Hello,

I have servers in two different datacenters with each datacenter getting static IPs. What I would like to do is setup the servers as IIS7 servers and allowing them to failover from datacenter to datacenter with little (or preferably) no interruption. Servers on both sides are running Windows Server 2008 x64 with IIS7 (or 7.5 if needed). I am interested in how to point DNS traffic to the new datacenter without manual human intervention.

For example:

  • Datacenter A:
    • IP: 192.168.1.115
    • Servers: Server 2008 x64 w/ IIS 7


  • Datacenter B:
    • IP: 192.168.1.220
    • Servers: Server 2008 x64 w/ IIS 7


  • Other information:
    • Domain Name: Example.org
    • Domain DNS: 192.168.1.115

If Datacenter A connectivity went down (broken service line, etc.) how does the traffic know to route to Datacenter B on 192.168.1.220?

Thanks,

Scott
