2026-06-24

Amazon ECS service auto scaling now supports 20-second high-resolution CloudWatch metrics, enabling significantly faster response to workload changes with up to 76% faster scale-out and 72% faster end-to-end provisioning. It improves performance, reduces over-provisioning costs, and simplifies scaling configuration using target tracking policies across Fargate, EC2, and managed instances.
