Description

This template allows you to deploy a VM Scale Set of Linux VMs and create a new virtual network at the same time. These VMs have a custom script extension for customization and are behind a load balancer with NAT rules for SSH connections. This allows to specify the master node number and data node number, adapt to any primary / secondary architecture

Using new features

To enable Accelerated Networking feature ( SR-IOV ) which is a free feature, using the following example :

In network profile of VMSS , set "enableAcceleratedNetworking" to true, to have more information, please go to https://docs.microsoft.com/azure/virtual-network/create-vm-accelerated-networking-cli

If availability zone is available in your region, adding the following in your template to improve the availability of your VMSS :

      "zones": [
        "1",
        "2",
        "3"
      ]
}

Note that your Load Balancer should be STANDARD tier as well as your public IP ( if you're using it ), check here to know more about it : https://docs.microsoft.com/azure/load-balancer/load-balancer-standard-availability-zones
