Quite an expensive way to get reliability. How does an outfit like Google
achieve essentially 0% downtime? By running a swarm of half a million
commodity servers, that’s how. Every part has been built to the lowest
cost, except the power supply. And they discovered they can run their data
centres a little hot, to save on cooling costs, at the expense of a
slightly higher failure rate. Because if a few thousand servers are down
at any particular time, none of their users even notices.
