Web 2.0 and Service-Oriented Architectures (SOAs) are among the top issues of concern for IT architects and executives. Both are poised for exponential growth over the next few years, due to their flexibility, cost effectiveness, and ease of integration. Each technology creates highly distributed composite applications that unite components or subsystems to form higher-level functional systems or target applications. The growing challenge for enterprise IT architects, however, is that because these composite applications are highly distributed, interactions between components may require several traversals across various areas of the network - each increasing the possibility of inconsistent performance or security problems.
