In many a desktop virtualization project, there will be a discussion around the type of desktop virtualisation to use. Before you even get to the entertaining “Citrix vs VMware vs Other” quasi-religious debate, there will be a VDI vs RDSH altercation. It can altercate for days. Ultimately, no business question gets asked, nor decision made, as technical stags lock antlers. It is not unusual for this debacle to be silenced by someone simply getting tired of the PoC posturing and rolling out pallet loads of new PCs.
If any year is to be the year of virtual desktops, then it is not just simply a question of having nifty appliances, but also of having a better understanding of desktop virtualization solutions. A recent article from the BBC website on common language gave the ultimate benefit of a common understanding as “world peace”. If a better understanding between people can bring the laudable hope of goodwill unto man, then surely an easier corporate upgrade and better application access will be a mere bagatelle?
The options for purchase for VDI or RDSH, VDI or Terminal Services, for hosted desktops or session desktops are all the same conversation. RDSH is indeed on the back foot through regular re-marketing of terms. Presentation Virtualization Terminal Services and RDSH are the same thing: a multi-user server OS capable of hosting applications and desktops to remote users.
Increasingly, desktop virtualization vendors are ensuring they sit between both VDI and RDSH camps. Citrix obviously – XenApp and XenDesktop. In our Presentation Virtualization whitepaper, every RDSH vendor has a VDI option. But also, “traditional” VDI vendors are being more savvy. Desktone offers a RDSH option. Teradici has delivered on their promise and recently announced Teradici Arch, a software solution for RDSH.
What are the similarities and differences between VDI and RDSH? What can calm everything down and make the combatants think about what it is that they have done?

Project Virtual Reality Check (ProjectVRC) have finally released their ‘Phase V’ white paper which provides an independent insight into the impact and best practices of various antivirus (AV) solutions on VDI performance. Continue reading News: ProjectVRC Releases New White Paper about Impact of Antivirus on VDI
2010, 2011, 2012, were all labeled “The Year of VDI”. 2010 and 2011 failed to live up to the hype, what about 2012 , was 2012 “The Year of VDI”?
Without question the answer must be “yes”. Continue reading Was 2012 “The Year of VDI”?
Participate in any virtual desktop design session and you will know that the discussion almost always moves immediately to how many IOPS per virtual desktop session should be expected. More often than not, the leader of these conversations will answer “it depends”. This is a statement that does not give most end users a warm a fuzzy feeling because it usually comes with a pretty heavy storage price tag. Unfortunately, there are many factors that affect overall performance. Within the virtual desktop session, the number and type of applications you have running, the layers of security configuration and policy that are applied, and how you are handling user personalization have an impact on IOPS. Many of these challenges can be addressed by applying good standard virtual desktop practices, which are often different from the way physical desktops are traditionally architected.

Recently I have been trying to lighten my conference going load. To do that, I have been thinking about ways to do without my laptop and all the accessories for it, which got me thinking about what it takes to completely use such a device; to fully embrace the next generation of end-user computing using gesture computing and smaller devices. Other than the technical hurdles, there are also training hurdles as full tablet computing, today, has some serious limitations with respect to security, functionality, and in some ways capability. So how does one embrace tablet computing as their next-gen end user computing?

I originally arranged to interview V3 systems CEO Peter Bookman at VMworld in San Francisco back in October. However, we weren’t able to schedule the time until the final day, by which point we were both so tired that we never got past the “talking about cars” stage. I finally caught up with Peter last week, and this time we managed to get past the “talking about cars” stage. I tried to limit myself to just asking questions rather than sharing my opinion, and I’ve made a couple of edits for clarity and tidied up product names etc. where appropriate, so any errors in the transcript are mine.
