When Desktops Go Virtual: Addressing security challenges in your virtual desktop infrastructure

Cover Image

Server virtualization is well on its way to becoming mainstream. Enterprises have achieved significant savings in hardware and operating cost by optimizing resource utilization. This widespread acceptance is due in part to advanced virtualization technologies such as VMware’s VMotion, which have further increased the availability of mission-critical resources. Having experienced the cost and efficiency benefits of virtualization in the datacenter, many enterprises are eager to extend those same advantages into other areas of their business. This has fueled a new wave of virtualization—at the desktop. Enterprises are looking to virtualize desktops to lower costs, speed provisioning, and streamline support and management, often on a much bigger scale than at the datacenter.

Enterprises wishing to virtualize desktops are likely to use Virtual Desktop Infrastructure (VDI), which is similar to a shared application infrastructure, such as Citrix Metaframe or Windows Terminal Server. With VDI each user has access to applications via a thin client, a regular PC, or even a refurbished low performance PC. But instead of running a single operating system on a shared server hardware, every user has his or her own copy of the operating system that can be customized to suite individual needs. Multiple instances of operating systems run on a single physical server, keeping users isolated from each other. This helps to prevent complications from an individual session failure. VDI can also run certain applications natively without being modified.
