Java is currently the leading exploit vector for Windows machines, and Java vulnerabilities are packaged into many of the “exploit kits” available in the darker corners of the Internet (see http://krebsonsecurity.com/2010/10/java-a-gift-to-exploit-pack-makers/). Internet Explorer, Flash Player, and even the Windows operating system itself have done a good job of either improving the security of their products or improving their patching processes. Java, however, still lags noticeably behind in both user/media awareness and quality of code. According to some statistics, Java vulnerabilities account for up to 70% of successful exploits, making it a veritable nightmare from a security perspective.
For the last five years, Ruben Spruijt (@rspruijt) and Jeroen van de Kamp (@TheJeroen), two of the leading lights in the desktop and application virtualization market, have been working together on an independent R&D project, Virtual Reality Check (VRC). Together with Login VSI, they have published in-depth studies detailing the performance of application virtualization solutions and best practices for implementing them. Those they have examined use different hypervisors, Windows operating systems, Microsoft Office versions, and antivirus packages in server hosted desktop solutions. In doing so, Spruijt and van de Kamp have created one of the most valuable bodies of knowledge available to anyone looking to implement server-based computing and VDI systems.
It appears that on December 9 of last year, AppSense, a leading user environment management (UEM) vendor, snuck out an expansion to its product portfolio. The expansion is not a new product, but rather new editions of the company’s flagship DesktopNow product, bringing AppSense into line with other vendors that offer multiple product editions with varying feature sets and prices. The DesktopNow suite is a broad set of software that encompasses UEM, application personalization, resource allocation, license control, user rights management, and many other features. For a long time, DesktopNow (and its prior incarnation, AppSense Management Suite) was pretty inflexible. You could buy the three parts of the suite (Environment Manager, Application Manager, and Performance Manager) individually, but that was the extent of the flexibility on offer.
Citrix recently announced that the newly released Receiver for Chrome 1.5 now supports Web Interface 5.4. While that may not seem significant at first, let’s revisit what has changed with Chromebook, as well as with Chromebox, in the interim and take a look at the impact on business adoption. This new combination changes the cost and complexity of virtualization for XenApp 6.5 shops in particular.
In my overview of Desktop as a Service (DaaS) delivery models last month, I touched on availability services, an emerging market that shows strong potential for future growth, and on DaaS services specifically tailored to disaster recovery. Now, fresh from witnessing the slightly embarrassing spectacle of San Francisco grinding to a halt after a little light rain, I thought it would be worth taking a closer look at Horizon Air Desktop DR.
