Large-scale enterprises are really something to behold. Take one small example. A certain large company has cafeterias in many locations. Each of these cafeterias is like a small enterprise.

Someone has to build and maintain those servers as well. There's also a payment component and everything that comes along with that.

The cafeteria itself is a large scale enterprise, wholly enclosed inside the larger scale enterprise.
