Hi Folks,
Can anyone here please share some thoughts and comments of when to use Azure WAF or Azure Firewall?
I have already existing Azure ExpressRoute so my Azure VMs can ping my OnPremise servers, and vice versa.
My purpose here is to be able to securely publish Azure Web Application & API that is accessing the database on my OnPremise SQL server.
Thanks in advance.

I think you can have a look at this link:

What would be the difference between WAF and firewall IDPS? Would IDPS be enough?

For your question:
This is definitely a good approach to secure your app service if it is exposed to public internet.
Public Internet Users –connects via the internet--> Application gateway (WAF) –secure and protect --> App Service –gets the data from--> Local OnPremise SQL Database.
Hope this answers!
