Proxy server overview

You use a proxy server to control the connections that are allowed from your VPC or VNet and prevent unattended connections initiated from your environment.

Proxy servers can be used for:
  • FreeIPA backups: Backups created on an hourly basis are uploaded to cloud storage S3/ADLS Gen2.
  • Parcel downloads: Although CDP currently only supports pre-warmed images, it is a requirement to download parcels from archive.cloudera.com when an upgrade is performed.
  • Cluster Connectivity Manager (CCM): The autossh process that maintains the reverse SSH tunnel.

For our purposes, because we are addressing an environment with no internet setup, we will only use a proxy server when CCM is being used.
