Honestly, computer systems should be approached and treated as though they have the complexity of the physical world. They're composed of a bunch of different parts, some moving, some distant, all accumulating all sorts of interesting bottlenecks and errors at the edges. The starting assumption that a given computer system is simple and ought to yield easily to analysis and modeling is a red flag in many situations.
