Just look at the stack in that example you posted. It is a non trivial excercise and this guys has gone in deep. How many people are willing too or can..
And it doesn't talk about how robust it is. Its not a lot of fun performing rolling upgrades of cluster of rdbms backends whilst keeping everything up. How you do can be very dependant on the application structure It takes training, and resources. Yep it's a lot easier if you can fling virtual machines (ec2, vmware etc) around the place, but it does require careful design. The article doesn't say how many years it took to get it right, or what sort of failure rates he encountered during the early years.
