It's a way narrower course than some of the descriptions suggest.
It's a good strategy these days to build one's business on top of a software core, with APIs for all major business functions and physical interface layers only when absolutely necessary. That's really the overall principle that I'm trying to communicate, along with examples in practice. Let's see if I end up being successful in this pedagogical goal!
