C10K for the modern world

Answering this question made me wonder: is there nice modern version of the famous C10K page? 5 years passed from the time it was updated and I'm sure there're advances in the field.

Perhaps current version would be called something like C1M pr开发者_运维问答oblem? ;)

In the modern world of things like distributed load-balancers and content distribution networks, I'm not sure that a single system having to be able to handle such a large number of concurrent connections is as big a deal. These days scalability is more about scaling out to distribute than scaling up to beef up your capabilities.
