And companies that are provisioning hundreds of presentation desktops on a single XenApp server will have to add hardware to serve up that many versions of Windows using XenDesktop. Roussain says a Citrix server that could provide 200 to 300 presentation desktops can handle maybe 30 virtual machine desktops with XenDesktop.
The brewing fight between VMware and Citrix in the desktop virtualization market will ultimately be a good thing for customers, said Brian Madden, an independent industry analyst who publishes a popular desktop virtualization blog. "For the past 10 years, Citrix was an absolute monopoly. There was no one else at the enterprise level doing what Citrix was doing," he said. We're going to go, for the first time, to market-driven pricing versus monopoly-driven pricing."
In fact, some customers may already see signs of this in Tuesday's announcement. Enterprise and Platinum XenDesktop customers get a free license to use XenApp with their virtual desktops. Normally, XenApp costs $450 per concurrent Enterprise user and $600 per Platinum license. That's more than the $295 and $396 that Enterprise and Platinum XenDesktop users pay.
Available immediately, XenDesktop also comes in Standard and Advanced editions, which cost $75 and $195 per concurrent user.
