A.  Add existing VMs through UI

In portal.azure.com -> All resources -> filter -> Select your ALB -> Backend Pools -> Add a virtual machine -> Select Availability Set -> Select VM

B.  Add existing VMs through resources.azure.com

Click on the “+” signs….

a.       Select :- subscriptions -> resourceGroups -> <your resource group> -> Microsoft.Network -> loadBalancers -> <your ALB>

b.       Enable “Read/Write”

c.       Click Edit

Under “backendAddressPools”: after provisioningState add/ammend backendIPConfigurations

          "provisioningState": "Succeeded",

          "backendIPConfigurations": [

            {

              "id": "/subscriptions/637156b4-7704-44f1-a19f-6bf607d6f499/resourceGroups/BasicIaaS/providers/Microsoft.Network/networkInterfaces/centoswebvm1959/ipConfigurations/ipconfig1"

            }

          ],

          "loadBalancingRules": [

d.       Click Put

e.       Check in the portal (or through powershell)

  Get-AzureRmLoadBalancer | Where-Object {$_.Name -like "*NRP*"} | ForEach-Object {$_.BackendAddressPools}
