To deploy Cloud Manager in an Azure US Gov region, you must download the Cloud Manager installer from the NetApp Support Site and install it on an existing CentOS 7.3 host.
For a list of supported Azure US Gov regions, see Cloud Volumes Global Regions.
Create a CentOS 7.3 virtual machine from the Azure Marketplace.
While Cloud Manager supports other operating systems, it only supports CentOS 7.3 in the Azure US Gov regions.
Managed Service Identities are not supported in the US Gov regions.
Cloud Manager is now ready to deploy Cloud Volumes ONTAP in an Azure US Gov region, just like any other region. However, you might want to perform additional setup first.
