SOA initiatives have gathered momentum in the past year with more enterprises either implementing SOA or considering implementing in the near future. The implementations we studied reveal that one of the critical challenges in SOA is designing an effective governance mechanism. A good ...
Intel Corporation announced Intel SOA Expressway for Healthcare, software that provides a way to exchange healthcare information inside hospitals and with health information networks. The product will allow healthcare providers to connect with one another so that each can provide bette...
Architectures are like archaeology; in essence, layers upon layers of systems, applications, databases, and connections, typically built or procured to solve a tactical problem. Many corporations talk a good game and brag about the strategic long-term direction of the enterprise archit...
SOA (Service Oriented Architecture) is an architectural paradigm that aims to achieve loose coupling and reuse among software components. It's emerging as the main integration and architectural style in today's complex software infrastructure. Web Services aim to provide interoperabili...
So you've decided to invest in Service Oriented Architecture (SOA). You've read up on it and heard the experts proclaim its potential to transform the way your business interoperates. You're excited about SOA's prospects and what it will do to improve the fitness and agility of your co...
SOA has been aggressively hyped by the IT industry as a technology that can - and does - change the very nature of business. In recent times - as you well know - the Internet was a similar technology - and as with the Internet, we at IBM actually believe the hype to be true.
I spent a few hours of my weekend attempting to research and define these concepts a bit better, in essence, taking everyone's opinions and normalizing them so they make better sense. What I found were many of the same notions, defined differently, but all attempting to solve the same ...
I'm consulting now...at the project and strategy levels...and finding that a lot of real work needs to be done to get SOAs up and running. For most organizations, the first step of their SOA project is to figure out how much this SOA will cost. So you can budget appropriately and get t...
Today, global businesses are increasingly turning to Service Oriented Architecture (SOA) for their information technology infrastructure and applications. SOA is becoming an increasingly practiced approach to building software solutions as it can support integration and consolidation o...
The first wave of integrating storage, computing, and networking hardware helped businesses move from client/server to Internet-based peer-to-peer networks. A second wave of integrating applications on top of the hardware infrastructure promised to deliver unprecedented economies of sc...
SCA is a powerful and simple business level programming model that extends prior approaches to be able to implement services based solutions. SCA defines how services can be described, assembled, and deployed in a meta-data driven fashion, independent of an implementation language and ...
Most organizations that have tried have been successful in implementing a pliable Service Oriented Architecture (SOA) paradigm. Analysts have come out with strategies to translate existing applications into SOA-compliant systems using a staggered approach. The rewards reaped come in th...
For several years, software vendors have been creating development and infrastructure products for the latest IT architecture style - Service Oriented Architecture (SOA). Recognizing the immense value SOA can bring to IT, companies like BEA, IBM, and Microsoft have delivered products t...
The main drivers for SOA-based architectures are to facilitate the manageable growth of large-scale enterprise systems, to facilitate Internet-scale provisioning and the use of services, and to reduce the cost of organization-to-organization cooperation - SOA RM
SOA RM: '...in SOA, services are the mechanism by which needs and capabilities are brought together' Recently OASIS voted the SOA Reference Model (SOA RM) into a standard. In spite of its high level of abstraction, this model emphasizes the business orientation of SOA.
The original inspiration for Service-Oriented Architecture (SOA) was vendor neutrality and interoperability among best-of-breed technology components, comprising a cohesive system that is flexible and adaptable enough to meet ever-changing enterprise demands. Yet, recent news from wel...
Right now the implementation of SOAs seems involve much more hype than actual work. However, there are some patterns beginning to emerge, or, procedures the implementers are doing right to insure success. These patterns are not always obvious, so perhaps this is a good time to learn th...
In last month's article, we discussed the motivation for SOA governance and the areas where governance should be applied. We also pointed out that, while SOA governance is not a shrink-wrapped product that you can simply implement off-the-shelf without also addressing important organiz...
The phrase 'SOA governance' is more likely to generate a sense of apprehension among IT professionals than any warm feelings. After all, most companies are still in the early stages of SOA adoption and so the practice of governance - and likely the concept itself - will be new territo...
Service-Oriented Architecture (SOA) is gaining momentum as a new IT implementation paradigm. Organizations are eager to capitalize on its benefits. However, with many of these organizations focusing too narrowly on project-specific implementations, though, some are at risk of never a...
This article is the second part of a two-part series covering best practices for building Service Oriented Architecture (SOA) applications. The following are the seven key steps for effective SOA adoption:
There's no doubt that the computing era of Service Oriented Architecture is upon us. Everyone has caught SOA fever (is it S-O-A or SO-AH?) and most Fortune 500s are considering or have already implemented their first set of services.
An efficient Service Oriented Architecture (SOA) implementation distributes as much processing as possible to trusted appliances in the nearer tiers, where intelligent content-based routing decisions made by highly efficient processors can also perform caching, transformations, and oth...
When designing your SOA and services, keeping the service consumer in mind will make the job easier. Consumers must conform to the interfaces of each service they use and invoke them with the right data in the right format. The more similarity there is among services, the less coding a...
'Our processes are bulletproof. Nothing gets into production that doesn't go through the proper and complete approval process.' Famous last words uttered by far too many enterprise architects. Some of them actually believe it's true - others think that by hoping it's true, maybe, just ...
Agile IT systems are systems that are malleable enough to address business uncertainties. Such systems can effectively respond to internal and external stimuli in a very short period of time. Flexible IT systems imply that the IT architecture underlying them is itself flexible and lend...
Companies are under tremendous pressure to meet the complex business requirements found in their IT infrastructures. For example, they need to expose their applications to external trading partners, comply with government regulations such as Sarbanes-Oxley, integrate merged companies o...
Service Oriented Architecture (SOA) facilitates the development of applications as modular business services that can be easily integrated, secured, and administered. Benefits of an SOA approach include more-rapid development, decreased maintenance and change management costs, and impr...
The quest for agility has spurred the recent rise of Service Oriented Architecture (SOA) and the face of modern IT integration architecture is changing. Technology stovepipes of the past are now being connected by Enterprise Service Bus (ESB) technology, which provides the backbone for...
What is unique about an SOA is that it's as much of a strategy as a set of technologies, and it's really more of a journey than a destination. Moreover, it's a notion that is dependent upon specific technologies or standards, such as Web services and interface technology, but really re...
Ever striving for competitive advantage, organizations frequently turn to information technology. This quest - and the numerous technologies and architectural approaches adopted to maximize the value of the information captured in IT assets - has resulted in a collection of frequently ...
As Service Oriented Architecture (SOA) initiatives attain critical mass in the enterprise, there's more and more interest in boosting business results and competitiveness (not to mention leveraging significant long-term investments) by incorporating mainframe assets into the SOA. Howev...
Service Oriented Architecture (SOA) refers to an architectural solution that creates an environment in which services, service consumers, and service producers co-exist yet have no dependence on each other. SOA enables an enterprise to increase the loose coupling and the reuse of frequ...
What could be easier than to take your application, wrap it with a Web Service, announce it or register it in the UDDI and get a SOA Service? Even better - take a data warehouse, cover a SQL executing code with a Web Service and expose it to SOA, isn't it simple? This article is for th...
It has come to my attention that there are really two kinds of SOA technology vendors out there, old school and new school - each offering very different approaches to solving the SOA problem. I'm not going to mention any particular vendors, but you guys can guess who they are.
While significant attention has been paid to the benefits offered by service-oriented architecture (SOA), which has led to an increased understanding of the challenges that SOA poses as well, far less consideration has been given to the changes that this approach will impart on the IT ...
