It seems like just about every cloud computing discussion with a development audience results in the same question being asked: “Why does this matter to me?” As cloud computing first appears to be primarily an operational-centric paradigm, it is easy to understand the reason this is asked. This question can be answered in a variety of ways. Some may say that cloud computing doesn’t affect the developer in any way, while others will say developers need to totally revamp their skill set to cope with the new landscape proffered by cloud computing. The truth, as always, is somewhere in the middle. Though the industry is still in a bit of disagreement on exactly how to define cloud computing, it doesn’t seem there is a lot of disagreement with the idea of a three-layer cloud. At the top is the Application Services layer, followed by the Platform Services layer, and then ... (more)

The Appliance Form Factor of WebSphere CloudBurst

As with most new technologies, the WebSphere CloudBurst Appliance inspires a healthy set of questions. As usual most of the questions are about features, capabilities, use cases, etc., yet there is one question that is quite frequent but a bit of an outlier from the preceding categories. Personally, I'm not sure I've talked to a group about WebSphere CloudBurst without getting this question. What's the question? "Why is WebSphere CloudBurst an appliance?" It is a very fair question and one whose frequency used to surprise me. I guess I should have seen it coming because save the ... (more)

Catching up with the Cast Iron Team

While many enterprises are expanding their use of off-premise, cloud-based applications and application platforms, it seems some gloss over an important point. These same companies have, and will continue to develop, on-premise applications in both cloud and traditional environments. Considering the ongoing activity in both off-premise and on-premise, it is only a matter of time before a given company has the need to integrate data between their on-premise and off-premise applications. The ability to do this data integration, thereby enabling hybrid clouds or hybrid enterprise a... (more)

A Patterns-Based Approach for Middleware

Yesterday, I joined some colleagues on a webcast where we had a chance to talk to some of our users about the technical concepts behind WebSphere solutions for building, consuming, and integrating clouds. We discussed ways to enable autonomic, policy-driven runtimes, construct elastic, in-memory data grids, and integrate on-premise and off-premise applications. It was all fun stuff to talk about, and hopefully the webcast participants got a good look at how cloud computing is taking hold in WebSphere. Having said that, for me, one topic stood out above the rest and that topic was... (more)

What's the Big Deal About Cloud APIs?

APIs for cloud are important. Based on the number of writings, conference sessions, and Twitter blasts endorsing the cloud API movement, I think this is something on which we can all agree. However, I sometimes get the feeling that we just accept the fact that the API movement is important without really stopping to ask a very basic question: ‘Why are APIs for cloud important?' Now, if you asked this question to a room full of people at say, a cloud conference, you are undoubtedly going to get some amount of variance in the answers. I would wager a guess that the terms automatio... (more)
