When your primary Kubernetes cluster goes dark, how quickly can you restore service? Most organizations rely on backup-and-restore strategies that leave applications unavailable for minutes or hours. Linkerd's federated services flip this paradigm by treating multiple clusters as a unified service fabric.

This session explores architectural patterns that leverage cross-cluster service discovery and intelligent traffic distribution to achieve true zero-downtime resilience. We'll demonstrate live failover scenarios, examine federation deployment models, and dive into the networking mechanics that make seamless disaster recovery possible—all while maintaining security boundaries and operational simplicity.
