When you publish applications, you get greater administrative control over
application deployment with:
u
Selected user access. You publish applications for specific users and user
groups. By definition, an application you publish for a specific user group is
unavailable to other groups.
u
Enabled and disabled application access. You can temporarily restrict all
access to an application by disabling it. You can enable the application later to
return access to users. This capability is useful when you want to take an
application offline for maintenance.
u
Multiple-server application hosting. Application publishing, when used in
conjunction with Citrix Load Balancing Services, lets you direct ICA Client
connection requests to the least busy server in a farm of servers configured to
run an application.

Citrix server farms provide you with a flexible and robust way of deploying
applications to ICA Client users. Server farms let you centralize your control over
the application deployment process by grouping Citrix servers into a single
administrative unit. Citrix servers in a farm function together to make applications
easily available to your ICA Client users.
A server farm is a group of Citrix servers managed as a single entity and that
share some form of physical connection and a common base of user accounts.
After you place your servers in a server farm, you can publish applications on
servers in the farm for users in the common base of accounts. After starting
Program Neighborhood, a user logs in once, then sees an application set
containing each application configured for his or her specific user account or user
group.

When you publish an application, the server you specify to host the application
stores configuration information for the application in its registry. The collection
of registry entries governs the properties of the ICA connection including:
u
The application to run in the session
u
Users who can connect to the application
u
In the case of an application published in a server farm, client-side session
properties such as window size and colors and supported level of encryption,
audio, and video
