# Private Node Pools

In IONOS Cloud Managed Kubernetes, a Private Node Pool is a dedicated set of nodes within a Kubernetes cluster that is isolated for the exclusive use of a specific user, application, or organization. Private node pools of a cluster are deployed in a private network behind a NAT Gateway to enable connectivity from the nodes to the public internet but not vice-versa.

You can create Kubernetes clusters for Private Node Pools using the [<mark style="color:blue;">Configuration Management Tools</mark>](/cloud/containers/managed-kubernetes/how-tos/download-kubeconfig-file.md) or directly using the [<mark style="color:blue;">IONOS Cloud API</mark>](https://api.ionos.com/docs/cloud/v6/#tag/Kubernetes/operation/k8sPost). By using the IONOS Cloud Kubernetes clusters for Private Node Pools, you can ensure the network traffic between your nodes and Kubernetes service stays on your private network only.
