Choosing between Amazon ECS Blue/Green Native or AWS CodeDeploy in AWS CDK

This article compares Amazon ECS native blue/green deployments (launched July 2025) with AWS CodeDeploy for zero-downtime ECS deployments in AWS CDK.

• ECS-native blue/green consolidates deployment logic into single service without CodeDeploy
• ECS-native performs all-at-once traffic shift with configurable bake time and rollback
• CodeDeploy supports canary and linear traffic shifting strategies for progressive exposure
• ECS-native recommended default for most teams; simpler operational footprint
• Choose CodeDeploy for advanced traffic shifting or AWS CodePipeline multi-stage workflows
• ECS-native includes lifecycle hooks, deployment alarms, and circuit breaker rollback
• CDK provides L2 support for ECS-native blue/green configuration

ECS-native blue/green is now the recommended approach for most deployments, offering simplicity and zero-downtime updates. Use CodeDeploy only for advanced traffic shifting or complex pipeline orchestration needs.
