Managing Deployment Rollbacks

Overview

Implement and execute deployment rollback procedures for Kubernetes, ECS, Lambda, and cloud VM deployments. Detect failed deployments via health checks and error rate monitoring, then automatically or manually revert to the last known good version with minimal downtime and data integrity preservation.

Prerequisites

• kubectl configured with cluster access and permission to manage deployments
• Deployment history retained (Kubernetes revisionHistoryLimit, ECS task definition versions)
• Monitoring system tracking error rate, latency, and health check status (Prometheus, Datadog, CloudWatch)
• Previous deployment artifacts (container images, task definitions) still available in the registry
• Database migration strategy that supports backward compatibility (expand-contract pattern)
