This article discusses the combination of three ideas, virtualization, service-orientation, and grid computing into a single concept and computing platform concept, "virtual service-oriented grids." In addition to history and definitions, the article addresses an approach, with an example, to analyzing and implementing this technology.
With ServiceLayer, adding SOAP and REST web service to your Java applications is as easy as point-and-click... and it can all be done at runtime. By using the graphical user interface, you explore an application, select classes and methods to deploy as services, and your done. Coding is no longer required.
A recent TechTarget survery on SOA adoption from Feburary 2009 shows that SOA is definitely alive and well. Dave Chappell from Oracle agrees that the survey findings match what he sees in the field, as do separate Gartner investigations.
This article introduces and discusses three technologies, virtualization, service orientation, and grid computing, and then shows how they are combining to create new design and deployment options - "Virtual Service Oriented Grids." The business case for using this emergent model is also discussed.
Alex Maclinovsky explains why his vision of Governance differs from those prevailing in the industry. Based on his precise understanding of what a SOA platform should do, he defines a unified view of SOA Governance which he claims "has the potential to take the imperfect SOA platforms and implementations ... and transform them into true Service Oriented Architectures..."
In this presentation, WSO2 co-founder Paul Fremantle talks about the experience of creating an open source SOA registry solution for WS-* web services using RESTful HTTP and Atom/AtomPub and talks about the challenges that were faced. In addition, the talk addresses the use of a pure REST solution by a team with a strong focus on WS-* solutions.
In this presentation, recorded at QCon London, Stefan Tilkov introduces the key principles of REST, explaining the differences to other distributed systems architectures and highlighting its benefits. Topics covered include mapping business logic to resource interactions, hypermedia, and documentation.
Tim Bray talks about why he is not convinced with the buzz surrounding Rich Internet Applications and shares his ideas on Cloud Computing. He also expresses his opinion regarding the debate REST vs. WS-* and the future directions web technologies will be taking.
In this interview, recorded at QCon SF, Stefan Tilkov talks to noted Web services expert and open source developer Dan Diephouse about the benefits of using the Atom Pub and Atom standards for business applications, pros and cons of using REST, and upcoming features of the Apache CXF web services stack.
Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
