It's called Quilkin: https://github.com/googleforgames/quilkin

There isn't. While the underlying technology is available in GKE with 1.2, the ability to seamlessly launch a multi-zone cluster doesn't yet exist. As mentioned in other comments, you could reverse engineer the GCE setup scripts and do this manually if you really wanted to.

+1. Thanks tsenart for the awesome load generator!

Correct. In addition, the source code used to run the demo is available on github at https://github.com/kubernetes/contrib/tree/master/scale-demo

Thanks, all clear now.

Tech Crunch incorrectly mentions that the service requires being added to a whitelist to use. It is available for anyone to try out immediately.

Oh interesting - you appear to be correct. You need to enable it through the APIs page then you have access.

confirmed I was able to do this (simply enable the API) on an existing project in the API Console

Oddly, I get a "only available for new customers" message, even after I enable the API.

That's because the link from the GKE page is for the free Google Cloud Platform trial ($300 credit), which is only available for new customers.

Ah, that would make sense.
