Scaling Web Applications with Windows 2000 Advanced Server's Network Load Balancing
With ever-larger Web applications being built to service very large numbers of simultaneous users pounding away at Web sites, the issue of scaling applications beyond a single machine is important for Web application developers and network administrators.While hardware capabilities seem to be increasing to the point that high-powered single machines can handle tremendous loads, there will always be those apps that push beyond a single machine. In addition, for many administrators and IT planners, it's often not good enough to say that a server can handle x number of users. They want redundancy, backup and overflow support, so a Web server or hardware failure or an unexpected surge of visitors doesn't cripple the corporate Web site.

XML is quickly becoming the preferred method of passing information, not only for the Internet, but also across applications and within applications.Until now, developers have been forced to create our own routines to convert data stored in a database system into XML.
