IIS Load Balancing

Posted on 2007-10-14

I have a need to have two virtual directories that point to two other app servers for the same application.  I want to be able to load balance between the two virtual directories (can be as simple as round robin).  I am using Microsoft Server 2003 and IIS 6.0.  Is this possible without an external piece of software or hardware like a content router?

    You can install a load balancing device but now your incurring cost, the drawback to dns is when you have a server down you can remove it but the problem is the time it takes for the dns to change is considered downtime.  The following option overcomes this problem.

    Very nice software can run on a linux box works great they have a free and pay version but it is very inexpensive and can tell if one of the servers is down and automatically reroute traffic.  It can also hold session data so it can follow sessions.

    Book about load balancing its a good book
