Service Mesh - CI/CD Glossary Definition
A service mesh manages secure, observable service-to-service traffic via proxies.
A service mesh is an infrastructure layer that manages service-to-service traffic (mutual TLS, retries, routing, observability) through proxies, without changing application code.
A service mesh handles networking concerns uniformly across services using sidecar proxies, offloading mutual TLS, retries, and telemetry from each application.
Relevance to CI
When CI deploys into a meshed cluster, jobs may need to inject or trust mesh certificates so smoke tests can reach services over mutual TLS.
