Terminal services take on VDI
This article is part of the Virtual Data Center issue of March 2009, Vol. 8
Historically, data center managers have struggled with desktops and other endpoint devices such as PDAs because of the ongoing security and support needed for each device. Desktop virtualization technologies such as virtual desktop infrastructure (VDI) and application virtualization through terminal services products promise to mitigate these challenges by centralizing critical parts of the endpoint within a data center itself. But which option should data centers choose? By taking advantage of today’s desktop virtualization technology, organizations can opt for VDI with platforms such as Citrix Systems Inc’s XenDesktop or VMware Inc’s View. The VDI approach runs complete instances of each user’s desktop on a server, which handles all processing and delivers only the I/O activity of that instance to “dumb” endpoints. Still other organizations can choose to centralize applications only and provide access to end users through features such as Remote Desktop Services in Microsoft’s Windows Server 2008 R2 or Citrix XenApp, formerly ...

Features in this issue
High-availability solutions ensure uptime and help avoid infrastructure problems. But without virtualization, their hardware and software requirements can be quite pricey.
Evaluate failover capabilities, service-level requirements and shared storage before choosing high-availability software to create a high-availability architecture.
Terminal services offerings reduce memory and storage requirements and allow far more users to share an application at the same time.
