For years, the Citrix Systems cheerleading team waved its pom-poms to the resounding chant of “Any, Any, Any!” Any app, anywhere, on any device, knowing all too well that while it could deliver apps anywhere and on any device, its ability to do so for anything other than Windows apps was nothing more than some well-crafted marketing hype.

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.
Over the past few weeks, I have been putting several DaaS providers under the microscope. I first looked at Amazon WorkSpaces and found it to be a decidedly lackluster service that was all the more disappointing coming from a company that has a proven ability to do far better. Next I looked at dinCloud, an independent DaaS platform developer and hosting provider, and found a capable second-generation DaaS platform being offered with a better SLA, lower cost, and greater flexibility than Amazon provides, from a company that knows and understands desktops. Having said that, dinCloud’s big differentiator over Amazon is not the incremental improvements it offers over Amazon WorkSpaces, but rather is something that Amazon is actually very good at: enabling customers to add value through service automation—in short, providing a DaaS API.
Atlantis Computing have released the first in-memory storage solution for persistent VDI. Setting aside the remoted experience, peripheral support, licensing and off-line access – the most nemesising nemesis for VDI is hardware scale. A major hardware limiting factor is storage performance.
In a transition from physical PCs to virtual work spaces you can move 50,1000,20,000 people from an environment where everyone has their own hard drive in their own device, to a shared environment where there are (hopefully) no longer 50,1000,20,000 hard-drives. You do this to achieve cost savings. Still, in the majority of instances, the desktop file system and the apps that run on it weren’t designed to understand such consolidation. Many a desktop project fails because the storage infrastructure wasn’t architected with these mismatches in mind.
Yet, desktop virtualization solutions have have matured to accommodate such issues. A range of increasingly impressive VDI appliances: dedicated drive arrays. Way back in 2010 we were reporting that Atlantis Computing were looking to Transform Desktop Computing with their In Line Image and Optimization (ILIO) product. Atlantis Computing’s core ILIO product sought to address optimizing non-persistent VDI instances, then offered a RAM based solution with their ILIO DiskLess VDI, then presented a way to optimize Citrix XenApp instances. Atlantis’ offerings look to dramatically reduce the physical hardware required to support virtualized desktop infrastructures.
And now to their portfolio, Atlantis Computing add ILIO Persistent VDI 4.0. Some early stability issues aside, Atlantis have developed a strong and supportive market and expanded on it. What is in this release? If 2013 is to be the year of VDI – how does ILIO Persistent VDI 4.0 help? Importantly, will Atlantis Computing’s ILIO Persistent VDI change the game?
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?
