Let's get started!

I remember in college, we were asked to do UML and User diagrams and we'd sigh. It was fun when doing but the background process of figuring out how things worked, was a headache (at least for me). Well, telling someone who's least interested to be there, to sit and draw "boxes" is a bad move already. But for someone trying to make sense of what's going on, I should have gone trying to understand. But I (we? Tell me, I'm not alone :') )figured it was a one time thing or something, which in hindsight was very dumb thing to think. The "IT" people's "ART" When I started my journey of figuring out Cloud Service Providers (CSPs) , I came across what are known as "architecture diagrams" pretty much early on and frequently. These are images which describe how various services (both third party and in-party) can be "put together and made to work" with various symbols and lines.

You don't have Linux but have Mac/Windows OS  Once upon a time Olden times (not like 500 years back. Maybe 20 years? Feel old? We are.), we installed Linux in the system and do the above. But it was neither easy nor quick (It is still an option, but one in many.). So, Virtual Machines were introduced where we could run another OS as if it was running on its own independent hardware, so as to allow time-sharing among several single-tasking operating systems ...
