You can create your Cassandra cluster as a Private Network Cluster by selecting this add-on. This feature is available while using the service providers AWS or GCP. If you are running on Azure AZ, private network clusters are available if the cluster is running in your own cloud provider account. If you want to migrate existing clusters to a Private Network Cluster, you can contact our Support team. Refer to our support article on Private Network Clusters for more information.
Under the Application section for Creating a new Cluster, select Apache Cassandra as the base application and choose your service provider. Make sure to select Private Network Cluster under the Enterprise Features subsection.
Proceed with the cluster creation wizard according to your requirements. You can refer to our support article for Creating a new Cluster for more information.
After your Cluster has finished provisioning and is running, navigate to the Connection Info page for your cluster. The cluster will be in a private network cluster without a public IP. In this cluster, all inter-node communication within data-layer clusters (Cassandra, Kafka etc) occurs within a private network.
Therefore, any connection to this cluster, such as from a client application, requires the client application to be in a VPC which has network connectivity to the Private Network Cluster through VPC peering on AWS, GCP or VNet Peering for Azure AZ, or via a VPN, etc.
