Back in the early days of the AS/400 midrange system, the processor, memory, networking, and disk and tape storage hardware embodied in the system was by far the most costly part of that system, far outweighing the cost of the systems software that ran atop it. We don’t have the precise numbers at hand, but it was something like 85 percent hardware cost and 15 percent software cost.
Fast-forward a few decades, and the Moore’s Law improvements in every component in the hardware means that hardware is far less costly. But software doesn’t have a Moore’s Law scaling; in fact, …Read more
