If you want to add AJAX to the magic collection of buzzwords supported by your Web site (and who can resist the siren call of the latest buzzword?), then you have two major options: purchase a proprietary package or experiment with open source libraries.
InfoWorld has covered a number of excellent proprietary AJAX toolkits in the past, and now we’re turning our attention to some of their open source rivals. Are they worth exploring for enterprise use?

The open source toolkits I examined span a wide range of what might be covered by the term AJAX, an acronym for Asynchronous JavaScript and XML that began appearing little more than a year ago. The idea of using JavaScript with or without XML to add intelligence and interactivity to a Web page dates from the earliest days of the Web, and AJAX is now one of the best ways to distribute client applications with a minimal amount of fuss. (See more on the intricacies of AJAX.)
If you’re interested in whether these open source packages compete with the best commercial tools, the simple answer is: not in general but sometimes in specific details.
The best-known proprietary packages, such as Backbase, JackBe, and Tibco's General Interface, all offer complete development environments with full toolkits, sophisticated event models, and debuggers. With them, you can write applications that run in the limited environment of a Web browser but offer almost all of the features of native code. (See more on proprietary AJAX tools we've reviewed.) None of the open source packages I looked at come close to the range, depth, and support of these commercial packages.
But that doesn’t mean that there isn’t plenty that’s worthwhile in these open-source AJAX projects — there’s an explosion of interest in the area right now.

Server virtualization is a popular option for dealing with mounting datacenter costs. Another equally promising approach is the use of an Application Delivery Controller. Citrix NetScaler provides a low-cost way for organizations to reduce their server count and accrue cost savings from a reduction in space, cooling, power and personnel.
