Windows Azure Platform Overview The Windows Azure platform is an Internet-scale cloud computing services platform hosted in Microsoft data centers. Windows tools provide functionality to build solutions that include a cloud services operating system and a set of developer services. The key parts of the Windows Azure platform are: Windows Azure (application container) Microsoft SQL Azure Windows Azure platform AppFabric The infrastructure and service architectures that underlie many of these native services (as well as cloud-based services in general) are based on direct combined application of Stateful Services [786] and Redundant Implementation [766]. This is made possible by leveraging several of the built-in extensions and mechanisms provided by the Windows Azure platform (as ex... (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)

Paths to SOA

Many are comparing notes on two well-publicized paths to achieving SOA. The bottom-up approach is currently the most common variety, where Web services are created on an "as need" basis to fulfill mostly integration-related requirements. These services are typically application specific and simply re-create traditional integration channels over the open Web services communication framework.

The key to a successful transition is to find a spot of calm amidst the storm of activity surrounding SOA, and develop an intuitive plan that will guide your organization through a path of technical obstacles, organizational resistance, and ever-shifting industry trends. Count yourself lucky if you've had the foresight to coordinate your migration ... (more)

Cloud Computing, SOA and Windows Azure

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 expe... (more)
