Pushing the envelope with Kubernetes
In this section, we will see how the Kubernetes team pushes Kubernetes to its limit. The numbers are quite telling, but some of the tools and techniques, such as Kubemark, are ingenious, and you may even use them to test your clusters. In the wild, there are some Kubernetes clusters with 3,000 nodes. Recently, at CERN, the OpenStack team achieved 2 million requests per second:

Mirantis conducted a performance and scaling test in their scaling lab where they deployed 5,000 Kubernetes nodes (in VMs) on 500 physical servers. More details here: http://bit.ly/2oijqQY.
At the end of this section you'll appreciate the effort and creativeness that goes into improving Kubernetes on a large scale, you will know how far you can push a single Kubernetes cluster and what performance to expect, and you'll get an inside look at some tools and techniques that can help...
