Software Solutions to Load Balancing.

Windows NLB (Network Load Balancing) for 2003.
NLB's employ a "broadcast" approach similar to how layer 2 (OSI Model) hubs work..
When servers are part of an NLB cluster, they are participating in the sharing of a virtual IP.
When requests are made to that virtual IP all servers receive the request.
Responses occur from the only one member in the cluster; all others are dropped (aka-ignored).















All PC's are setup with IIS and the business web applications but only one IIS instance is used to handle the request via the NLB service.

NLB is configured using the Network Load Balancer User Interface or the Command Line tool (WLBS.exe).
