VMware Horizon Composer is a software service that works alongside the VMware vCenter and Horizon Connection Servers to deploy and manage linked clone desktops. Horizon Composer can be installed directly on the vCenter Server, or on a dedicated server.
Horizon Composer is only required if linked clone desktops will be deployed. Chapter 3, Implementing Horizon Composer, provides the information required to install and configure Horizon Composer.
Horizon Composer is not required when using Instant Clone desktops; it is only required if you are using linked clone desktops. The operation methods of Linked Clone and Instant Clone desktops are similar once they have been deployed, but the deployment process of these two desktops itself is quite different.
