I have two different cloud services for CM and CD environment. In scalability setting we need to mention Publishing Instance (setting name is Publishing.PublishingInstance). Since I am using Cloud services for deployment, Post OS updates machine name keeps changing.
How we can set the value of publishing instance to make sure it will not be impacted even if machine name changes?
Environment Details :-
Sitecore Authoring - Cloud Service "A" with one web role instance
Sitecore Delivery - Cloud Service "B" with Two Web roles instance
Sitecore Version - Sitecore 8.1 update -2
Do we really need publishing instance if we have only one CM server?
