+## Autoscaler for Kserve's Raw Deployment Mode
+
+KServe supports `RawDeployment` mode to enable `InferenceService` deployment with Kubernetes resources [`Deployment`](https://kubernetes.io/docs/concepts/workloads/controllers/deployment), [`Service`](https://kubernetes.io/docs/concepts/services-networking/service), [`Ingress`](https://kubernetes.io/docs/concepts/services-networking/ingress) and [`Horizontal Pod Autoscaler`](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale). Comparing to serverless deployment it unlocks Knative limitations such as mounting multiple volumes, on the other hand `Scale down and from Zero` is not supported in `RawDeployment` mode.
+
+### HPA in Raw Deployment
+
+When using Kserve with the `RawDeployment` mode, Knative is not installed. In this mode, if you deploy an `InferenceService`, Kserve uses **Kubernetes’ Horizontal Pod Autoscaler (HPA)** for autoscaling instead of **Knative Pod Autoscaler (KPA)**. For more information about Kserve's autoscaler, you can refer [`this`](https://kserve.github.io/website/master/modelserving/v1beta1/torchserve/#knative-autoscaler)

+
+### Disable HPA in Raw Deployment
+
+If you want to control the scaling of the deployment created by KServe inference service with an external tool like [`KEDA`](https://keda.sh/). You can disable KServe's creation of the **HPA** by replacing **external** value with autoscaler class annotaion that should be disable the creation of HPA
