# AWS adds automatic scaling actions to CloudWatch PromQL alarms

_Published Tuesday, November 10, 2026 at 9:39 AM EST · Infrastructure · Latest · Tier 2 — Notable_

AWS says CloudWatch alarms using Prometheus Query Language can now trigger EC2 and Application Auto Scaling policies. Teams using OpenTelemetry metrics can use those metrics to adjust capacity rather than maintain separate classic metric alarms for scaling.

The release supports simple and step scaling. For step scaling, the distance beyond a query threshold determines which scaling step applies. Queries must return a single series, and target tracking policies are not supported. The feature is available wherever CloudWatch PromQL alarms operate, with standard CloudWatch alarm pricing.
