 Now you'll create network resources. In this step you're going to create a virtual network, one subnet 1 for Application Gateway, and one subnet for VMs. You also need to have a public IP to attach your Application Gateway to reach your web application from the internet.

 To avoid Azure charges, you should clean up unneeded resources. When you no longer need your scale set and other resources, delete the resource group and all its resources with [az group delete](/cli/azure/group). The `--no-wait` parameter returns control to the prompt without waiting for the operation to complete. The `--yes` parameter confirms that you wish to delete the resources without another prompt to do so. This tutorial cleans up resources for you.
