The setup deploys the Broadcaster application across three Kubernetes clusters in Germany, Singapore, and the US West Coast, using DNS-based geo-routing via Azure Traffic Manager to direct users to the nearest cluster. Elixir's Erlang Distribution Protocol keeps all nodes synchronized across clusters. The post covers provisioning VMs on Hetzner Cloud, installing k3s without a CNI provider, configuring Cilium Cluster Mesh for cross-cluster endpoint slice synchronization, deploying Broadcaster as a StatefulSet behind STUNner, and validating the system with stream quality benchmarks showing significantly lower RTT and fewer freezes when connecting to the nearest cluster. ## Full article daily.dev links to this article rather than hosting it.
