The Virtualization Practice

Presentation Virtualization

Presentation Virtualization is an application delivery method that delivers users desktops and applications from a shared server, AKA server based computing. This method of delivering applications to users focuses upon running an instance of each Windows desktop operating system application i.e., Word, Excel, PowerPoint and Office for each user on a shared instance of a Windows Server operating system. ...
The most popular product in this category is Citrix XenApp and its predecessors which include Citrix Presentation Server, and Citrix MetaFrame. In the 6.0 releases of its products, Citrix bundled XenApp into XenDesktop. In the 7.0 releases of its products, XenApp has been made available separately again. Microsoft also has a product in this category – Microsoft Remote Desktop Services, but this offering is mostly used in smaller implementations that do not require the enterprise class features that Citrix offers.

How good an idea to Virtualize XenApp? There were a number of benefits identified way back then: hardware abstraction allowing easier image management and OS upgrades; options for higher availability and faster recovery; even fail-over. Virtualization enabled silo consolidation and importantly enabled better management of user capacity on servers. However, there is a price. Reduced density and performance. Not all applications will benefit. That said, the flexibility that virtualization of XenApp offers is likely of greater benefit to many organisations.
