Prior to registering an environment, you should decide which region you would like to use.

A single Azure environment registered in CDP corresponds to a single VNet located in a specific region, and all the resources deployed by CDP on Azure are deployed into that VNet.

Typically, to speed up data access, you may want to deploy clusters into the region containing the ADLS Gen2 containers that you want to access for input and output data. Therefore, when selecting the region to use, you should consider where your data is located.

CDP requires that the ADLS Gen2 storage location provided during environment registration is in the same region as the region selected for the environment.

If you need to use multiple regions, you need to register multiple environments, one per region.
