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.

Performance Management for Desktop Virtualization (VDI) and Presentation Virtualization (SBC)

Ovum’s research found that desktop virtualization currently represents approximately 15% of the business PC market. However, this figure is dominated by the Presentation Virtualization model (12%), typically used in call datacenter-type environments, and has been for the last 10 years. If PV/terminal services are excluded, the next generation of solutions aimed at CIOs, from the likes of Citrix, Quest and VMware, hold less then 3% of the market, showing that many CIOs are holding back from taking the plunge.

At Citrix Synergy 2011 in San Francisco last month Simon Crosby made the case that the biggest barrier to the adoption of service-provider offered cloud services is the understandable lack of trust on the part of enterprise customers. Well it looks as if he and fellow Xen luminary Ian Pratt have decided to do something about that lack of trust and are moving on from Citrix to address the problem at its source. Ian and Simon announced today that they are both leaving Citrix and taking key roles along with with Gaurav Banga (the creator of Phoenix Hyperspace) as co-founders of cloud security start-up Bromium.

The changes dubbed “License Mobility” announced at the Microsoft Hosting Summit in March this year,will move will allow customers with Software Assurance to move their applications to a cloud services provider without paying a premium for the added flexibility this will bring.

VirtuAll User Environment Manager Released

About 18 months ago fellow Citrix Technology Professional Pierre Marmignon realized that there was a gap in the market for a simple robust user environment management solution that could remove the continual nightmare of managing complex Windows logon scripts and user environment settings in virtual desktop environments. Skip forward to today and Pierre has just announced the release of VirtuAll User Environment Manager (VUEM), and it is excellent.

RES Software confirmed today that it is has signed an agreement with Citrix to license RES’ reverse seamless Windows technology.

Citrix confirmed that while it has a license to use RES Virtual Desktop Extender (VDX) it does not intend to integrate RES’ VDX solution into it’s own products. Instead it has taken out the license to allow it to implement its own reverse seamless solution without running afoul of the patent that RES holds on reverse seamless Windows.
