  • Dean Bushmiller thinks this is interesting:

The rest of this chapter discusses the differences between the three primary cloud computing areas: Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS), pronounced “sass,” “pass,” and “i-a-a-s,” respectively. Keep in mind that the field is new and changing. Rapid innovation of this kind causes the lines between IaaS, PaaS, and SaaS to blur, sometimes significantly. It won’t always be obvious whether something is PaaS or IaaS but the difference between them isn’t nearly as important as understanding the concepts of how to properly utilize these technologies.
