Quick Answer
Service mesh (Istio, Linkerd) handles observability and resilience at the infrastructure level without code changes. All inter-service traffic flows through Envoy sidecar proxies. The mesh automatically collects traces, metrics, and logs from every service call. It enforces retries, timeouts, and circuit breaking via config. mTLS encrypts all service-to-service communication.
Answer
Service mesh manages traffic, security, and observability transparently. Provides routing, load balancing, telemetry, and encryption. Examples: Istio, Linkerd, Consul Connect.
