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.

VMware has said that is it committed to its Desktop Virtualization Strategy but VMWare’s commitment to VDI as the only solution is going to mean that unless you are only going to deploy VDI you’ll likely consider another vendor to help you achieve your goal.
There are two desires which are fundamentally in conflict, and addressing this conflict is the biggest opportunity in desktop computing. Can you manage the demand for users to have effective IT at their fingertips while controlling access and costs from the centre?

The Virtualization Practice’s Presentation Virtualization Comparison Whitepaper discusses PV in relation to business’ application and desktop delivery needs. This updated release adds Aqua Connect’s Terminal Services for Mac Series 3 to those products from Citrix Xenapp, Ericom’s PowerTerm WebConnect RemoteView, Geniut’s ThinWorx, GraphOn’s Go-Global, Microsoft’s Remote Desktop Services, Propalms’ TSE, Quest’s vWorkspace, Systancia’s AppliDis Fusion and 2x ApplicationServer.

Which is better – Virtual Desktop Infrastructure or Presentation Virtualization? If you have, say, a Citrix XenApp PV solution – you may may be tempted at the reduced cost per license of VDI – XenDesktop appears to be almost half the cost per user than XenApp. Maybe you’ve a VMware vSphere back-end and the thought of having one platform to manage is appealing. Maybe you have a different solution – perhaps Quest’s vWorkspace or Ericom’s Webconnect and are wondering what all this fuss about moving between PV and VDI is all about?

If your organisation has remote users – consider that the impact of centralisation on their desktop experience can be very different: and not always in a happy way. Citrix’s ICA protocol has been joined by the likes of Quest’s vWorkspace with EOP Xtream, or Ericom Blaze. There are a number of hardware solutions for WAN optimisation with the likes of Expand Networks focusing specifically on solutions to support VDI implementations. Don’t allow poor network performance and user experience to sabotage your desktop virtualization project.

Citrix have invested an unspecified amount of money in Kaviza whose grid architecture eliminates the expensive infrastructure that VDI solutions. With Kaviza’s solution all the functionality needed to provision and manage virtual desktops is consolidated into a single virtual appliance that scales on commodity servers. Will this announcement herald a major take-up of VDI? Indeed, can you really offer a turnkey solution to support your desktop centralisation strategy?

Citrix has released XenApp 6 which finally provides support for Microsoft Windows Server 2008 R2 – what is available in this new release for your business. Besides R2 support, what does XenApp 6 offer your business, what WOW factors are provided to help justify the cost of using XenApp6 to springboard your x64 Presentation Virtualization implementation – be that a new implementation, or a migration from your existing environment.
