Pattern 42 / INFRA
Use this when standardizing service-to-service behavior across many teams.
Service Mesh fits when standardizing service-to-service behavior across many teams. Mechanism: sidecar proxies mediate calls and provide mTLS, retries, telemetry, and traffic policy. Use it for large microservice fleets needing consistent networking and observability. The toll: operational complexity and another layer to debug.
Large microservice fleets needing consistent networking and observability.
Envoy sidecars enforcing mtls between services.
Describe the pressure first, then the mechanism, then the cost. That keeps the design grounded.
