yep, at most you might want 2 boxes for HA but you definitely don't have to start with that and it also depends on what you're doing.
I know some are going to argue that it's a slippery slope from that simple HA to DR and all the other complexities, and there's some truth in that, but that complexity can be controlled with explicit decision making. It's not obvious that a simple HA/DR story has to end up with modern day cloud architectures.
