By the first half of 2009, Citrix will make its XenDesktop and XenApp client and server software for remote access to Windows applications available for the iPhone. “We expect to have it sooner rather than later,” said Chris Fleck, vice president of Solutions Development at Citrix .
The company is addressing an “unbelievable market demand” for such a product. Requests have become the number-one topic of discussion on its blog site. Citrix XenApp virtualizes an individual application, be it Microsoft Office, PowerPoint, Excel, or SAP, allowing users to run those applications on a client directly from a XenApp server hosted with a Windows application like SAP. XenDesktop provides access to a centrally hosted desktop, in particular a user’s desktop on a remote server.
Similar Citrix technology is available for Windows Mobile devices and devices running the Symbian operating system. However, in the case of the iPhone, Citrix has tweaked the XenApp and XenDesktop technology so that it can leverage the unique features and capabilities of iPhone, such as touch gestures, pinch and pull, zoom, and pan. It will make available the entire world of a half-million Windows applications. Citrix developers worked with Apple to design the iPhone version of the Xen App and Desktop in order to preserve as much of iPhone’s unique capabilities as possible. For example, although an enterprise application remains unchanged, users accessing that application on the iPhone will be able to use iPhone’s Accelerometer technology to change screen view from portrait to landscape to help provide visibility, usability, and navigability.
