Hi NIck, yes, many thanks, that helps a lot to verify what I discovered later last night. Once I remembered Scalr DNS uses multiple entries for allocation (as oppose to how regular DNS works) it all made clear sense, i.e in the farm using an Nginx load balancer the DNS points to the Nginx role while the corresponding vhosts just point to the app role, in the single app farm everything (dns and vhosts) just point to the app role, easy...!
Thanks again for helping me out :-) Richard.
