Same approach : a server either works or it does not. The transition 
between working and not working may be expected or not expected. The 
solution is the same : use another machine to perform the work the now 
not working machine was doing. The big benefit of this approach is that 
you now do not need to worry about specific kinds of failure or 
individual components, including storage.

If it helps, think of this architecture as raid-1, but with the whole 
machine being the "drive" rather than individual storage devices.
