The big benefit of linux servers for most businesses is that they tend to be configure-once systems, where you set it up, verify it works then no further maintenance is needed beyond applying updates in line with your update schedule and downtime windows. Sure there will every once in a while be something that changes but far less than you see with Windows Server where some registry values stopped working with a recent windows update without warning so now you have to track down new registry values to recreate the behavior. That and tracking down why Windows decided to ignore all of your settings and reboot this time (and how to stop it again)
