One of the main features of Knative is automatic scaling of replicas for an application to closely match incoming demand, including scaling applications to zero if no traffic is being received. Knative Serving enables this by default, using the Knative Pod Autoscaler (KPA). The Autoscaler component watches traffic flow to the application, and scales replicas up or down based on configured metrics.

Knative services default to using autoscaling settings that are suitable for the majority of use cases. However, some workloads may require a custom, more finely-tuned configuration. This guide provides information about configuration options that you can modify to fit the requirements of your workload.

For more information about autoscaling in Knative, see the Autoscaler types documentation.

For more information about which metrics can be used to control the Autoscaler, see the metrics documentation.
