If I remove a vm (that is currently off) will the load balancer keep working sending all traffic to the other server?

I have two virtual machines, one if off and the traffic is being directed to the one that is working. I want to delete the virtual machine that is shut down, can I do that and will the load balancer keep sending traffic to the virtual machine that is running?

Thank You

    Hello @Chris Rotberg ,

    Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

    I understand that you would like to remove an already shut down VM from the Backend Pool of your Azure Load Balancer, which seems to have other VM running and healthy at the moment, and you want to ensure that the traffic would still be forwarding to the VM which is running. Is that correct?

    If so, there is not problem and you can remove it and it would not cause any down time. Since the VM is down so it not responding to the health probes anymore and it is not a part of the Load Balancer distribution, so all the traffic is already being balanced/distributed only between the others VMs on the Backend Pool (in your case, only one additional).

    • Health Probes:


    • Distribution Mode:


    • Load Balancing Algorithm:


    • Azure Monitor:


    Kindly let us know if the above helps or you need further assistance on this issue.
