Worker Groups is a new feature that was added in XenApp 6. A worker group is simply a collection of XenApp servers in the same farm. Worker groups allow a set of similar servers to be grouped together and managed as one.
“Worker” refers to the servers in a XenApp farm that host user sessions. Worker groups are closely related to the concept of application silos. Many XenApp farm designs group hosted applications into silos, where a silo consists of a single worker image cloned to multiple machines in order to meet the capacity needs of that set of applications. All workers in the silo share the same list of published applications and identical XenApp server settings. Worker groups streamline the creation of application silos by providing a way to synchronize the published applications and server settings across a set of XenApp servers.
Mark Butterly who is a Support Readiness Engineer based in our support offices in Dublin, Ireland recorded a series of videos providing an overview of the feature and how to implement it.
