One of the most frequent questions we get at Zerto is “What do I need in Azure to use Zerto Virtual Replication (ZVR)?”
I find one of the easiest ways to visualize what Zerto is consuming in Azure is to pull up the Virtual Protection Groups (VPG) creation wizard in ZVR. For more on ZVR VPGs, see this great post from
I’ve got a vSphere site paired to the Zerto Cloud Appliance (ZCA) in Azure that I deployed from the Azure Marketplace. I’ve pulled up the VPG wizard and picked Azure as the target location for protection. This screenshot shows what ZVR is looking for in Azure in order to protect the VMs:
Looking at the left column we see very straightforward infrastructure requirements: VNet, Subnet, Network Security Group (NSG), Virtual Machine Series and Virtual Machine Size. Simply put, ZVR needs a network created in Azure, at least one subnet, a firewall (NSG), and you to tell it what size VM do you want to create.
For more flexibility of choice, the Virtual Machine Series and Virtual Machine Size can be different for testing and for production.
