Quick Answer
Service mesh is an infrastructure layer that handles service-to-service communication. Deployed as sidecar proxies (Envoy) next to each service. Handles: mTLS encryption between services, traffic management (retries, timeouts, circuit breaking), observability (traces, metrics) - all without changing your app code. Istio and Linkerd are popular choices.
