John Michelsen's Blog It will take a while for SaaS in a Cloud Computing model to catch up with SOA. One obstacle for the pure plays in the cloud to join SOA is to recognize and deal with the increased testing and validation of data from even more diverse sources, as well as the governance and validation of all the underlying technologies that contribute to specific business outcomes. I'm on my way to STARwest in Disneyland, CA today, and since it's been a little while since my last software quality-focused conference, I'm particularly interested to see how these testing experts and vendors are addressing the needs of a more distributed computing environment. Our own expert Rajeev Gupta is coming in to present "Building the SOA Quality Center of Excellence" at 11:30 PT on Thursday Oct. 2. Joe McKendrick recently posted, CTO Predicts SOA Will Fade into SaaS. He quote... (more)

SOA World Expo: The Agile Life Cycle for SOA

John Michelsen's iTKO Blog In the past, test “scripts” in TM tools were largely recorded as actual step-by-step instructions (in a Word doc or Excel spreadsheet) for a manual tester to point-and-click through a finished interface to test the application. When tests were completed, the tester would then “check a box” in the test management UI, to indicate that the test had passed or failed. With so many changing components and middle tier systems in today’s enterprise apps, that form of manual testing is no longer enough, so teams are trying to define (and run) far more sophist...

How to Manage Application Performance and Load Testing in Virtual Environments

Gone are the days when you could test an interface to a single client/server app and know that you have performance covered. Today's interconnected systems such as fully integrated packaged applications, ESB-based enterprise platforms, and SOA make ensuring high-performance from application components and solutions increasingly difficult. On top of that complexity, we are increasingly supporting technologies that are built and managed by distributed teams, both across organizational and geographic boundaries. High-performance applications are critical to today's business. Clearly ... (more)

Agile SOA Across the Lifecycle with LISA

John Michelsen's iTKO Blog In this series we are going to look at four aspects of the Agile lifecycle: test & quality management, application lifecycle management, IT operations, monitoring and performance, IT and SOA governance. For years, testing was an siloed activity that used different and unconnected tools within specific phases of the application lifecycle. First, a development team would run a suite of JUnit tests as part of a build process. Then a QA team would manually create and run a suite of functional tests against a user interface. Performance teams would use a separ... (more)

Is SOA Dead, Doomed, or Misnamed?

Many in the media are already calling on the demise of SOA and saying that it's just a passing phase, or it's really just a rebrand of the EAI space, or that it will be segmented only to certain integration-type challenges. We have a bit of a different take. The term SOA will go away over the next several years but it will go the same route that e-commerce applications went. If you think back to the mid-'90s, we started talking about e-commerce as an architecture that was distinct from the then traditional enterprise architecture. However, over the past few years, e-commerce as a... (more)
