Setting up and maintaining a portal farm | HCL Digital Experience
The term "farm" refers to a series of identically configured, stand-alone server instances. The stand-alone servers allow the farm to be increased or decreased without having to worry about complex cluster configurations or inter-server awareness. Server farms offer a simple way to build and maintain a highly scalable, highly available server environment. Creating the farm requires an established content subscriber, two or more installed instances of HCL Digital Experience, and a configured web server for load balancing. The farm documentation covers only the HTTP server plug-in. However, you can use any supported web server.
