 The following sample creates a virtual network named TestVNet1 and three subnets, one called GatewaySubnet, one called FrontEnd, and one called Backend. When substituting values, it's important that you always name your gateway subnet specifically GatewaySubnet. If you name it something else, your gateway creation fails.
