Cluster Connectivity Manager overview

Using Cluster Connectivity Manager (CCM), CDP can communicate with Data Lake and Data Hub workload clusters that are on private subnets. This functionality is available for CDP deployments on both AWS and Azure.

Communication takes place over private IPs without any inbound network access rules required. CDP requires that these clusters have outbound connections to AWS or Azure NLBs hosted in Cloudera's multi-cloud account. Workload clusters initiate an SSH tunnel to the CDP control plane, which is then used for all communication thereafter.

For example, CDP can communicate with clusters that are on private subnets with only private IPs without any additional network configuration or setup. However, CDP requires that these clusters have outbound connections to AWS or Azure NLBs hosted in the Cloudera's multi-cloud account.

You can use Replication Manager with your on-premise CDH clusters to assist with data migration and synchronization to cloud storage by first registering your cluster with Classic Cluster registration.
