Welcome!


Reducing the cost of IT management is one of the primary pressures for most organizations. One of the most common ways to reduce such costs is to enable the reuse of applications that developers have already created and configured for the enterprise. In the past decade, especially in t...
Cloud computing is slowly gaining credibility and traction in the enterprise world. As giants such as Google and Amazon productize their massive cloud infrastructures, moving enterprise applications to the public cloud seems a more realistic possibility. The advantages of an enterprise...
We can visualize resource starvation using an elaborate rendition of the Dining Philosophers Problem. This classic metaphor of resource allocation among processes was first introduced in 1971 by Edsger Dijkstra in his paper “Hierarchical Ordering of Sequential Processes.” It’s been a m...
Many enterprises are working with service-oriented architecture (SOA) initiatives using a variety of approaches. Regardless of the specific approaches undertaken, the intent is to build services and business processes for the organization to realize the benefits of SOA. However, you ne...
System architects and engineering teams are designing increasingly complex embedded systems in order to satisfy their customers’ stringent functionality and performance requirements. In addition, within tactical systems, it’s not uncommon to require deterministic real-time behavior whi...
In today’s economy, an enterprise must have strong financial motives for transitioning to SOA. SOA’s superior technical capabilities are a strong motive for information technology professionals to make that transition. However, enterprise stakeholders are motivated by solid investment ...
In the enterprise IT environment today, modern middleware technologies make it easier to expose existing or new business applications as sets of services. However, with the mashup of cloud-based services and enterprise data center services, the visibility of how a service created today...
This article explains how an Open Source SOA Roadmap can use a typical Web application project’s funding as the basis for a successful SOA transition effort. It is the first of three articles that explains how open source technologies and techniques can be leveraged to successfully del...
Online commerce is no longer just for consumer products, but also for direct and indirect goods and services. As a result, new demands are placed on classic customer relationship management (CRM) applications. While most have successfully automated customer-facing interactions (such as...
The value of service-oriented architecture (SOA) is the concept of agility, or the ability to limit risk by managing change. Today, many enterprises are fighting to make this a reality, yet few approach SOA using the right methodologies and technology, and most have yet to define the r...
According to Moore’s Law, processing speed and storage capacity have been doubling about every two years since the invention of the integrated circuit in 1958. Yet it seems that our propensity for building larger more complex software systems that anticipate these improvements inevitab...
As consumers we are accustomed to the end-user experience of the Internet. With HTTP and XML, you don’t need to have a specific application on your computer to make use of external data – you can just open a browser window and do a search or visit a particular Web site to find the info...
It’s always good to get an idea of the big picture before diving into the details of any technology-centric topic. For this reason, we’ll take the time to briefly mention the overarching goals and benefits associated with service-oriented computing as they relate to Web Service contrac...
When Enterprise Architecture is able to prove that it can bridge the business vision to IT’s tactical operations, its function will no longer be Hype and EA staff members will no longer need to Hope they won’t be cut. Enterprise Architecture will become an organization without which th...
The Java Community Process requires the development of not only technical specifications, but also Reference Implementations (which prove that specs can be implemented) and conformance test suites (Technology Compatibility Kits or TCKs), which are used to verify that implementations co...
Recently industry analysts, press, and bloggers have been writing about the state of service-oriented architecture (SOA) and whether it’s “dead” or in the “trough of disillusionment." These discussions have been fueled by surveys that suggest a decline in the number of organizations co...
Whenever IT professionals discuss the benefits of SOA – full utilization of IT resources, reduced infrastructure costs, and the agility to deliver new services quickly – they usually issue a caveat. They warn potential adopters of the inherent complexity of SOA, and point out that unle...
For many people, even entire organizations, the approach to education seems to be along the lines of learning facts, figures, details, tools and standards. This results in a shallow understanding of both the business problem and the new Service Oriented Architecture (SOA) strategies av...
SOA is continuing to gain widespread adoption and find success beyond pilot and project implementations, according to recent surveys. There is a steady increase in organizations moving to enterprise-wide SOA deployments. Those that have found success maturing to large-scale SOA have on...
The definition of remote working is changing. Whether an employee is telecommuting or working at a branch office, they require the same connectivity to headquarters, to each other, and to business applications such as inventory and sales data. Many SMEs use the Internet to provide conn...
The health care industry, including hospitals, has the greatest need for sophisticated information systems because of the enormous amount of data it handles and because of its life-and-death responsibilities. Yet the implementation of large-scale and robust-enough IT systems in public ...
A picture is worth a thousand words. We all have heard this saying a countless number of times. But what if you don’t understand what is drawn in the picture? I was approached once with a request to review requirements specifications for some module. The document contained a scheme tha...
One of the key concepts to consider when talking about services and cloud computing is the notion of coupling. We need to focus on this since, in many instances, coupling is not a good architectural choice considering that the services are not only hosted within separate data centers, ...
There is a lot going on in the cloud computing space, and SOA is clearly along for the ride. Indeed, there are many things that cloud computing providers (and that’s a rather big category these days) and those building SOAs can learn from each other. I’m just scratching the surface her...
Application servers, those dependable workhorses that run most enterprise Java applications, are rarely a hot topic of conversation these days. As a technology category, the application server appears to be fairly “established” and that the focus has moved elsewhere in the stack, but a...
I wrote in my previous article, “Interactive Storyboarding with JSP,” that interactive storyboarding is an effective way to define better requirements by eliciting actual business user needs. And I proposed to describe the requirements inJSPs with the J-CASE tag library, which enables ...
Server, storage and site migrations have always been the elephant in the room. IT managers know that it is necessary to reduce costs and improve workload management but cringe over the potential impact to production. In the past, migrations have usually required significant planning, d...
A service inventory is a living body of services that individually will need the freedom to evolve independently over time. What we learned when documenting the SOA design pattern catalog is that there are patterns that emerged not only at design-time but also during this post-implemen...
The rise of Enterprise Architecture (EA) should be no surprise to any of us, and yet every day businesses either opt out of deploying enterprise architecture, or can’t deploy it effectively. While the Industrial Age was characterized by process-based advances such as assembly lines and...
The increased manageability, reliability, and opportunities for reuse promised by a SOA can only be fulfilled with an effective governance structure in place to coordinate service creation, maintenance, provisioning, and consumption. However, many small and medium-sized organizations s...
Storage virtualization for the sake of storage virtualization isn’t enough these days. Being able to pool heterogeneous resources and migrate data from point A to point B while the application is up and running is pretty cool, but what businesses really need are complete solutions – so...
Part 1 of this interview talked about spaghetti and lasagne. Part 2 focuses on ESB, SOA, and the importance of thinking of the business first and last. This is the second part of a two-part interview with Peter Hermans, noted SOA consultant and former architect at a major European tele...
SOA consultant Peter Hermans oversaw a major SOA implementation at a large European telco. Now he talks about what he learned, and what you can learn as you get involved with SOA. Spaghetti and lasagne are involved. This is the first part of a two-part interview.
The 80/20 rule has negative implications for traditional IT reousrce allocation, with the 80 percent going to maintenance, and only 20 percent to innovation. How can you innovate with SOA to flip this ratio on its head?
Think in terms of all of your IT assets as part of a portfolio of innovation, and it becomes easier to think of you to put them to creative use that drives operational efficiency.
Like data normalization, the Service Normalization pattern is intent on reducing redundancy and waste in order to avoid the governance burden associated with having to maintain and synchronize similar or duplicate bodies of service logic. When designing data architectures, you can easi...
As SOA moves from the project level to the enterprise, SOA architects and practitioners quickly realize the need to consider common services and data management issues. Today we seek the right approaches and the proper enabling technology and standards to provide our enterprises with a...
Business and government agencies execute better when they make decisions based on complete and accurate information. However, amassing flawless information becomes more challenging as entities evolve. As organizations expand into multiple geographies, their information assets become fr...
Industry research shows that while many companies believe SOA is beneficial, only a few have reached a level of maturity that lets them to reap real benefits. The relative immaturity of SOA across IT organizations, however, presents an opportunity to structure the SOA program in the mo...
Service-oriented architecture (SOA) has captured the attention and energy of CIOs across the globe given its tantalizing promise of IT agility and business responsiveness. As more companies look to bring the benefits of a SOA approach to their IT processes, a clear pattern of adoption ...
