Priority-based inbound traffic rule on private Azure load balancer

Gleb Kaplan 0

Hello, we need a setup where all traffic is routed to a primary VM, and if the health probe fails, then the traffic is routed to a secondary VM, which acts as a failover server, similarly as it is done in Traffic Manager. Can you please add an option of priority-based inbound traffic management on private Azure load balancer? The absence of this feature renders private LB useless for our purposes.

Thank you Kapil, I found that there is already a suggestion https://feedback.azure.com/d365community/idea/dda55d94-bde8-ec11-a81b-6045bd796569, which I just up-voted, however I am surprised to see that this demand is not popular, and yet Traffic Manager supports priority based routing out of the box, whereas private LB doesn't.

Hi Kapil, thank you for the summary. In my view I can consider the thread as solved, when the solution is provided. I don't see the confirmation of non-existence of the feature as a solution, I knew this feature does not exist when I opened the thread.

Kind Regards

Gleb

Hi, Gleb

You can't prioritise one endpoint over another - with Azure Load Balancer, as a workaround, you could have a Network Security Group rule assigned to the NIC of the other servers that deny traffic to the port you are after and then a Healthprobe alert that triggers automation to remove the block, but there will be downtime while the automation takes effect and the load balancer picks up the health probe change, or the alert starts the backend VMs instead.

Hi, I know that I cannot prioritize an endpoint, therefore I am requesting a new feature here. Thank you for the idea of a workaround, but it sounds rather complicated with a lot of moving parts, whereas it could be achieved by a simple rule, if it were supported by Azure.
