Anti-Complex Multicluster: Federated Services

Thursday, July 17, 2025

9 am PT | 12 pm ET | 6 pm CET

Linkerd 2.17 introduced federated Services, which allow a single Service to seamlessly span all your clusters in a multicluster setup, enabling advanced failover and easier application design. The magic of federated Services is that they act like single Services:  Linkerd handles all the hard parts of keeping the federated Service constantly up to date as clusters come and go, so your application doesn’t need to think about crossing clusters at all, and failover is completely automatic.

Join us for a deep dive into how federated Services work and how to best take advantage of them!

What you'll get out of this

  • Understand how federated Services work under the hood
  • See what new capabilities federated Services offer
  • Learn how federated Services can simplify application design

Getting Ready

This is a hands-on workshop, so it's important that you arrive prepared with a Kubernetes cluster (pretty much any kind will do!) and the Linkerd CLI installed on your machine! We'll use BEL 2.18, but edge releases starting with edge-25.4.4. will work just fine, too. Check out the BEL Getting Started Guide for specific instructions on how to set that up. (If you don't want to do the hands-on portion, you are welcome to just listen in. But it won't be as fun!)

Flynn is also the original author and a maintainer of the Emissary-ingress API gateway, also a CNCF project. Flynn's career in computing spans nearly forty years and runs the gamut from bringup on bare metal to distributed applications, with a common thread of communications and security throughout. He has spoken about Linkerd, Emissary-ingress, and other cloud native technologies at several conferences, including KubeCon/CloudNativeCon, DevOps Days, and the NYC Kubernetes meetup.
