There are two ways to present applications to end-users with Horizon 7. There is traditional VDI, where the desktop exists as a virtual machine and applications are loaded as part of the base image, and there is RDSH (Remote Desktop Session Host), also referred to as session-based computing. RDSH allows applications installed on the RDS host to be presented to users using the Horizon Client, HTML Access or through VMware Workspace™ ONE™.
