Crude? Use what you like to use, but you should keep one thing in mind:
If you don't know the software you are running in each and every detail,
how it behaves in each and every situation you can think of, it's a bad
idea to use it in a HA setup.
You don't want to be one of those admins that just configured something
in a few days, moved production stuff on it and fail to recover from a
split brain situation. Setting up a HA environment is something you do
in months, not days, at least if you want to do it right. There is so
much that can go wrong, and so much to learn. Keep it simple.
