AWS – Amazon EC2 Auto Scaling introduces highly responsive scaling policies

Today, we are launching two new capabilities to EC2 Auto Scaling (ASG) that improve the responsiveness of Target Tracking scaling policies. Target Tracking now automatically adapts to the unique usage patterns of your individual applications, and can be configured to monitor high-resolution CloudWatch metrics to make more timely scaling decisions. With this release, you can enhance your application performance, and also maintain high utilization for your EC2 resources to save costs.

Scaling based on sub-minute CloudWatch metrics enables customers, with applications that have volatile demand patterns, like client-serving APIs, live streaming services, ecommerce websites, or on-demand data processing, reduce the time to detect and respond to changing demand. In addition, Target Tracking policies now self-tune their responsiveness, using historical usage data to determine the optimal balance between cost and performance for each application that saves customers’ time and effort.

Both these new features are available in select commercial regions, and Target Tracking policies will begin self-tuning once they have completed analyzing your application’s usage patterns. You can use Amazon Management Console, CLI, SDKs, and CloudFormation to update your Target Tracking configurations. Refer EC2 Auto Scaling user guide to learn more.
