  • Load Balancing between 2 WWW servers in domain

    Hi,

    I have one DC - windows2003 and 2 WWW windows2008 web servers
    DC has 2 IPs: 1 legitimate - external IP and one internal IP.

    NAT is enabled by the DC.

    I would like to know how do I load balance between the 2 WWW windows2008 servers by the DC ?

    (Does the windows2008 DC makes this role/feature better ?)

    Thanks,
    Michael

    Enable and configure NLB on the Windows 2008 server.
    Point with NAT to the Virtual IP address of the NLB cluster.

    By the way, It's far from smart to expose your DC to the internet.

      Thanks,

      I am studying this configuration at this moment so the Domain is not really serving anyone, but I thank any remarks I can get from experienced users like your self.

      The Domain is a 2003 DC.

      Thanks,
      Michael

        Hi, another option would be round robin dns.

          This doesn't offer the advantages of clustering though.

            round robin isn't as intelligent as NLB but its easier to set up.

              NLB is easy enough to setup.

                With Round robin is the big disadvantage that when one node fails the clients still will be redirected to that node.

                  Less critical, using NLB requests will be split between the servers to maintain an even usage of server resources. Using round-robin DNS it is possible for one server to become overloaded, thus users would experience degraded performance.

                    No not on server resources but based on network resources for the node.
                    Server resources will only be monitored with clustering

                      When I say "server resources" I am including network bandwidth - pointless having a bells and whistles server, but communicating with it via RFC 1149

                        Yes that's the big disadvantage, apart from that it's good to go.

                        Also this if for two web servers, NLB might be a bit overkill.
