- Horizon View (aka VMware View) for virtual desktop delivery
- Horizon Mirage (aka VMware Mirage) for centralized (image) management of physical desktops or virtual desktops on Fusion (Mac or Linux) - NO support for VMware View virtual desktops for the initial release.
- Horizon Workspace (evolution of Horizon Application manager) providing access to applications and data on mobile device or computers
