> I agree that many organisations will never get to the scale where they need it as a performance/data size measure, but you often will grow past the reliability level that's possible to achieve on a single node.

Many organisations have, for decades, exceptionally good reliability numbers using a backed-up/failed-over OneBigServer. Great reliability numbers did not suddenly appear only after 2012 when cloudiness took off.

I think you may be underestimating the reliability of OneBigServer.
