SAP-C02 Design for New Solutions Practice Question
A company is designing a new microservices architecture on AWS. The company wants to use a service mesh to manage service-to-service communication, observability, and security. Which AWS service should the company use?
⚠ Common exam trap
Test-takers frequently confuse a service mesh (App Mesh) with an API gateway (API Gateway), but API Gateway is designed for external-facing API management, not for internal service-to-service traffic control and observability within a microservices mesh.

Correct answer & explanation
✓
AWS App Mesh
AWS App Mesh is a service mesh that provides application-level networking to manage service-to-service communication, observability (via metrics, logs, and traces), and security (via mTLS and fine-grained access policies) for microservices. It uses the Envoy proxy as a sidecar to intercept traffic, enabling features like traffic splitting, retries, and circuit breaking without modifying application code.
