So, does testing change with SOA? You bet it does. Unless you're willing to act now, you may find yourself behind the curve as SOA becomes systemic to all that is enterprise architecture, and we add more complexity to get to an agile and reusable state. If you're willing to take the risk, the return on your SOA investment will come back three fold...that is, if it is a well-tested SOA. Untested SOA could cost you millions. Truth be told, testing SOAs is a complex, disturbed computing problem. You have to learn how to isolate, check, and integrate, assuring that things work at the service, persistence, and process layers. The foundation of SOA testing is to select the right tool for the job, having a well-thought-out plan, and spare no expense in testing cycles or else risk that your SOA will lay an egg, and have no creditability. Organizations are beginning to roll... (more)

Where Have All the SOA Standards Gone?

To mark a new standard in the SOA space, I create a Google Alert and sift through the pile of links returned to get the scope of its maturation. I'm currently tracking over 60 standards, starting with SOAP and XML (XML happened way before Google was cool). Lately I've noticed a drop in the number of blogs, links, and articles talking about particular SOA standards. Where I once got dozens of links a week on some standards, I now get only one or two or none. So, I'm thinking that standards, although around, aren't as cool as they once were, and maybe people are a bit confused by ... (more)

SOA World Expo: Virtualization-in-a-Box?

Earlier this month I attended the IBM Impact conference in Las Vegas.  The core theme of Impact was "Smart SOA" and how cloud computing comes together in the enterprise, with the emphasis on private clouds.  The core notion of private clouds for IBM is really about extending their experience in virtualization, which is vast, into the more modern world of cloud computing.  They hope to sell some hardware and software in the process.  IBM considers private clouds strategic to its platforms.  The movement to private clouds plays right into its hands.  Recently they are announced a ...

Building a SOA...

While the notion of SOA continues to emerge, those who are implementing SOAs today are faced with a variety of challenges, including the complexities of SOA, and the work involved with understanding their existing problem domain and requirements. Those who want to get SOA right the first time quickly understand the benefits of a sound architecture and a good set of SOA design approaches. However, the understanding of how you approach your SOA, and best practices around building a SOA, are clearly lacking. Those who are looking to gain the benefits of SOA are perplexed by the wid...

Should SOA and Good Architectural Governance Become a Corporate Responsibility?

While few will disagree that the inefficiencies of existing enterprise architectures have reached a critical level, many count on "flying under the radar" of those who look at a company's efficiencies. Let's face it; enterprise architecture is very technical and difficult to understand by the layman. The well-publicized corporate scandals have focused on shady accounting practices and corporate mismanagement while IT has gotten a pass in years past. This will no longer be the case. Today, those who look at value and invest in a company poke around all aspects of a corporation, ... (more)
