Previously limited in deployment methods with NLB, ECS now supports linear and canary deployment strategies enabling controlled traffic shifts during service updates. This benefits applications needing TCP/UDP support, low latency, or static IPs, such as gaming backends and real-time messaging.

The feature integrates with CloudWatch alarms to automate rollback or stop deployments upon detecting issues, increasing operational confidence. It is accessible through AWS Management Console, CLI, and Infrastructure-as-Code tools across all commercial and GovCloud AWS regions.
