Amazon ECS adds Network Load Balancer support for Linear and Canary deployments

Amazon ECS Native Support for Linear and Canary Deployments with NLB

Amazon ECS now supports linear and canary deployment strategies for services using Network Load Balancers (NLB). This enables controlled traffic shifting during deployments, ideal for applications requiring TCP/UDP-based connections, low latency, long-lived connections, or static IP addresses.

These strategies allow for incremental traffic shifts, starting with a small percentage to validate changes before completing a rollout. They integrate with Amazon CloudWatch alarms to automatically stop or roll back deployments if issues are detected, providing additional confidence during updates.

What to do

• Select your NLB target groups, listener, and preferred deployment strategy in the ECS service configuration.
• Enable this for both new and existing ECS services in all AWS commercial and AWS GovCloud (US) Regions.
• Refer to the documentation for Amazon ECS linear deployments and Amazon ECS canary deployments.
