Depends which end of the scale you're at. At this end I bet hardly 
anyone rents because they have serious security issues to consider. 
Plus we get economies of scale doing it ourselves.

FWIW, we seem to get about 5 years out of a server, so compiler 
optimisations (more importantly gcc improvements) have made a 
difference to us.
