Multi-cluster failover using Linkerd

Live on
Jul 14, 2022

Failover across clusters is a great way to improve the overall uptime and reliability of Kubernetes applications. While whole-cluster failover can be accomplished at the global ingress layer, failing over individual services is a little more difficult. During this session, Linkerd maintainer Eliza Weisman walks you through how to use Linkerd, the CNCF graduated service mesh, to enable traffic failover for individual services across clusters. Attendees will learn how to combine service mesh metrics, traffic shifting, and cross-cluster communication in a cohesive and automated way using purely open-source while preserving fundamental security guarantees such as mutual TLS.

Wanna give it a try? Here are the workshop slides and the GitHub repo. Happy meshing!
