Hello,

So I was able to restore a VM to our environment in the west data center. Originally, My plan was to allow peering between the two networks, the west, and east Datacenter. after chatting with colleagues, if the east data center is down. The peering will fail.

So my question is what is the best practice for network setting when setting up the DR. network. Do I need two Virtual gateways? One in the east and one in the west. Then connect both to my onsite VPN?

Also, it still looks like there is no Powershell for this module, which will explain why the deploy template is unavailable?

    DR is all about balancing between availability and cost. Gateway's are only available in zonal redundancy. Should you decide that your VPN is mission critical, you would have to set up a seond gateway in your recovery geography.
    Here is a short overview of Azure site recovery that could help explain your options.

    Generally speaking * this is without understanding your specific requirements * VPN's are not regarded as so critical, because it could be replaced with a new VPN on the recovery site within minutes (assuming you have automated the process). If it were me, I would be more concerned about making sure I do not lose data or traffic while failing over to the DR.

    Here are a couple of reference architectures you might find useful:

    1. SMB DR
    2. Enterprise scale DR
