## [Comparing HPA and KEDA: Choosing the Right Tool for Kubernetes Autoscaling](https://docs.rafay.co/blog/2025/05/20/comparing-hpa-and-keda-choosing-the-right-tool-for-kubernetes-autoscaling/)

In Kubernetes, autoscaling is key to ensuring application performance while managing infrastructure costs. Two powerful tools that help achieve this are the [**Horizontal Pod Autoscaler (HPA)**](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/) and [**Kubernetes Event-Driven Autoscaling (KEDA)**](https://keda.sh/). While they share the goal of scaling workloads, their approaches and capabilities are actually very different and distinct.

In this introductory blog, we will provide a bird's eye view of how they compare, and when you might choose one over the other.
