Virtual Desktops (Thin Clients, VDI)

Overview

With virtual desktop infrastructure (VDI), users connect to their desktop environment remotely with a "thin client." This eliminates the need for powerful processors, large hard drives for storage, and constant system updates. With VDI, all software, security programs, and hardware are operated on a remote server where an IT professional maintains the entire system, including updates.

Features

  • Lower total cost of ownership. Thin/zero client workstations have the advantages of longer equipment lifecycles, lower initial cost, and less power use than a traditional desktop.
  • Efficient use of resources. Each thin/zero client server is capable of running up to 200 sessions simultaneously.
  • Increased security. Data remains in the ISU data center rather than being stored on hardware that could be lost or stolen.
  • Decreased recovery time. The recovery time after an infection or upgrade to a new operating system decreases from hours to minutes.
  • Ease of updating. Lab managers can update entire labs remotely in minutes, or present multiple configurations in the same lab based on who logs in to the endpoint.
