 2. For Azure to communicate between the resources that you create, a virtual network is needed. You can either create a new virtual network or use an existing one. In this example, you'll create a new virtual network at the same time that you create the application gateway. Application Gateway instances are created in separate subnets. You create two subnets in this example: One for the application gateway, and another for the backend servers.
