Yeah, but the easiest way to learn a cloud provider's service is to read the TF provider's docs for the resource(s) in question. It helps to cut through the fluff and to get down to the essential elements of the offering.

Once you know how to provision the resource and all the switches and dials on it, you can then go find out what they do and how they work by readying the cloud platforms docs.

This MO works pretty well for me.
