An Azure Virtual Network (VNet) is needed for deploying CDP workloads into the customer’s cloud account. VNet is similar to a traditional network that you would operate in your own data center, but brings with it additional benefits of Azure's infrastructure such as scale, availability, and isolation.

Cloudera recommends that the VNet used for CDP is configured with the properties specified below:
  • The CIDR block for the VNet should be sufficiently large for supporting all the Data Hubs and data services that you intend to run. Refer to VNet and subnet planning to understand how to compute the CIDR block range.
  • In addition, you may want to ensure that the CIDR ranges assigned to the VNet do not overlap with any of your on-premise network CIDR ranges, as this may be a requirement for setting up connectivity from your on-premise network to the subnets.
