Exciting enhancements to the App Service Environment
You can now use an internal load balancer in conjunction with an Azure App Service Environment. You can also deploy an App Service Environment in a virtual network that uses the Azure Resource Manager deployment model. In addition, you can deploy intranet/line-of-business applications into your Azure virtual network in an App Service Environment.
These have been some of the most heavily requested features in the past year.
