Like any control-point solution, Apstra has its own set of terms that you need to learn and understand. I initially struggled with this, realizing after the fact that what was missing was context. To help myself, my customers, and anyone else learning Apstra for the first time, I created a single slide that showed how all of the different elements of an Apstra Blueprint (fabric) relate to each other.
This was years ago. I built the content, then moved onto the next thing. Today, someone asked me if this video was on my youtube channel...
Not a bad idea, actually!
