The term VDI, or virtual desktop infrastructure, describes a virtual computing environment in which a single server hosts multiple desktop platforms, and users gain access to their desktops using remote access protocols. In environments where desktop virtualization solutions are deployed in a VDI, these solutions effectively replace both of the following:
- The traditional hardware-based server-client model that is found in many organizations that have not yet adopted a desktop virtualization strategy
- The server-client model that is characterized by the use of thin clients
VDI shares many of the same benefits as server virtualization, such as reduced costs associated with hardware and IT management overhead. Three additional benefits pertaining specifically to virtualized end user computing are:
- Ubiquitous access to user desktops. Users can access their customized desktops from any device that can run an RDP-based application, which establishes the connection, initiates the desktop session, and displays the desktop on the remote device.
- Reduction in security-related concerns over lost or stolen devices. When users have their own personal devices, for example, corporate laptops, desktops, and smartphones, organizations must implement and enforce strict security policies to protect intellectual property and client data. For example, when a laptop is lost or stolen, the organization needs to replace the device for the affected user, and also investigate whether the device might have contained trade secrets or sensitive client data. This scenario can be prevented entirely with a VDI computing model and a security policy that keeps all sensitive information in the VDI and not on the remote device.
- Reduction in security-related concerns over copied files. Organizations acknowledge that desktop users frequently copy work-related files to portable memory devices, clouds, and other personal user repositories. When users can access their virtual desktops from multiple devices, some of these issues are reduced or eliminated, as the sensitive data remains in the VDI, and IT and security policies can restrict users from copying items to external locations.
