🎙️ Candidate Opening & Architectural Context
""In enterprise CI/CD, you cannot rely on manual interventions; every rollback and promotion must be declarative. When addressing this question, I walk the interviewer through our production incident runbook: isolating the blast radius, checking diagnostic logs and metrics, and applying a safe fix.""

Production Solution & Architecture
Progressive delivery = controlled rollout with automated analysis. Use Argo Rollouts or Flagger. They send 10% traffic to new version, measure error rate and latency, automatically promote if metrics look good or rollback if they don't. No human intervention needed for standard deployments.
