One more thing... I understand offering options to your clients. That's a good thing. It IS possible to just go way overboard and confuse your clients with the differences in distros, and why you might want to use one over the other. Most people have never even heard of many of these, and some aren't even being embraced by their parent companies. This is absurd. Again, with Azure, there's no fancy service innuendos, they are named by what they do. They keep options and solutions simple.

Jumping back up on that horse, having been out of the tech business for a while. There's a couple cert paths that interest me as of recent, but for not it is either data science/engineering, artificial intelligence, and solutions architect. I have a few years of experience administering SharePoint, Office 365, Dynamics CRM, and have a goal and a plan. Let's see where this road takes me. It couldn't come at a better time; I'm all in baby.
