Howdy, There's another reason: if any of the three crashes or is attacked for whatever reason, the other two don't suffer. That may or may not make sense for your application.
For example, it's not unusual to have an admin console sit outside your firewall so that developers/admins can do their job from home. But you don't want the main/secure servers outside the firewall. Josh's scalability suggestion is also good.
