Application Networking on Kubernetes, where are we now?
summary
Claims that Envoy sidecars plus Istio provide observability, retries, mTLS and fine routing but require control-plane components and many per-pod proxies. Demonstrates EKS, Kubernetes Gateway API controller and Amazon VPC Lattice as concrete tools: the controller auto-creates service networks and exports/imports services, and Lattice routes across VPCs and accounts to EC2, EKS and Lambda without deploying sidecars. Presents this as a working alternative that removes sidecar maintenance while keeping layer‑7 routing, security and observability.
