A service mesh moves cross-cutting networking concerns (mTLS, retries, circuit breaking, traffic shifting, observability) out of application code and into an infrastructure layer. Istio is the most wi
Learning objectives

- Explain what mTLS actually guarantees, and why a service mesh is a practical way to achieve it cluster-wide.
- Explain the specific problem a service mesh solves for canary/traffic-splitting that plain Kubernetes Services can't.
