Radical Desktops Deliver Power To The People. But What About IT?

A slate of contentious issues--social, economic, and technological--will radically alter the business user's computing experience by the end of this decade. Windows XP is the corporate standard desktop and will be for years to come. How employees receive the XP experience, however, will undergo a dramatic shift in as little as two years, whether IT is ready or not. Application and desktop streaming toolsets, robust Web apps, the increasing power

of smartphones, and multiple varieties of desktop virtualization are challenging our basic assumptions about what the terms "computer" and "operating system" mean.Sure, nearly all of today's corporate computing needs can be met with a 5-year-old Windows XP machine running a core of legacy server-based software plus a few Web applications. The dirty little secret of this status quo is that companies are pouring more money into support and upkeep of these fat-OS boxes than they care to admit, even internally, and CIOs have serious doubts about continuing down this path. One proof point: Windows Vista is a bust in the enterprise. In fact, 82% of the 376 business technology professionals who responded to our InformationWeek Analytics Radical Desktop poll say their organizations will still be running Windows XP as 2010 comes to a close; 19% expect to be using pre-XP desktops, such as Windows 2000 or Windows ME.

Part of the reason for XP's almost unnatural longevity: Until recently, CIOs didn't have a good alternative. Now, however, virtualization is transforming the way IT departments view the data center, and myriad players large and small are looking to extend virtualization strategies to deliver "traditional" desktops to employees in a secure, reliable, and significantly less expensive fashion.

So how radical will the shifts be in two years? From an end-user perspective, the look and feel of applications will be similar, though a virtualized desktop means they'll have less administrative power over corporate PCs. Employees will have a much more convincing argument that they should be allowed to choose their devices, as more Web-based applications are ported to run on multiple platforms.

But those responsible for delivering the desktop to employees should get ready for profound change. We're at the cusp of a shift in thinking, and there will be no "right" answer for the desktop of tomorrow. All organizations will host a mix of computing environments--conventional, virtualized, centralized in-house, and hosted off site. Employees will work from a variety of devices, and the only constant will be demand for 24/7 access to personal and corporate resources via ever more browser-based business applications, not just e-mail. In fact, 72% of our respondents work at companies where users access business apps via smartphones.

On the IT side, we expect to see a surprisingly diverse, confusing, feature-rich smorgasbord of delivery mechanisms for desktops and application suites. Seismic shifts are in the works as a wide variety of vendors maneuver to get that XP desktop in front of employees via a variety of methods, old and new.

Topping the list of justifications for moving away from the traditional fat client-server model is total cost of ownership. Analysts and auditors have been bemoaning the ancillary costs of deploying and maintaining desktops since enterprises started rolling them out. Now, the latest round of cost-cutting driven by high energy prices is finally shaking out the details and raising both green awareness and a realization of the bottom-line financial impact of maintaining the support staff to keep depreciated PCs up, running, and even marginally secure.

Roughly one-fifth of our respondents have a fully loaded annual support cost greater than $1,000 per desktop, so it's not surprising that when we asked what would drive them to make a drastic change, the top response was cutting costs. Of course, this is the argument that mainframe pundits put forth during the initial rush to distributed computing, and it's unlikely CIOs will be fooled twice. Before moving to a cloud or virtualized model, all the companies we spoke with will do exhaustive TCO analysis, so vendors should get their spreadsheets in order.

Of course, most of the savings comes from reduced staffing costs, never something IT wants to hear.

Desktop virtualization promises easier management for IT and an optimal experience for users

Spurred by the business benefits gained from server virtualization, enterprises now are embracing desktop virtualization for many of the same reasons: flexibility, lower costs and ease of management.

The latter has been huge for the University of Maryland in College Park, says Jim Maloney, network applications manager at the school, which has been using desktop virtualization since November 2007. The university hosts 50 -- soon to be 250 -- virtual PC images on two VMware ESX servers running the Sun Ray Server Software and Sun's virtual desktop software. Users access the images from Sun Ray terminals. "Overall, we've saved 30 hours a week in management time -- practically one full-time employee," he says.

Others look to desktop virtualization as a hedge against the cost of future PC upgrades. "Compared with traditional desktops, virtualization is a no-brainer," says Kunal Patel, IT manager at Nina Plastics, a packaging manufacturer in Orlando. Nina hosts 50 virtual PC images on two ESX servers using Pano Logic's Virtual Desktop Solution software. Users access the hosted images from a specialized hardware-only device into which they plug their mice, keyboards, displays and network connections.

"We were spending between $700 and $1,000 per desktop, whereas the Pano device costs just $300. And an actual PC eventually becomes obsolete and has to be replaced. With the Pano, if we want to upgrade the entire company's desktops, we just upgrade the few servers we have and we allot more memory or faster speeds to the images. It's a concrete dollar savings," Patel says.

Plus, users get unprecedented flexibility: They can

access their desktops from virtually any device residing anywhere, as long as they have good network connections. Instead of sharing centrally hosted applications, they access their full desktop images complete with familiar applications and customized wallpaper -- the final fulfillment of the thin-client ideal.

One, two, three approaches

Desktop virtualization requires a hypervisor, such as VMware ESX, Citrix Systems XenServer or Microsoft Hyper-V, running on a data-center server to host the desktop images. Vendors differentiate themselves by the overlying desktop virtualization-management software that brokers the connection between the virtual PC image and the actual client, be that a Macintosh, Linux or Windows PC; thin client; RDP
