What is the best approach to host multiple (lets say 5) sub domains on Azure Application Gateway?

How many rules, http settings, health probes and backend pools are needed to host subdomains of the same parent domain on the same application gateway deployment. Examples of using subdomains could be http://sub1.abc.com, http://sub2.example.com, http://app.example.com, api.example.com and so on. We are using azure app services (web apps and API) no VMs.

TIA,

Your help is highly appreciated.

Hi, some little on-topic trivia, you can use the domain example.org in documentation (and questions) knowing that it is reserved solely for this purpose, as abc.com is a real domain. More details here: iana.org/domains/reserved I've heard off some horror stories (albeit quite funny) of people using the "make believe" top level domain ".xxx" in documentation, whereas that is now a real domain of a subject matter they didn't intend to link to! – Alex KeySmith
I have edited the name of the domains to example – Coppernicus

For each subdomain, you need a Listener and a backend pool and a HTTPSettings. The current limit is 100 Listeners, 100 Backend pool, 100 Rules, 100 HTTP Settings per Application gateway.
