RPath have posted a fun little video that summarizes what cloud computing is. It is focussed on the external cloud area, but it does give a simple and enjoyable outline of what Cloud Computing is and what some of the benefits are. So please watch the video below and if you are looking at an internal cloud just make the conversion in your head.
They get it right, virtualisation is the engine that drives both internal and external cloud infrastructures. This is where you should look first if you want to benefit from cloud computing (internal or external). Virtual servers are the first step, automating the virtualisation is the second step, simplifying and managing the expenses based on use is the thrid step. All of which can be done internally and externally.
