or maybe some other terminology would be better? lots of people get confused when you ask them to choose an instance, sometimes I think even the word “proxy”, “host”, or “hub” is simpler
the specific terms aren’t my point, just a discussion to see if we can come up with a better name
And an instance could be hosted on multiple servers.
I get what you mean but no one can check easily if two instances are on the same physical server. At least no one that requires a simplification in what we call instances. Unless I misunderstood what you meant.
