App Service Environment v2 release announcement
We are happy to announce an upgrade to the App Service Environment. The App Service Environment (ASE) is a powerful feature offering of the Azure App Service that gives network isolation and improved scale capabilities. It is essentially a deployment of the Azure App Service into a subnet of a customer’s Azure Virtual Network (VNet). While the feature gave customers what they were looking for in terms of network control and isolation, it was not as “PaaS like” as the App Service was normally.
