Quick Answer
In CI/CD pipelines: blue-green is configured by deploying a second environment and switching traffic via Ingress or load balancer update. Canary is configured with weighted traffic rules (Argo Rollouts, Istio VirtualService). Automated promotion: pipeline monitors metrics post-deploy, auto-promotes if below error threshold, auto-rollbacks if thresholds are breached.
Answer
Blue-green: Run old and new versions side-by-side; switch traffic once verified. Canary: Release new version to a small user segment first. Both minimize risk and downtime.
