    The Vertical Pod Autoscaler (VPA) is useful when you can’t create more copies of your Pods, but you still need to handle more traffic.

    As an example, you can’t scale a database (easily) only by adding more Pods.

    A database might require sharding or configuring read-only replicas.

    But you can make a database handle more connections by increasing the memory and CPU available to it.

    Lastly, the Cluster Autoscaler (CA).

    When your cluster runs low on resources, the Cluster Autoscaler provision a new compute unit and adds it to the cluster.

    If there are too many empty nodes, the cluster autoscaler will remove them to reduce costs.
