Problem Statement
Which benefit does adopting a service mesh bring when you have many micro-services operating in Kubernetes?
Explanation
In large micro-services environments a service mesh (like Istio or Linkerd) provides capabilities like mTLS, retries, traffic shifting (e.g., canary), and spans cross-service observability and routing. Interviewers often use this scenario to evaluate whether candidate knows how to scale micro-service architecture operationally.
