But both integration tier and business tier run on the same machine
Who told you they can't be on same machine?
As far as
SCEA point of view
In the exam there are 2 different servers(Web Server) and (App Server) because exam started in the era when both servers were coming seperately.
But in today's scenario there is nothing like that.
And even though in the case of different AppServer both tiers on same machine.
