Amazon ECS adds high-resolution metrics for faster service auto scaling
Amazon ECS now supports high-resolution (20-second) metrics for service auto scaling, enabling faster detection and response to load changes. This improvement reduces scale-out time by up to 76% and overall scaling time by up to 72%, leading to better application performance, cost optimization, and simpler configurations. The feature is available today for all ECS compute options and requires enabling high-resolution metrics in CloudWatch, which may incur additional costs.

Features (1) ›
- Enable high-resolution metrics for faster ECS service auto scaling
Amazon ECS service auto scaling now supports high-resolution (20-second) metrics, significantly reducing the time it takes to detect and respond to load changes. This leads to faster scale-out and provisioning times, improving application performance and reliability during demand surges.
Enhancements (2) ›
- Reduced scaling times and improved resource utilization
In benchmarks, scale-out trigger time improved from 363 to 86 seconds (76% faster), and total scale and provision time decreased from 386 to 109 seconds (72% faster). This allows for reduced baseline task counts without sacrificing performance, potentially lowering compute costs.
- Simplified scaling configuration
Target tracking with high-resolution metrics provides aggressive scaling behavior that previously required complex custom scaling policies. This new feature simplifies configuration, eliminating the need for custom engineering work.
Notes (1) ›
- Configuration and cost implications of high-resolution metrics
To use faster auto scaling, enable high-resolution metrics for your ECS service and configure a target tracking scaling policy. This feature is available for AWS Fargate, ECS Managed Instances, and Amazon EC2. While the feature itself is free, high-resolution CloudWatch metrics introduce additional costs.
