Knative uses a single shared autoscaler. This is, by default, the Knative Pod Autoscaler (KPA), which
provides fast, request-based autoscaling capabilities out of the box.
You can also configure Knative to use Horizontal Pod Autoscaler (HPA), or use your own autoscaler, by implementing the Pod Autoscaler custom resource.
You can also configure Knative to use Horizontal Pod Autoscaler (HPA), or use your own autoscaler, by creating a [controller](https://kubernetes.io/docs/concepts/architecture/controller/) (also referred to as a [reconciler](https://godoc.org/k8s.io/kubernetes/pkg/controller/volume/attachdetach/reconciler)) for the Pod Autoscaler custom resource.

You can implement your own Pod Autoscaler if the requirements of your workload cannot be covered by the KPA or HPA, for example if you want to use a more specialized autoscaling algorithm, or if you need to use a specialized set of metrics not supported by Knative out of the box.
To implement your own Pod Autoscaler, you can create a reconciler that operates on your own class of Pod Autoscaler.
To implement your own Pod Autoscaler, you must create a controller to handle your class of Pod Autoscaler.
To do this, you can copy a [Knative sample controller](https://github.com/knative/sample-controller) and modify its configuration to suit your desired use case.

Your reconciler should only reconcile PodAutoscaler resources with that target.

The informer setup of your controller might look like this:
