Netflix is another example. A couple of thousand programmers and tens of thousands of VMs to build a top drawer e-commerce site. I built a drawer-below-top e-commerce site with twelve people in a year, and a third of them were muppets.

I interviewed at another well-capitalised streaming video place, and they also seemed overstaffed. They had a permission service that worked out what people could watch, based on purchases, subscriptions, and bundles. Something that's basically one SQL query. They had something like six people working on it full time.
