It point's out that I've equated SaaS to the extreme end of my analogy, and that's absolutely correct. As the author of the post points out (and correctly so) there is more of a continuum to SaaS architectures. I only meant to simplify the analogy to black and white so that I could get the point across. A fair discussion would be to distill my example from a binary form to a more analog one.

Just to elaborate on the point a bit: In the world of hosted software (you made the analogy with the on-premise model) and its various iterations - the ASP model maps/mapped well to the illustration of 400 vessels, each carrying a subset of passengers. Although you might lose one or two vessels on the way from point A to point B, a larger percentage of your passengers arrive safely at their destination. Because the SaaS model practically dictates the consolidation of your passenger bearing vessels into a mega-vessel... properly architecting resiliency cannot be understated.
