Scaling of Cloud Service (Classic) via Powershell or Terraform

Question

It's not possible to deploy the Cloud Service (classic) via terraform, So I have used Arm Template and Deploy Cloud Service (Classic). Following is the code.

resource "azurerm_resource_group_template_deployment" "classicCloudService" {
  name                = "testSyedClassic"
  resource_group_name = var.resourceGroup
  deployment_mode     = "Incremental"
  template_content    = file("arm_template.json")
  tags                = local.resourceTags
}

Following is the ARM Template which I have used.

 {
        "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
      "contentVersion": "1.0.0.0",
        "parameters": {
          "dnsName": {
            "type": "string",
            "defaultValue": "testClassicSyed"
          },
          "location": {
            "type": "string",
            "defaultValue": "westeurope"
          }
        },
        "resources": [
          {
            "name": "[parameters('dnsName')]",
            "apiVersion": "2015-06-01",        
            "location": "[parameters('location')]",
            "type": "Microsoft.ClassicCompute/domainNames",
            "properties": {}
          }
        ],
        "outputs": {}
      }

As scaling options are missing in the ARM/TF Template. I want to scale like below, As this is only possible via Powershell. (As far as I know). But it's in old Azure Module.

CloudService

TaskWorkerRole: 1

WorkerRole1: 1

LongRunningTaskworkerRole: 1

DialogCloudService

TaskWorkerRole: 1

Webhook: 1

Set-AzureRole -ServiceName '<your_service_name>' -RoleName '<your_role_name>' -Slot <target_slot> -Count <desired_instances>

Can we use Set-AzRole or any other command to scale this? Or can we also do this via Terraform or Do we have any ARM Template for this?

No we can not use set-AzRole ,Because The Azure Resource Manager and classic deployment models represent two different ways of deploying and managing your Azure solutions. To achieve that we can use the below PowerShell cmdlts to scale out the roles.

Set-AzureRole -ServiceName '<your_service_name>' -RoleName '<your_role_name>' -Slot <target_slot> -Count <desired_instances>
