Rich Internet Apps Move Beyond The Browser

Forrester clients are adopting rich Internet applications (RIAs) because they demonstrate clear benefits. Early RIAs were exclusively browser-based, but new platforms from Adobe, Microsoft, and Sun Microsystems broaden developer options for delivering rich media and content to clients. Adobe Integrated Runtime (AIR) extends Web development to the desktop, while Microsoft Silverlight takes the .NET Framework and Windows Presentation Foundation cross-platform and cross-browser. Sun Java FX extends Java's reach with a new mobile offering and improved scripting for the Java virtual machine. Microsoft has a tactical edge because its dominant position at the desktop with the .NET Framework will attract large numbers of developers who already target Microsoft's desktop and browser platforms. However, if Microsoft is to succeed strategically and displace Adobe's offerings, it will have to ratchet up its appeal to designers and content providers to match its standing with developers. While Java developers will find Java FX appealing, Sun will need to improve its RIA developer and designer tools to be competitive in the long run.
