Need an analogy around vCO and vCloud Director?

We recently came across a nice little analogy around vCloud Director (vCD) and vCenter Orchestrator (vCO) from one of the folks over at NetApp on their blog. The article "What is vCloud Director, really?" cleverly equates vCD to the manager of an apartment complex and vCO to the maintenance man who does work for the manager and other managers (products). Please take a moment to learn more about vCO through this analogy and see what NetApp has to offer with their plugin for vCO!
