There is another possibility that is probably much more widespread amongst AWS (and other cloud) customers. Here is the scenario: You are a small, hungry startup. No capital for servers. Cloud seems great. Then, big growth hits! Cloud seems even better - you may have the capital now, thanks to friendly VC/public investment/private equity, but you don't have the time to catch up. So, keep using cloud. Then, the now mid-sized company discovers one day that their use of the cloud is no longer economical, if it ever was. They are big enough to use a dedicated hardware in collocation or wholesale datacenter solution, with blended transit from some upstreams. But the cost to transition out of cloud is big, too. So, they might go with a hybrid strategy, at least for a few years. This happens all the time. Not saying Netflix is doing this, but lots of other folks are. It’s a trap that’s easy to fall into. Especially with rapid growth. - Dan
