Nothing in this lesson makes you proficient in a second cloud provider — that was never the goal, and chasing it here would have meant a whole second hands-on track this course doesn't have room for. What it does is remove the "different subject" feeling: a virtual machine, an object store, a firewall rule, and a bill are the same four ideas everywhere, wearing different vendor names. Real proficiency on whichever one an actual job uses comes fast once the shape is already familiar — that's the entire bet this lesson is making.
