Adding Federated Services to Linkerd - Design Considerations and Debates

Federated Services is a new feature in Linkerd which allows a single Service to transparently span multiple Kubernetes clusters while remaining resilient to failures in one or more clusters -- without needing to change the application. In this lightning talk, Customer Success Engineer Phil Henderson discusses the design considerations and constraints navigated in the process of adding Federated Services to Linkerd. He covers how this design process took into account prior art (such as work in SIG-Multicluster), explored a variety of designs, and focused on delivering a solution that was tractable, clear, explicit, simple, and valuable to Linkerd users.
