Kubernetes networking has historically been split across two layers: the Container Network Interface (CNI), which handles pod-to-pod connectivity and network policy, and the service mesh, which adds application-layer features like mutual TLS, traffic routing, and observability. For years the common architecture looked like this: The rise of eBPF-based networking has started to collapse these layers….
