Advanced Topic 39 of 51 Distributed Systems & Cloud
Service Mesh
Infrastructure layer managing service-to-service traffic.
How it works
A mesh (Istio, Linkerd) injects sidecar proxies handling mTLS, retries, traffic splitting and telemetry without changing application code.
Where it is used
Large microservice fleets.
Common pitfall
Adds latency and operational complexity.
Where it fits in the course
Service Mesh is topic 39 of 51 in Distributed Systems & Cloud, rated Advanced. It follows API Gateway. The next topic is Docker.
