Frontend:

We can add a custom domain binding and do CName entry in domain name server if required.

Backend:

Add the web Apps created in the both regions into this backend pool.

Routing Rule:

This routing rule takes care of routing the traffic based on the region from where we are calling the front door.

Accessing the application from India , request is routed to Australia as it is the nearest location.

Accessing the application from UK, request is routed to East US as it is the nearest location.
