Cloud: Defining the Undefinable

Given that the definition of cloud is still somewhat fuzzy and the terminology is already spiraling (yes we have Private clouds, federated clouds and heavenly cloud cakes), I decided (for my own understanding), to map out where IaaS, PaaS and SaaS sit. The bit I was struggling with was that PaaS has multiple layers. Big thanks to Alexis for helping to organize my thoughts on this.



The cloud itself is just a category that groups more concrete concepts together.

The next step would be to drilling down into these layers and defining what services are required for each one.
