Federated Services: Straightforward Multicluster

Multicluster Kubernetes is becoming more and more common. Unfortunately, while it brings fascinating new opportunities to the table, fairly simple things like resilience and progressive delivery often become dramatically more complex when they need to span multiple clusters.

Federated services are a new Linkerd feature aimed at providing operational simplicity for multicluster. A federated service appears exactly the same from anywhere in your multicluster setup, while being able to reach everywhere in your multicluster setup, and Linkerd pushes the work of making that happen deep into the mesh so that the users of the mesh needn’t think about it: traffic will stay local where it can, route seamlessly across clusters where it can’t, and routing primitives just work as you expect. Watch this deep dive into what federated services are, how they work, and how to use them, and a live demo of what they can do!
