Apollo helps Adobe compete with Ajax
Published: 23 Mar 2007 09:55 GMT
Adobe Systems' Apollo software is at the vanguard of an emerging set of technologies that seek to improve on Ajax, perhaps the most popular style for writing interactive web applications.
Adobe on Monday released an alpha, or early, version of Apollo, software that can run web applications both online and offline.
Reaction to the release has been enthusiastic among programmers who create so-called rich internet applications (RIA), cross-operating system applications that combine the interactivity of desktop software with the web.
Ajax-style development, used for many Web 2.0 services, improves on the interactivity of web applications, compared with those of only a few years ago. Web 2.0 generally refers to web services that let people collaborate and share information online.
But Adobe's Apollo and other alternatives offer some advantages over Ajax, said Richard Monson-Haefel, an analyst at the Burton Group. For example, Flash-based applications can run multimedia content such as video, and Java has a richer set of development tools. Now the ability to mix online and offline content is coming to the fore.
"In terms of trying to capture the development community, I'd say [Apollo] helps Adobe compete more with Ajax," Monson-Haefel said. "Offline development is becoming a real issue now. You need to make applications available offline, and Ajax can't do that."
In addition to Apollo, slated for a version 1.0 release in the second half of the year, there is a growing roster of rich internet application platforms, including Adobe Flash-based tools, Java, and Microsoft's Windows Presentation Foundation/Everywhere (WPF/E), which is still not generally available.
Which of them will become the most popular among programmers remains to be seen. But many people believe that the richness of the latest generation of tools will usher in more full-featured web applications as well as hybrid applications that cross the line between the web and desktop.
"The fundamental thing is that Apollo is enabling innovation on the web to come onto the desktop. These have been completely separate worlds," said Kevin Lynch, chief software architect and senior vice president of Adobe's platform business unit. "Potentially, we're going to unveil a flood of innovation on the desktop."
Pushing the limits of the web
Virtual Ubiquity, a 10-person start-up staffed with IT industry veterans, decided to forgo Ajax when it set off to make an online word processor about a year and a half ago.
The company tried to write a prototype using a range of development technologies but eventually decided to use Adobe's software, said company chief executive Rick Treitman.
The word processor, called Buzzword, runs in Adobe's Flash and is built using Flex 2.0, Adobe's development software for writing rich internet applications.
"We're convinced this is the only way we could write this product," Treitman said, adding that his team looked at Java and JavaScript, which is commonly used for Ajax programming. "The other technologies just didn't take us where we were going."
Virtual Ubiquity intends to build a version of its application for Apollo as well, he added. Company engineers will build an offline option for its Flash-based word processor. But using Apollo will make the offline capabilities more "elegant", Treitman said.
An important factor in choosing Flash is that it is installed so widely in browsers, he said.
Indeed, having a single vendor control a browser plug-in, such as Flash or WPF/E, means that developers have a more consistent platform for running applications compared to Ajax, Monson-Haefel noted.
Many developers prefer open standards-based web development, such as using JavaScript, rather than…
