At August 23 2016 VMware released vRealize Automation 7.1.
One of the most interesting new features is support for Azure. Currently the endpoint support for Azure is in beta as described in the comments of VMtoCloud.com . The vRA 7.1 support matrix still mentions Azure as not supported
To participate in the beta contact the program manager for vRA Pradnesh Patil.
vRealize Automation 7.1 supports Azure Resource Manager templates.
The new Azure endpoint has been tested by VMware with up to 20 Azure subscriptions. When you have over 20 subscriptions it should still work but VMware has not tested this.
