hi kkatta:
Take a look at the attached figure. The best thing for availability is to have an instance on each machine (i.e. horizontal scaling). If you are working with larger machines and want to have
multiple cluster instances, then use a naming convention similar to what you see in the figure.
The instances are arranged in string sorted order based on their instance name. If you have more than 10 instance, make sure to name them instance01 ... instance10, etc.
hope this helps
