This is categorically incorrect. K8S will ultimately scale to N number of nodes. Within 2015, it will scale to 1K+ nodes, as per the roadmap. Being modeled after Google's Borg system, I encourage curious/interested folks to read at the recent Borg paper [0] which also outlines lessons learned in running Borg at Google for nearly 15 years and managing many millions of machines.

Calling that categorically incorrect is pretty disingenuous when we have Google engineers who are working on the project saying that it currently supports 100 nodes with ease, and that they /expect/ it to handle more in the (very near) future.

It might not be correct for much longer, but if it is the case now, how can you say it's categorically incorrect?

To clarify, this entire statement is categorically incorrect: "The only thing I'll add is that k8s isn't targeting the same scale as Mesos. Their current goal is to support up to 400-500 nodes, max."
