The big thing they're crowing about is because you can spin something like this up quickly on demand in the G cloud. Most sites aren't remotely close to this artificial traffic pattern (1 packet request, 1 packet response). It's kinda cool from an L4 load balancing perspective that it's only one fault tolerant IP address. In terms of L4 LB throughput though, a single box with IPVS will happily do 1M pps.
