Create an application gateway using the Azure portal

You can use the Azure portal to create or manage application gateways. This quickstart shows you how to create network resources, backend servers, and an application gateway.

If you don't have an Azure subscription, create a free account before you begin.

Create an application gateway

A virtual network is needed for communication between the resources that you create. Two subnets are created in this example: one for the application gateway, and the other for the backend servers. You can create a virtual network at the same time that you create the application gateway.

  1. Click New found on the upper left-hand corner of the Azure portal.
  2. Select Networking and then select Application Gateway in the Featured list.
  3. Enter these values for the application gateway:

    • myAppGateway - for the name of the application gateway.
    • myResourceGroupAG - for the new resource group.

      Create new application gateway

  4. Accept the default values for the other settings and then click OK.

  5. Click Choose a virtual network, click Create new, and then enter these values for the virtual network:

    • myVNet - for the name of the virtual network.
    • - for the virtual network address space.
    • myAGSubnet - for the subnet name.
    • - for the subnet address space.

      Create virtual network

  6. Click OK to create the virtual network and subnet.

  7. Click Choose a public IP address, click Create new, and then enter the name of the public IP address. In this example, the public IP address is named myAGPublicIPAddress. Accept the default values for the other settings and then click OK.
  8. Accept the default values for the Listener configuration, leave the Web application firewall disabled, and then click OK.
  9. Review the settings on the summary page, and then click OK to create the virtual network, the public IP address, and the application gateway. It may take several minutes for the application gateway to be created, wait until the deployment finishes successfully before moving on to the next section.

Add a subnet

  1. Click All resources in the left-hand menu, and then click myVNet from the resources list.
  2. Click Subnets, and then click Subnet.

    Create subnet

  3. Enter myBackendSubnet for the name of the subnet and then click OK.

Create backend servers

In this example, you create two virtual machines to be used as backend servers for the application gateway. You also install IIS on the virtual machines to verify that the application gateway was successfully created.

Create a virtual machine

  1. Click New.
  2. Click Compute and then select Windows Server 2016 Datacenter in the Featured list.
  3. Enter these values for the virtual machine:

    • myVM - for the name of the virtual machine.
    • azureuser - for the administrator user name.
    • Azure123456! for the password.
    • Select Use existing, and then select myResourceGroupAG.
  4. Click OK.

  5. Select DS1_V2 for the size of the virtual machine, and click Select.
  6. Make sure that myVNet is selected for the virtual network and the subnet is myBackendSubnet.
  7. Click Disabled to disable boot diagnostics.
  8. Click OK, review the settings on the summary page, and then click Create.

Install IIS

  1. Open the interactive shell and make sure that it is set to PowerShell.

    Install custom extension

  2. Run the following command to install IIS on the virtual machine:

    Set-AzureRmVMExtension `
      -ResourceGroupName myResourceGroupAG `
      -ExtensionName IIS `
      -VMName myVM `
      -Publisher Microsoft.Compute `
      -ExtensionType CustomScriptExtension `
      -TypeHandlerVersion 1.4 `
      -SettingString '{"commandToExecute":"powershell Add-WindowsFeature Web-Server; powershell Add-Content -Path \"C:\\inetpub\\wwwroot\\Default.htm\" -Value $($env:computername)"}' `
      -Location EastUS
  3. Create a second virtual machine and install IIS using the steps that you just finished. Enter myVM2 for its name and for VMName in Set-AzureRmVMExtension.

Add backend servers

  1. Click All resources, and then click myAppGateway.
  2. Click Backend pools. A default pool was automatically created with the application gateway. Click appGatewayBackendPool.
  3. Click Add target to add each virtual machine that you created to the backend pool.

    Add backend servers

  4. Click Save.

Test the application gateway

  1. Find the public IP address for the application gateway on the Overview screen. Click All resources and then click myAGPublicIPAddress.

    Record application gateway public IP address

  2. Copy the public IP address, and then paste it into the address bar of your browser.

    Test application gateway

Clean up resources

When no longer needed, delete the resource group, application gateway, and all related resources. To do so, select the resource group that contains the application gateway and click Delete.

Next steps

In this quickstart, you created a resource group, network resources, and backend servers. You then used those resources to create an application gateway. To learn more about application gateways and their associated resources, continue to the how-to articles.
