In order to publish Citrix IMS applications, you must install Citrix Installation Management Services on your network. Citrix Installation Management Services performs remote unattended installation of applications on Citrix servers. Using IMS, you can simultaneously install an out-of-the-box application on all Citrix servers on your network from a single point without manual intervention. You can install applications on servers regardless of their physical locations, network connection type, or individual hardware setup.

Citrix IMS uses Published Application Manager to push application installations to your Citrix servers and also to uninstall those applications if necessary: publishing a Citrix IMS application causes each server configured to run the application to download and install the application while deleting a published IMS application causes each server configured to run the application to uninstall the application.

Published Application Manager supports publishing of an application on multiple servers if Citrix Load Balancing Services is installed on those servers.

When an ICA Client user connects to a published application configured to run on multiple servers, load balancing determines which server will run the application based on server load. The ICA Client contacts the master ICA Browser, which maintains a list of servers configured to run the published application, to find the address of a server containing the published application.
