Multi-Zone Clusters Inside and Out

Multi-zone clusters are a great tool for improving application reliability — and also a great way to spend a ton of cash. Why? What really happens when you set these things up? How do you use them effectively without bankrupting your whole organization? In this session, we'll dig into the nuts and bolts of what goes on under the hood of a multi-zone cluster, including what a zone is, what Kubernetes understands about zones, how zones affect routing, and why multi-zone clusters can drive costs up. We'll spend some time on Kubernetes' Topology Aware Routing, covering its advantages as well as its very real limitations. Finally, we'll dive into how you can influence Kubernetes' choices to take advantage of multi-zone clusters' reliability while containing costs.
