Amazon ECS Cluster Auto Scaling Now Available

ECS Cluster Auto Scaling uses the new ECS Capacity Provider construct in ECS, also launching today, to manage Amazon EC2 Auto Scaling Groups (ASG) on your behalf. Previously, ECS did not have the ability to directly manage the scaling of an ASG. Instead, you had to set up scaling policies on your ASG manually outside of ECS, and the metrics available for scaling did not account for the desired task count, only the tasks already running. With ECS Cluster Auto Scaling, the scaling policy of your ASG is managed by ECS through an ECS Capacity Provider. You can configure the Capacity Provider to enable managed scaling of the ASG, reserve excess capacity in the ASG, and also to manage termination of instances in the ASG. 

Amazon ECS Cluster Auto Scaling is available in all regions where ECS and AWS Auto Scaling are available. To get started, view our documentation.
