In this post, I will be sharing the steps to create a new application gateway with multiple site hosting.

In this I have used WAF V2 as tier.

NOTE: The Standard_v2 and WAF_v2 tiers support availability zones. Changing from the WAF_v2 tier to the Standard_v2 tier is not supported

Application Gateway has two versions of the WAF sku: Application Gateway WAF_v1 and Application Gateway WAF_v2. WAF policy associations are only supported for the Application Gateway WAF_v2 sku.

To know more about WAF on Application gateway see waf on appgw

I want to demonstrate public access of 2 webservers so I have used frontend IP address as public

Atleast one Backend pool must be created.

Add a routing rule for the backend pool and select the desired backend targets, This will be a link to the frontend and backend . Also in the routing rule listener type select multisite and type as single or multiwildcard depending on your requirement. I this I have selected Multisite and single.

Validate the settings and hit create

Application gateway is created.
