Gradual deployments in Amazon ECS with linear and canary strategies

When deploying new application versions, you need confidence changes won’t impact customers. Amazon Elastic Container Service (Amazon ECS) now supports linear and canary deployment strategies, complementing built-in blue/green deployments. With linear deployments, you shift traffic in equal increments with a bake time between each shift. With canary deployments, you route a small percentage to the new revision and monitor before shifting the rest. Both strategies support Amazon CloudWatch alarms for failure detection and rollback, and lifecycle hooks for custom validation.
