XenApp 6.5 is Citrix’s latest offering of their renowned Presentation Virtualisation (PV) service. Citrix are not alone in updating their feature set. Earlier in 2011 Microsoft introduced SP1 for 2008 enhancing the OS for the core Remote Desktop Services’ (RDS) session virtualization service, Ericom released PowerTerm WebConnect 5.7.1, ProPalms updated TSE to 6.5 and Quest announced vWorkspace 7.2 MR1.
One of the reduced criticisms of View, and one of the most frequent weapons used against it, has been the relatively poor performance characteristics of PCoIP across high latency low bandwidth WAN connections. Until today, VMware has been following the standard line of denying there is a problem until you are able to solve it. Now, solution in hand Vittorio Viarengo, VMware’s head of all things desktop (officially Vice President, End User Computing)is willing to share Gartner’s perspective on View’s strengths and weaknesses.
The Virtualization Security Podcast on 10/21 was the third in a series of Virtual Desktop Security discussions we are having. The special guest panelist was Chris Mayers of one of the Chief Security Architects for Citrix, the makers of XenServer, XenClient, and the FlexCast solutions. FlexCast provides an all encompassing method to provide virtual desktop and applications that include the following mechanisms:
Let us look at each of these mechanisms in a bit of detail then discuss how they work to provide Security and how to secure them.
If you’re from a Presentation Virtualization (PV) background (although maybe you know it as Terminal Services (TS); possibly even a Microsoft Remote Desktop Services (RDS); heck lets go on an old school ‘server based computing’ perspective) what vendors should you be looking out for at VMworld?
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.
Indeed a challenge in migrating to a Hosted Virtual Desktop (HVD) solution is what to do with existing devices. Citrix’s High Definition User EXperience (HDX) technologies for example, typically relies on the end device supporting a Microsoft Windows operating system to deliver the best user experience. If that is the case, how will you manage the end device that delivers the user’s HVD? Vendors such as DevonIT, Igel, and 10ZiG would naturally suggest you replace your traditional PC with a Thin Client: vendors such as PanoLogic, Teradici and Wyse would highlight the advantages of Zero Client devices – yet moving away from existing devices is a costly exercise in terms of providing replacement devices. And indeed – still does not address off-line working.
