Are You Ready for Mashups?

By Anant Kadiyala. SOA WORLD MAGAZINE, Jun. 28, 2007. With the emergence of Web 2.0 and SOA technologies, mashups have gained in popularity. Web 2.0 provides a rich user experience, and SOA technologies facilitate the underlying flexible plumbing required to make mashups happen. So you could say mashups are a mashup of Web 2.0 and SOA!

Enterprise SOA Adoption Strategies

Book by Steve Jones published on Sep 26, 2006 by InfoQ. Major changes in technology have not been driven by the technologies themselves but by the change in thinking that they enabled. OO design changed software by changing thoughts away from procedures and onto real world "things". This book argues that for SOA to succeed we must move our thoughts away from the implementation technologies and towards the "what" of the business. Using a straight-forward, pictorially driven, methodology the book explains who to discover what the business services really are and how to construct an overall business service architecture.

How To Navigate A Sea of SOA Standards

By Bob Violino, CIO.com. Facing too many emerging standards -- and not enough vendor support for them -- in your service-oriented architecture implementation? Consider these steps in your planning. While the potential benefits of SOA are clear, like the ability to reuse existing assets, the standards picture looks anything but settled. Not only did Forrester Research count some 115 standards floating around SOA and Web services in its most recent study on that topic, but also, it found that just confirming which vendors support which standards is nearly impossible. Yet CIOs must press ahead with SOA projects in order to meet business needs. Hong Zhang, director and chief architect of IT Architectures and Standards at General Motors, has been balancing the standards dilemma with ongoing SOA work for several years.

Is Your Enterprise Architecture Healthy?

David Linthicum: Working directly on SOA projects as an independent I'm exposed to many more organizations than when I was building technology. As such, I see some common patterns or issues emerging.

Web Services Specifications and SOA Interoperability

Interoperability is an important factor in the success of solutions that are based on Web Services and Service Oriented Architecture (SOA), along with other key factors such as contracts, loose coupling, and reuse. Interoperability is generally accomplished by developing your Web Services using the well-established guidelines for implementing Web Services and by following industry standards such as XML, WSDL, SOAP, and UDDI. However, just following Web Services standards and guidelines during the development phase of a project isn't sufficient to achieve interoperability.

Best Practices for Building SOA Applications

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 improved business visibility. However, achieving these benefits isn't automatic - although many early adopters of SOA have been able to realize its promise fully, others have struggled to find the best architecture and design patterns for this approach.

SOA governance and the prevention of service-oriented anarchy

Success with SOA, at an enterprise level, mandates adoption of a robust and disciplined governance framework. Although organizations may differ on the specific functions enabled within their governance model, a common set of capabilities needs to be addressed for SOA. This column discusses the need to build effective governance frameworks while examining customer examples.

Managing SOX in the Age of SOA

Service Oriented Architecture (SOA) is at the heart of many major IT initiatives and vendor offerings. However, while SOA has the potential to deliver business value through streamlined application integration, as well as integration with partners and suppliers, the open nature of SOA has the potential to cause problems with Sarbanes-Oxley compliance. This article will look at compliance issues inherent in developing an SOA. Using a practical example, we'll examine COSO Control Objectives, Risks, and their supporting IT systems from the perspective of Sarbanes-Oxley compliance.

Finally - a standard for Service Oriented Architecture (SOA)

After almost 14 months of intense work, over 6000 messages posted to hundreds of threads, 6 face to face meetings and 34 conference calls by over 225 members and observers from approximately 89 different companies, the first true public standard to describe SOA now exists. The OASIS SOA RM TC closed a final ballot with a successful majority vote to unanimously approve the current draft as an official OASIS Reference Model for SOA Committee Specification. The Reference Model is not itself Architecture, it is more like a template to guide archtiects. Unlike most definitions of SOA which rely on specific examples, the SOA RM is also entirely abstract and not tied to any one technology family or specifications. Those architecting SOA or BPM as the governance layer over top of SOA will probably find it the most useful as it points out the entities and patterns required to allows SOA to work and support the governance layer.

Service Versioning For SOA

(Found in a blog, "Versioning is as inevitable as security.") SOA development practice isn't much different from other software development practices except for design and maintenance. Multiple self-containing and aggregated services that interact with others have their own lifecycle and evolution. The loosely coupling model of SOA services significantly simplifies design but creates additional difficulties in maintenance, especially in the interoperability of different service versions

Readings in Service Orientation

Many forces are involved with architecture, but the fundamental principles that govern all architectures are simple: it’s easy, it works, it’s familiar, and it can be trusted. The purpose of this book is to let you form your own opinions about the impact of services orientation on your business and computing environments. This book is not trying to be an authoritative reference for service orientation. Rather, presented here is an interesting set of classical papers on architecting services by a variety of well-known authors in the architectural space. The topics, or architectural viewpoints covered, go from a perspective on business architecture, through model-based tools, to map from the business to technology to the choices in new IT infrastructure.

Top 8 SOA Adoption Pitfalls

Many SOA initiatives were launched this year, each with its own set of goals and expectations. Some failed miserably, while others failed just a little. For many, the determining factor in fulfilling their original objectives was drawing upon the experience of those who had already survived projects with less fortunate results. These individuals lived to tell their stories and warn others of what lies ahead along the path toward SOA. In our line of work we get pulled into various projects at different stages of completion. We’ve seen good SOA go bad and bad SOA get even worse. Problems can be fixed and mistakes can be undone, but of course there is always an impact to getting things back on the right track. The best course of action is, obviously, avoiding problems and mistakes in the first place. Understanding the pitfalls others have fallen victim to, puts you in a position from which you can form the extent of foresight required to chart a safer route down your own SOA roadmap. To help you get a head start, we have collected the eight most common SOA adoption pitfalls of 2005.

The Four Buckets of SOA Adoption

Jeff Schneider is noticing something really interesting about SOA adoption. You can put the adopters in 4 buckets: 1. Companies that don't do SOA and have no intention of doing it; 2. Companies that don't do SOA but keep talking about it and have mastered the blame game; 3. Companies that do SOA, but poorly; and 4. Companies that do SOA and reap huge benefits

Mainframe to SOA - The People Effect

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. However, if this attention is myopically focused on data and functionality, companies may be overlooking the mainframe's highest potential for rapid time-to-market and ROI: the value of the expertise resident with mainframe developers.

Inducing Behavioral Adaptations Within Web Services

Web services have evolved from plain application-integration enablers to value-added stand-alone functionality providers such as getting a quote to a comprehensive business function like processing orders. Enterprises are exploiting this new revenue model by offering such business functions as services on usage basis. Information sharing instances such as Amazon's e-commerce services have helped in the creation of new powerful solutions using business functions as services.

Trusting Reusable Business Components in SOA and Web Services

One of the business benefits organizations strive to achieve by implementing a service-oriented architecture (SOA) or in utilizing Web services is the opportunity to reuse business components. Asset reuse is one of the core drivers of the SOA or Web service ROI calculation. Although leveraging the service concept provides an avenue for application consolidation and reuse, these same efficiencies also introduce a distinct level of business risk.

Metropolis and SOA Governance

From time to space, the defining technology of the past thousand years was the clock, and the prevailing technological imperative has been to save time to make things go faster or better than before. Approaches to building and governing large, complex service-oriented systems is not unlike designing and managing the complexities of a large city.
