What is a service mesh?
- AAn infrastructure layer managing service-to-service traffic — apps offload routing, security and telemetry
- BA message broker between services — requests are queued and delivered asynchronously by the platform
- CA Kubernetes network plugin — it assigns Pod IPs and wires the cluster's low-level connectivity
- DAn API gateway for internal APIs — a central proxy terminates and forwards every service call
Why this is the answer
A mesh moves cross-cutting communication concerns (routing, mTLS, metrics) into infrastructure proxies. It's not a broker — traffic stays synchronous and point-to-point; not a CNI, which handles IP-level connectivity; and unlike a central gateway, mesh proxies sit next to every workload.
