I’m trying to figure out a good way to organize this scenario.
I have 2 sets of hosts, call them general and reserved. If you are in a select group you should be able to choose which set your instances will deploy to. If you are not in this group your instances should always deploy to the general set of hosts.
Also I’d like to have both sets of hosts use the same datastores and networks. It does not seem that clusters are the right tool unless there isn’t a better choice.
