Introduction This 17th part in our series focuses on new products that let you implement a Service-Oriented Architecture (SOA) life cycle, shown in Figure 1 . (See Resources for information on SOA.)

Architecting on demand solutions, Part 3: Use BPEL to create bus
Introduction Part 3 in this series focuses on the Business Process Choreography Services that were outlined in the On Demand Operating Environment in Part 1 . This article explores how to use BPEL to model a long-running business process that involves integrating services that a bank provides, as well as services that external providers supply. To download the code used in this article, see the download table under the Resources section. odFinance customers use the personal loan application when they want to request a loan.
Architecting on demand solutions, Part 1: Best practices for usi
Introduction The key characteristics of on demand enterprises can be summed up as greater Focus , heightened Responsiveness , Variable cost structures, and improved Resilience . Achieving an increasing degree of on demand characteristics requires fundamental business transformation supported by IT simplification.The nature of a service What then is a service? As previously stated, typically within a business environment, that means business functions, business transactions, and system services.

Web Services and Service-Oriented Architectures
Posts on the Design Decomposition Blog You might have seen the recent news reports about the collision between U.S. and Russian communication satellites. The U.S. satellite was one of the Iridium satellites.
I ask Jay if he recalls an aftershave commercial from a few years back where a man gets a crisp slap on the face but responds by saying, "Thanks, I needed that!" I tell him that's how I feel whenever the subject of SOA security comes up. It's a slap of cold, hard reality that wakes us up to the kinds of serious challenges we have to overcome to fulfill the vision of the SOA.
Security in a Loosley Coupled SOA Environment
In 221B.C., Emperor Qin unified several formerly warring states into a new country, which we now call China. Perhaps one reason China has endured as a nation was Qin’s introduction of standards, which consolidated cultures and facilitated trade: a standard distance for wheels on carts which allowed them to travel efficiently on any road, a common written language that everybody could use to exchange messages (even if they did not speak the same language), and a strong defense against outside attacks (like the Great Wall of China). You could say that he developed the models for standardized transport, message exchange, and the firewall. In the same way, business integration of modern times has benefited from standards that enable heterogeneous computer systems to interoperate efficiently.

OASIS SOA Adoption Blueprints TC
Developing, publishing and maintaining archetypal "blueprint" sets of requirements and functions to serve as generic, vendor-neutral instances of service-oriented solutions for real business requirements. The OASIS SOA Adoption Blueprints TC will develop, circulate, maintain and update a set of example business profiles or "adoption blueprints" to illustrate the practical deployment of services using SOA methods.
In the field of software application development, service-oriented development of applications (or SODA ) is a way of producing service-oriented architecture applications. Use of the term SODA was first used by the Gartner research firm. [ 1 ] SODA represents one possible activity for company to engage in when making the transition to service-oriented architecture (SOA). However, it has been argued that an overreliance on SODA can reduce overall system flexibility, reuse, and business agility . This danger is greater for sites that use an application server , which could diminish flexibility in redeployment and composition of services. [ 2 ]

Einstein made that famous statement many decades ago, and it's still relevant today for building superior software systems. Unfortunately, as anyone who has been in the IT industry for long can point out, far too many software systems have failed Einstein's test. Some are made too simple to carry out the duties they are supposed to perform. Others are made too complex, and the costs of building and maintaining them have rocketed, not to mention the nearly impossible tasks of integrating different systems together. It seems that reaching the right level of simplicity is more like a dream than reality.
The case for developing a service-oriented architecture Over the last four decades, software architectures have attempted to deal with increasing levels of software complexity. But the level of complexity continues to increase, and traditional architectures seem to be reaching the limit of their ability to deal with the problem. At the same time, traditional needs of IT organizations persist; the need to respond quickly to new requirements of the business, the need to continually reduce the cost of IT to the business, and the ability to absorb and integrate new business partners and new customer sets, to name a few.
