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.
