Azure Front Door Deployment using ARM Template

In this article, we will provision Azure Front Door using Arm Template. I have already created two Azure Web Apps which are running in two different regions i.e West Europe & South East Asia region. We will create & configure Azure Front Door to direct the traffic to these web apps.

Follow the below steps to deploy Azure Front Door:

1. Download this git repo and fill the parameters in azuredeploy.parameters.json as shown below:

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "frontDoorName": {
      "value": "ashishfrontdoortest"
    },
    "dynamicCompression": {
      "value": "Enabled"
    },
    "backendPools1": {
      "value": {
        "name": "backendpool1",
        "backends": [
          {
            "address": "ashishtest1.azurewebsites.net",
            "httpPort": 80,
            "httpsPort": 443,
            "weight": 50,
            "priority": 1,
            "enabledState": "Enabled"
          },
          {
            "address": "ashishtest2.azurewebsites.net",
            "httpPort": 80,
            "httpsPort": 443,
            "weight": 50,
            "priority": 2,
            "enabledState": "Enabled"
          }
        ]
      }
    }
  }
}

2. Run the below PowerShell command to provision the AFD.

Login-AzureRmAccount
$ResourceGroupName = "" #Enter Resource group Name
$AzuredeployFileURL="" #File path of azuredeploy.json
$AzuredeployParametersFile = "" #File path of azuredeploy.parameters.json
Set-AzureRmContext -SubscriptionId "" #Subscription ID
New-AzureRmResourceGroupDeployment -ResourceGroupName $ResourceGroupName -TemplateFile $AzuredeployFileURL -TemplateParameterFile $AzuredeployParametersFile

Once Azure front Door is deployed, go to browser and navigate the Frontend host URL of AFD. Your request will be routed to Azure Web App.

Go to Azure Portal to check the AFD configuration. Click on the Front Door Designer from left navigation bar and open Frontends/domains.

Here you can enable SESSION AFFINITY & WEB APPLICATION FIREWALL

Now open backend pools as illustrated below. Here you can update your backend pools configuration.

Last section is routing rule which maps your frontend host and a matching URL path pattern to a specific backend pool.

Here you can configure URL rewrite, Caching, Dynamic compression, Query String caching behavior etc.
