I\'m simply wondering if it is possible to create a private network on Azure and place a web app there? I know I can put VM\'s, SQL instances etc, but my question concern We
You need to create an App Service Environment (ASE) and deploy your web app there. Instructions on how to do this is available here.
Also, be advised that at this time, ASE can only be created in a v1 virtual network.
Absolutely - you need to set up Virtual Network or Hybrid Connection:
Reference #1: Connect to on-premises SQL Server from a web app in Azure App Service using Hybrid Connections
Reference #2: Integrate your app with an Azure Virtual Network
Reference #3: How to place your Web App into the existing Virtual Network (your situation, i guess)
And you will have the VPN/Virtual Network that will give your solution the continuous IPs space.
Earlier this was possible only for azure VM connected via private peering via expressroute.This is now possible with azure private link
