Service Mesh and the future of networking
summary
Service mesh replaces in-app networking logic with a fleet of Envoy sidecar proxies per service plus a control plane (Istio Linkerd Consul) that pushes live configs; it delivers layer‑7 routing (percent canaries, header rules), distributed tracing and huge telemetry, fault injection and client retries, and identity based security using mutual TLS with ~30‑minute certificate rotation. It lets teams migrate VMs and multi‑cloud without VPNs by trusting mesh identities and applies policies by service identity rather than IP.
