Definition
A dedicated networking layer (sidecar proxies) that handles service-to-service traffic transparently.
How it works
Proxies like Envoy run next to each service and take over retries, timeouts, mTLS, load balancing and observability, so application code doesn't reimplement them. A control plane (Istio, Linkerd) configures them centrally. Powerful at scale; real operational overhead for small fleets.
