay seems to imply that Cloud Computing is essentially SaaS. This chart is shown.
By saying Open Office is a SaaS is stretching thing, as it is just a download of packages to install on desktops. This brings out questions about this chart. In addition, Lindsay did an analyst of the revenue from Amazon S3. However, he used 15 cents / GB for an entire quarter, whereas Amazon charges 15 cents / GB / month, so this raises more questions.
Additionally, folks from GoGrid and Mosso and others would likely say they offer cloud-computing, but they are not included in this analysis. The premise that cloud-computing = SaaS raises lots of questions.
