Citrix, Apple Working on iPhone Integration
Integration with XenApp and XenDesktop expected to be available early next year.
VMware's recent purchase of Trango Virtual Processors brought
attention toward a previously little-known market segment: virtualization
. To date, most of the telecom activity has centered on virtualizing
mobile phones. While estimates vary concerning the degree of market opportunity
in telecom virtualization, many analysts agree that the potential is significant.
So far, there's been little competitive activity in response to VMware's acquisition.
Some VMware competitors are involved in the mobile handset market, although
not quite in the same way. And while Microsoft provides specialized OSes such
as Windows Mobile and is a leader in datacenter virtualization, it has yet to
make any major announcements about its mobile virtualization plans.
On the other hand, Citrix, VMware's other major competitor, is currently spearheading
some significant efforts with respect to Apple's iPhone. Though Citrix hasn't
made any formal announcements about this partnership, sources at the company
say it is working to develop virtualization software that will securely migrate
a Windows desktop to an iPhone.
The iPhone's potential for business use has been a much-discussed topic. "We
view the latest- and future-generation mobile handsets as a logical extension
of corporate IT infrastructures. Due to obvious size and convenience factors,
employees will increasingly use mobile devices rather than laptops during travel
and customer calls," said Charlie Burns, an analyst with Saugatuck Technology.
But many businesses have not switched to the iPhone because of its lack of
full integration with corporate e-mail systems. To address this problem, Apple is moving toward a more BlackBerry-like iPhone, announcing in
March that it was working to revamp its software to support Microsoft Exchange
-- a shot to the bow of Research In Motion, the company that makes
But e-mail is just the first step. "While mobile e-mail and instant messaging
are early examples of this use, more sophisticated devices enable viewing, modifying
and displaying files such as Word, Excel, PowerPoint. And, for reasons such
as employee productivity, companies will move to deliver business applications
via mobile devices." Burns said.
The Citrix solution would accomplish much of the same sort of integration that's
taking place with Apple and its business software partners such as SAP, but
in a more organized and comprehensive way. It would integrate both XenApp (formerly
known as Presentation Server) and XenDesktop products; XenApp would allow specific
applications to be pulled off a subscriber's desktop, while XenDesktop would
allow the entire desktop to be accessed.
Having XenApp on an iPhone would offer the advantage of security, a major concern
whenever business apps are migrated to mobile devices. According to Chris Fleck,
vice president of solutions development for Citrix, this is one of the biggest
reasons more companies haven't moved to iPhone implementations.
"The big issue that customers we talk to are concerned about is the same
thing they worry about with laptops...that they will be lost or stolen with
critical information on the device," Fleck said. "In a Citrix environment,
the data never resides on the device -- it's always on a secure server back
in the datacenter."
According to Fleck, XenApp is scheduled for implementation first in the timeline.
He added that Citrix expects the products to become available in the first half
of next year, when the Citrix software will be downloadable from Apple's App
Citrix wants to bring its presentation and hosted desktop virtualization product
offerings to as many different types of devices as possible. The company has
mobile clients available today for both Windows Mobile and Symbian devices,
but there are performance drawbacks. However, the increasing availability of
3G combined with the iPhone opens new windows of opportunity: Both screen size
and zooming features make applications easier to use, and improved response
time is now possible via the bandwidth capacity of 3G wireless coverage, now
accessible with the latest version of iPhone.
