Gartner published recently an interesting paper: Productivity vs. Control: Cloud Application Platforms Must Split to Win. (The paper requires registration.)
The paper does a pretty good job covering the evolution that is taking place in the PaaS market toward a more open platform and compares between the two main categories: aPaaS (essentially a PaaS running as a service) and CEAP (Cloud Enabled Application Platform) which is the *P* out of PaaS that gives you the platform to build your own PaaS in private or public cloud.
