Why migrate to XenApp 5.0 on Windows Server 2008?  That’s the burning question.  As with any major platform change decision, many IT decision makers will be wondering whether or not they should upgrade their existing XenApp servers to 5.0 running on 2008.  While a migration project seems a daunting task, there are good reasons to go down that route – money being one important factor, especially in these economically challenging times.

CFOs will undoubtedly ask the inevitable questions with regard to how much money a migration project will save and how long it will take for the savings to materialize.  Well, the Citrix Consulting Solutions team has just wrapped up some performance testing that makes it easy to answer these questions.  Single server scalability testing was conducted in the Fort Lauderdale Solution Center lab to see how many users could work happily using Microsoft PowerPoint and Word 2007 delivered via XenApp 5.0 on W2K8 Server (32-bit and 64-bit).  Our testing revealed that XenApp 5.0 (32-bit) on W2K8 Server was able to handle 12.5% more users than Presentation Server 4.5 (32-bit) on W2K3, and the 64-bit version of XenApp 5 on W2K8 64-bit allowed 50% more users.  For more details on the testing, you can check out the XenApp 5 Scalability Analysis.  Our test results also proved that moving from Presentation Server 4.5 (32-bit) to XenApp 5 (32-bit) results in a 6% decrease in TCO and moving from Presentation Server 4.5 (32-bit) to XenApp 5 (64-bit) results in a 32% decrease in TCO.  For more information, please refer to the Reduce IT Costs Using Citrix XenApp 5 whitepaper.
