Active / Passive with Azure Load Balancer

@CPO Thank you for reaching out to Microsoft Q&A. I understand that you want to know if Azure LB can do Active/Passive type load balancing.

Azure Load Balancer does not have any additional feature that can do Active/Passive.

Azure LB has no understanding of Active/Passive or Active/Active. From a Load Balancing point of view, it is simply a back end pool member answering the probe or not. It will be based on your configuration to make sure that you have an Active/Passive setup and that the Passive node does not respond to the probe and only the active one does. If the active responds to the probe as expected, then only it should handle the traffic.

However, this configuration would be possible by deploying a Traffic manager in your architecture. You can route traffic through Traffic manger based on priority method. Hope this helps.

Please let us know if you have any further questions and we will be glad to assist you further. Thank you!
