The admin/operator's time is usually seen as a fixed cost and keeping a 
machine working is not supposed to take unplanned time.  So, if you want 
to keep something running you really need to buy 3 of them in the first 
place.  One as primary in production, one as a backup, and one to be 
developing/testing the next version on.  In some cases you can replace 
the third one with a virtual setup, and you might be able to have one 
backup as a spare for more than one live server but you can't skimp much 
more than that.  Everything breaks, so if one thing breaking causes a 
big problem, it wasn't planned realistically.  This should be a 'swap in 
the backup' while you run extensive diagnostics or get a warranty repair 
on the broken thing.  And if you are running Centos the one thing you 
don't need is to pay for extra licenses to cover the backup/development 
instances.
