Application Auto Scaling target tracking can now be used to scale your Amazon AppStream 2.0 fleets. Target tracking allows you to dynamically scale your applications to automatically maintain a target metric. Using target tracking, AppStream 2.0 customers can simply specify a target capacity utilization metric for a fleet, and target tracking automatically increases or decreases the fleet capacity to maintain the target capacity utilization. Customers can configure target tracking policies for their AppStream 2.0 fleets via the AWS CLI, the AWS SDK, or AWS CloudFormation. To learn more, see Managing Fleet Scaling Using the AWS CLI.
