If you start running EC2 clusters, you're more in the "cloud storage" dominion and not really in the "self hosting" area anymore. Not everybody needs that and not everybody who does need it also realizes it before a major failure strikes out one of their machines and there is no working failover and their one admin is not reachable and when they finally reach him he has to be flown in, then they need to wait for replacement parts, which all in all delays recovery by several days.
