It wouldn’t be prudent to divulge the intellectual property (IP) details of how Azure App Services are configured in detail, but, right or wrong, I like to point to Azure Pack Web Sites (*) as the building block of Azure App Services.  However, keep in mind that Azure Stack is a more recent version of…
