# RAS Publishing Agents RAS Publishing Agent provides load balancing of published applications and desktops. A RAS Publishing Agent is automatically installed on a server on which you install Parallels Remote Application Server and is designated as the master Publishing Agent. Each site must have a master RAS Publishing Agent, but can have secondary agents added to it. The purpose of secondary agents is to ensure that users do not experience any interruption of the service due to a possible failure of the master RAS Publishing Agent. This chapter describes how to add RAS Publishing Agents to a site and how to configure them.
