For a complete list of the co-authors and contributors, see the end of the article. Microsoft's Software-plus-Services strategy represents a view of the world where the growing feature-set of devices and the increasing ubiquity of the Web are combined to deliver more compelling solutions. Software-plus-Services represents an evolutionary step that is based on existing best practices in IT and extends the application potential of core service-orientation design principles. Microsoft's efforts to embrace the Software-plus-Services vision are framed by three core goals: User experiences should span beyond a single device Solution architectures should be able to intelligently leverage and integrate on-premise IT assets with cloud assets Tightly coupled systems should give way to federations of cooperating systems and loosely coupled compositions The Windows Azure platfor...

Introducing SOA Design Patterns

Originally inspired by techniques used to design buildings and cities, and popularized by the Gang of Four during the mainstream emergence of object-orientation, design patterns have seen us through the various shifts in architecture, technology, and, of course, design. Pattern catalogs have periodically emerged, one building on the other, and each revealing a set of problem-solving techniques and providing invaluable insights as to how and when those techniques should be used to help us attain our design goals. SOA has its own history, having risen out of a haze of ambiguity to e... (more)

Cloud Computing, SOA and Windows Azure - Part 3

For a complete list of the co-authors and contributors, see the end of the article. A cloud service in Windows Azure will typically have multiple concurrent instances. Each instance may be running all or a part of the service's codebase. As a developer, you control the number and type of roles that you want running your service. Web Roles and Worker Roles Windows Azure roles are comparable to standard Visual Studio projects, where each instance represents a separate project. These roles represent different types of applications that are natively supported by Windows Azure. There ... (more)

Exclusive SOA Web Services Journal Briefing – Thomas Erl On SOA

With the unwavering prominence of service-oriented architecture (SOA) there is an increasing interest in understanding what exactly it means for something to be considered "service-oriented." Thomas Erl recently completed a lengthy research project for SOA Systems Inc. into the origins of SOA and the current state of service-orientation among all primary SOA technology platforms. This body of work contributed to the mainstream SOA methodology developed by SOA Systems and was also documented in Thomas's new book, Service-Oriented Architecture: Concepts, Technology, and Design. We ... (more)
