For years, so-called thought leaders including myself have run off at the mouth about how IaaS is more of a stopgap, and eventually everything will be SaaS and PaaS. After all, why should you lovingly craft each installation yourself? Why should you build your own PaaS on IaaS with Puppet? Instead, the commoditization of computing will enable you to treat everything as either an application or a resource. PaaS must surely triumph.
