🧠 What's New?
Amazon ECS now offers native support for Blue/Green deployments — a long-awaited feature that allows teams to:
- ✅ Deploy new app versions alongside old ones
- ✅ Validate new versions before switching traffic
- ✅ Instantly rollback if something goes wrong
- ✅ Reduce risk, increase deployment speed
All of this is built into ECS — no more custom deployment scripts or third-party plugins required.
🎯 How It Works
ECS Blue/Green deployments now work with:
- ✅ Application Load Balancer (ALB)
- ✅ Network Load Balancer (NLB)
- ✅ ECS Service Connect
With the new ECS deployment type:
- ECS provisions the new task set (green) alongside the existing one (blue).
- You can run automated tests using lifecycle hooks before shifting production traffic.
- ECS shifts all or partial traffic to the green version based on your config.
- You can monitor the new version using CloudWatch alarms and the ECS deployment circuit breaker.
- If something goes wrong? Instantly rollback with zero downtime.
🔧 Key Features
