    ARR Load Balancing Algorithm Selection

    Reply Contact

    While I am relatively new IIS7 and ARR, I have gotten my test config running with NLB and ARR each in high availability mode terminating multiple SSL's to multiple sites on the web farm.   For testing purposes, I currently have the ARR Server Farm running Round Robin Even Distribution and the NLB cluster for the ARR Servers running Multiple Host, Affinity None.

    What I am looking for is some guidance on the trade offs associated with each ARR load balancing algorithm.  I have not found a good article or forum post about the rules.

    I am primarily looking to scale data-driven SOAP web services across the Server Farm.

    Thanks in advance

    Here is a very quick/high level documentation on TechNet that describes that each of the algorithm does.  http://technet.microsoft.com/en-us/library/dd443524.aspx.

    You can infer the pros and cons of each algorithm based on how they are designed.  Of course, depending on your desired goal, different algorithm can meet your needs better than others.

    Thanks for the quick response.  I had not looked on TechNet.
