I've now created my first cloud (virtual) machine. It is of course a special snowflake, because I had no desire to try to simultaneously learn this cloud vendor's web UI, terminology, etc and also some cloud machine automation setup. At least it's an extremely simple special snowflake and I kept notes (and off-machine copies of everything important).
I suspect that it is terribly set up and there are much better ways to do what I want, but meh. It's simple.
