The term "architecture group" is a heavily loaded one. I've run into different scenarios at the various clients that have engaged us for consulting on their architecture strategy. In some cases, we have been asked to help seed and grow such a group. In other cases, we've been ask... (more)

The feasibility of adopting new technology in the computing world is governed in large part, as it is in other paradigms, by the cost-benefit-risk equation. In the world of electronic computing, whenever a cost-benefit analysis is done, the benefit/risk of adopting open source so... (more)

One of the biggest barriers to SOA adoption is fear of not meeting the high demands of the runtime environment coupled with the need to provide business agility. As more layers have been introduced by the components of the new technology stacks, the points of failure in distribut... (more)

Ask 10 people the question: What is SOA? You will most likely get 10 different answers. Chances are that in more than 50 percent of the cases, the word "Web services" will be a part of the answer. Another 20 percent will talk about process orchestration, XML, integration, and so ... (more)

It never ceases to amaze me how ambiguity in the definition of simple terms can lead to design choices that have a huge impact on the success of projects. Recently I had a long discussion with a colleague at a client site, where we are in the process of assessing the artifacts th... (more)

As the complexity of enterprise applications grows with the increased offerings in the Java platform, the management of the different building blocks that constitute the application also becomes very complex. The challenge in managing applications in the enterprise is posed from ... (more)

As organizations bravely venture into the world of Web services, they grapple with the age-old question - where do we begin? The main challenge that I have seen with key stakeholders looking to move towards the agile enterprise is solving the dilemma of which approach to take, to... (more)

At JavaOne this year, one of the biggest announcements (albeit this one had nothing really to do with Java) was the acquisition of SeeBeyond by Sun Microsystems. It looks like Sun is putting its cash, which it has plenty of, to good use. As we have seen over the last decade of Ja... (more)

Over the last couple of years, the industry has rallied around SOA and its main realization platform - Web services. While many of the clients I meet are still wary about the adoption of new technology, integration dilemmas posed by the variety of software and hardware platforms ... (more)

As SOA and Web services adoption in the industry is gaining more momentum, the need to get quick wins and to show the value of adopting new (or old) paradigms is weighed against the risk of facing the repercussions of slapping something together in a quick and dirty fashion and p... (more)

If we consider JavaOne as the event when Java was born, then June 27-30, 2005, will mark its tenth birthweek. A lot has happened since the language that was trademarked with dancing dukes made its appearance into the world of computing. In its current incarnation, the Java platfo... (more)
