There are useful things like "heartbeat" which can transparently fail 
over from one machine to the next. They even take the IP address of the 
failed machine. A professional setup would have redundancy built in 
that way. I have run extremely busy load balancers that way and in the 
failover case everything is back to normal within seconds.
