 For Node autoscaling, Thundernetes can work with the open source [Kubernetes Cluster Autoscaler](https://github.com/kubernetes/autoscaler). To let Cluster Autoscaler be aware of the state of the Pods, Thundernetes adds the [safe-to-evict=false](https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md#what-types-of-pods-can-prevent-ca-from-removing-a-node) annotation to Active game server Pods and `safe-to-evict=true` to Pods in the Initializing or StandingBy state.
 
-We also recommend using the [overprovisioning feature](https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md#how-can-i-configure-overprovisioning-with-cluster-autoscaler) so you can spin up Nodes as soon as possible. Since the Cluster Autoscaler will create a new Node only when there are Pods in the Pending state and a new Node addition might take a couple of minutes, it might be desirable to have some Pods that just reserve resources with a negative PriorityClass, so these are the first ones that will end up on a Pending State.

 Each cloud provider has its own documentation for using the cluster autoscaler. If you are using Azure Kubernetes Service, you can easily enable cluster autoscaler using the documentation [here](https://docs.microsoft.com/azure/aks/cluster-autoscaler).
