Defining your CDP Public Cloud data flow
To move data between cloud environments using NiFi site-to-site communication, you require a data flow in CDP Public Cloud that can receive data from the CDP Private Cloud Base data flow. To create this data flow, configure a process group, and both an input and output port.
You have prepared you clusters, set up your network configurations, and configured your truststores.

When you have completed your CDP Public Cloud data flow, proceed by configuring Apache Ranger to allow NiFi's site-to-site transmission.
