In today’s high-tech world there is a growing need to create a simpler way to describe web-based applications. In the past one would use a WSDL to describe such application. One competing project put forth from Sun is Web Application Description Language [WADL] (http://research.sun.com/techrep/2006/abstract-153.html).

One of the first notations made in my notes from the ZapThink session (see Zapthink LZA Reviewed) was a subtle disagreement about the relationship between Architecture and Technology. ZapThink asserts that “Architecture is not about technology.” They paraphrase “physical”* architects stating that buildings are and should be designed “for the space.”
While this is not untrue, a review of classic architectural writings reveals a fuller and more enlightened perspective. In point of fact, Architecture is about the spaces and the structure and the foundation. Physical Architecture does in fact concern itself in no small manner with the structure and foundation of the building. Without a solid and proper foundation, even the best and most suitable “spaces-based” Architecture will fail. The spaces based viewpoint might come from the fact that in the world of physical Architecture, structures and foundations are usually a known quantity, as a great deal of experience has been recorded over the past few thousand years. However, whenever a new material or technology is introduced, inherent unknowns often produce failure. With this failure and its study comes further understanding.

In today’s application development environment it is standard practice to build unit tests for each object being developed. Unit testing is increasingly more and more popular in Java due to the many open-source unit testing frameworks available. However, this type of testing becomes more difficult when the application is Web based or contains EJBs because of the dependency on application servers, servlet containers and EJB containers. We can, though, test the publicly exposed portion of the Web application with frameworks like HttpUnit.

ZapThink launched LZA (Licensed ZapThink Architect) Boot Camps in early 2007 to provide a SOA credential and matched training. The Boot Camps were intended to provide both a common, objective understanding of SOA to practicing Enterprise Architects and the chance to obtain a credential from a qualified and respected third party (ZapThink).

Many SOA advocates refer to the implementation of SOA as “wrap and replace” rather than “Rip and Replace.” createTank has determined through experience that a more refined description might sometimes be helpful — that of “wrap and replace ‘the squeaky wheel.’” This description is usually more acceptable to developers and management alike, as it highlights the possibility that a great deal of legacy code may not need to be rewritten at all (or at least not immediately).

Sometimes I suspect Bill Gates doesn’t sleep so well at night. Not out of any guilt over his billions or the alleged mediocrity of his product. No, I wonder whether he might actually worry about the competition. Not Apple (though that iPod MP3 player is a killer toy, and I’m cheerfully typing these words on an Apple (AAPL) PowerBook G4). No, I’ll bet Linux and its creator, Linus Torvalds, cross Gates’s mind when he’s looking up at the ceiling late at night.
