Configuring Web Farms
Microsoft provides fault-tolerant or load-balancing software solutions for use with Microsoft Internet Information Server (IIS) and the InSight Publisher application server. A Web farm enables InSight Publisher to point to the URL of a server that distributes job requests to all active IRS servers in the Web farm. If one IRS servers fails, the Web farm continues to send requests to other active IRS servers.
To create a Web farm on a Windows server, an IT administrator installs IIS with Application Request Routing (ARR) and URL Rewrite Module. For more information, see the Microsoft tutorials at http://www.iis.net/learn/web-hosting/scenario-build-a-web-farm-with-iis-servers.
