Hi Kai. You mention

" In this setup each Virtual Server is simply configured with an /31 network mask (aka. two subsequent IPs for each VS) and each of the VE units is listening to just one of those /31 IPs (via additional Virtual Machine IPs)"

 

Is there a good document that details best practice about how to do this? Including config of any required load balancer or traffic manager?

Hi Jim,

 

afaik there is no such a guide available from F5.

 

You have basically to see the Azure based VEs the same way you would create a cluster on On-Prem Environments. Just the missing L2 capabilities of Azure are getting replaced with those /31 bit VS instances (in Azure IP-1 gets assigned to Unit-A and IP-2 gets assigned to Unit-B) and a Azure-LB in front of those IP-Pairs to perform Health-Monitoring which system is active and finally failover if needed.

 

Once a got it up an running you simply operate a usual and fully featured Active-Passive VE cluster with config and session state sync. There is basically no difference between OnPrem and Azure anymore…

 

Cheers, Kai
