An example: if someone takes control of an internal apps server, it reaches the DB directly.
DB is the place, where your sensitive data resides.
So , firewall between your internal apps servers becomes a little unneeded here. At least for this case , as that someone will not try to break your apps nodes, that someone will directly go to db, because you have the listener port open between db and apps.. see..
