I offer this as an afterthought without any expectations of replies to last week's latency discussion that focused on centralized vs. distributed, or one vs. many, data centers. While IMO the authors do not take into proper account the costs associated with network bandwidth and node provisioning, I thought it was nonetheless interesting due to the other factors they highlighted. There's nothing particularly correct here, merely some additional viewpoints on the subject that were not covered here earlier. Enjoy!
