  "summary": "The blue-green deployment strategy proved successful, ensuring zero downtime and instant rollback capability. However, a hidden cost emerged six weeks later, as the old environment remained running and incurring full infrastructure charges for six weeks. This anomaly occurred due to a lack of clear ownership and responsibilities post-deployment, leading to a \"dangerous\" open-ended rollback window. To prevent such issues, it's advised to tag every blue environment resource with a TTL (Time To Live) during launch and set up Cost Anomaly Detection alerts for resources exceeding their TTL. This approach ensures that decommissioning is integral to the deployment process, rather than a post-deployment cleanup task.",
