Scale and Performance Testing of Kubernetes

Diana Dvorkin - December 26, 2016
Managing thousands containers can be challenging, but if you want to know how Kubernetes will behave at scale we might be able to provide an answer. At KubeCon in Seattle, we shared the data we collected in our scale lab, which consists of 500 physical nodes. Using virtual machines, we can simulate up to 5000 Kubernetes minions running actual workloads, and our tests are designed to reveal how Kubernetes behaves while managing a complex application (in this case, OpenStack services) at large scale.

Have a look at the video to understand:
1. How Kubernetes performs rolling-updates, from a time and performance perspective
2. How fast one can roll-out containers on 500 nodes with specific constraints
3. How traffic flows between services, and what networking performance one should expect
4. How a single Service can facade 1000+ Pods with or without Autoscaler, and any limits involved
5. How many Services 1000-5000 Minions Kubernetes can support
6. How long it takes to deploy Pods for a single Service via Autoscaler to handle 1000 workloads
7. How long it takes to deploy Pods for a single Service via RC to handle 1000 workloads
