  • Round Robin .vs Windows Network Load Balancing

    What is the difference between DNS Round Robin and the Windows Network Load
    Balancing service? If I want to mirror two web servers for redundancy, what
    do I need to set up?

    Thanks,

    I guess there is no real difference in terms of which will benefit you most here. Round Robin will be the easier/quickest option to setup imo.

      Round robin doens't check the load on the network interfaces.
      It just passes on to the next one; for example
      Server1
      Server2
      server1
      server2
      etc.
      If server1 has a lot of traffic on his nic he still get more traffic onto his nic when round robin wants to.
      NLB gives some checkes on the load on the interfaces. Therefore it will make sure that that all servers has about the same amount of traffic.
      However sadly enough none of them will check the load of the machines.

      I would go for NLB. Just 1 (virtual) ipaddress where clients connect to, more balanced on the interfaces then round robin (none)
