wrt horizontal scaling. Do recall that the motivation for this strategy by Google was cheap-as-possible servers that failed constantly. Back when they built racks using legos the problem was hardware reliability. They had to 'scale' horizontally for reliability (given cost constraints) as much as load. People have since bought into the marketing reasons for 'being in the cloud' and having 'infinite scalability' but that largely misses the point (and the pain) that caused many of these technologies and patterns to be developed in the first place. The best example of how to scale without buying into this pattern I know of is Stack Overflow.
