Multi-cluster Failover Using Linkerd

June 29, 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 hands-on tutorial, Charles Pretzer, Linkerd team member, will walk attendees 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 pure open source, while preserving fundamental security guarantees such as mutual TLS.
