Imagine for a moment that you’re a software developer who has been charged with adding a new feature into your company’s billing system application that allows bills to be automatically sent to customers via email. You spend weeks, possibly months, working on the new function, and then at some point you move to the unit testing phase. You set up an environment, configure the product with the new feature, and then you run tests to verify that emails with valid billing information are indeed being sent as expected. Once you’re satisfied with the unit testing, it’s time to hand it over to the testing team so they can put it through the paces. At this point you have come to the time dreaded by just about all teams involved in the application development lifecycle: The Hand-Off. If any of you reading this have spent time in software development, you’ve undoubtedly dealt wi... (more)

Setting Apart WebSphere CloudBurst

If you go further and ask the hardware folks what they think, they will... (more)

Beyond the Walls of the Enterprise

Most in IT understand that mobile applications are unique. In terms of development, delivery, and management things just are not quite the same as compared to your typical enterprise application. There are many reasons for these differences including new and different programming models and languages, different application packaging and delivery, different development and testing methodologies, and more. While all of these are interesting and have profound effects, in talking to enterprise IT shops there is one major difference that sticks out a little more than most: mobile ap... (more)

Cloud Computing Intersects IT Innovation

Recently, I attended SOAWorld 2009 in New York City, and I had the pleasure of listening to many distinguished speakers talk about extremely interesting topics.  One of my favorite talks was given by a fellow IBMer, Kareem Yusuf. During the course of Kareem's keynote, he discussed SOA, cloud computing, and areas of innovation in the IT industry. The areas of innovation were of particular interest to me, and Kareem highlighted five of them: 1. Automation and Management 2. Elastic Applications 3. Software Delivery 4. Pricing and Licensing 5. Cloud-based services As I look at each of th... (more)
