# Single Farm with VDI Hosts

VDI host pools are targeted for application and desktop publishing from hosts (full or linked clones) which are located in a single data center.

VDI hosts have the following advantages:

* Rapid deployment of a common supported desktop environment across the company's network using a single Windows 7, 8, or 10 desktop image for creating virtual machines (VMs) on a hypervisor.
* Centralized deployment of updates and changes to Windows VDI desktops — all you need to do is update a single image.
* In case of failure, the VDI desktops can be easily restored using a single image backup.
* Increased data security provides organizations with an extra layer of protection with dynamic security permissions. This is a security feature which prevents access to VDI without using Parallels RAS Client. After the session is established, Parallels RAS dynamically adds the user to the "Remote Desktop Users" group, granting permissions on logon and removing permissions on logoff. Even if a VDI virtual machine (VM) hostname or IP address is noted, users will not be able to connect to the VDI VM unless connection is setup from the Parallels Client.
