That's exactly what I meant in the post. Thank you for helping to clarify that. Jian Giacomo,

So strictly speaking SaaS is not equal to Cloud Computing. I would say that SaaS is a subset of Cloud Computing, as well as PaaS and IaaS. So strictly speaking SaaS is not equal to Cloud Computing.

The terms are not synonymous, but most examples of SaaS are also examples of Cloud Computing. SaaS (or any *aaS) is about business model and delivery. If I buy SaaS, I'm going to expect a very different experience than if I bought SaaP (software as a product). With SaaS, I expect the vendor will take provide the infrastructure for the offering, install it, manage it and support it... all on my behalf. I get to just use the software and not worry about major upfront investment. SaaS is something that business/management types should care about. Cloud computing is about abstraction and architecture. If I'm writing an app that uses cloud computing, some functions of my app are outsourced to a service that lives somewhere else on the Internet and abstracts away the underlying implementation details of providing that service. In this way, cloud computing is just an evolution of some long standing application design trends, just like client/server apps and n-tier distributed apps. Cloud computing is something that developer/systems types should care about. To illustrate my points, consider some specific examples... Is GMail or HotMail cloud computing? Yes, but not in a very sexy way. The only cloud aspect of it is that users connect over the Internet. Is GMail or HotMail SaaS? Yes, but also not in an interesting way. The product that they replace are free desktop email programs like Outlook Express. I'm sure there are other interesting examples. I suspect if we could come up with some good edge cases the true definition and limits of the terms would become more clear. > Is SaaS Cloud Computing?
