GKE Adds Native Prometheus Metrics for Autoscaling
🔔 Google Cloud announced built-in Prometheus metrics processing for GKE, enabling HPA to use PromQL queries directly via Google Managed Service for Prometheus. This removes the need for third-party adapters, reduces latency, and simplifies autoscaling configuration. The controller runs in the control plane and only deploys pods on nodes when PromQL metrics are actively requested, minimizing resource use. The feature is in preview with plans to add self-hosted Prometheus support before GA.
