Amazon ECS announces faster service auto scaling

Amazon ECS Service Auto Scaling Enhancements

Amazon ECS service auto scaling now detects and responds to load changes faster with support for high resolution (20-second) metrics and metric publishing optimizations. In AWS benchmarking tests, time to trigger scale-out improved from 363 seconds to 86 seconds (76% faster, 4.2x), and total time to scale and provision new tasks improved from 386 seconds to 109 seconds (72% faster, 3.5x). Faster service auto scaling also enables you to reduce baseline capacity and lower compute costs while maintaining service reliability and performance as workload demand fluctuates.

New Features

• Support for 20-second metric resolution for CPU and memory utilization metrics.
• Faster scaling signal detection with high-resolution metrics.

What to do

• Configure 20-second resolution for CPU or memory utilization metrics when creating or updating your ECS service.
• Use the AWS Console, CLI, CloudFormation, or AWS SDKs to configure target tracking policies.

This feature is available in all AWS commercial and AWS GovCloud (US) Regions, across all ECS compute options: AWS Fargate, Amazon ECS Managed Instances, and Amazon EC2. High-resolution metrics are subject to standard CloudWatch charges.
