I am currently looking for a solution to achieve high availability for ADFS between a disaster recovery site in Azure and our core data centre on premise.
The ADFS is currently configured with split brain DNS so the internal users do not go through the WAP servers and go direct to the ADFS servers. I need to maintain this separation but in the event of a failure to my core site, i need the users to be redirected to Azure.
I am looking at Azure traffic manager to carry out the task, however, as the internal ADFS servers are not publicly accessible my understanding is that the probes will not work.
Has anybody got an experience with this scenario. Assistance would be greatly appreciated
