In this presentation, recorded at QCon London 2008, Mark Little explains the history of SOAP/WSDL/WS-*-based web services and RESTful HTTP and shows that both approaches have their roles to play in any good architects toolkit. He elaborates on where possible convergence could, or should, occur within the industry.
Despite the extreme importance of transaction processing for ensuring reliability and manageability of distributed computing and several existing WS-* standards, the implementation of the transactional behavior in SOA is still pretty rare. The Reservation pattern, described in a new post by Arnon Rotem-Gal-Oz, provides one of the possible solutions to this problem.
OASIS announced the release of 9 new standards in the WS-* architecture, including new versions of WS-AtomicTransaction, WS-ReliableMessaging and WS-Trust.
IBM, Oracle, Red Hat and others have just announced the formation of the Web Services Test Forum, a venue for continuous testing of interoperability for heterogeneous Web Services implementations as well as a flexible way for vendors and customers to define the interoperability scenarios that are important for them. But how does this relate to WS-I and why has Microsoft not signed up to it yet?
Invariably, learning about REST means that you’ll end up wondering just how applicable the concept really isbeyond introductory, “Hello, World”-level stuff. In this article, Stefan Tilkov addresses 10 of the most common doubts people have about REST when they start exploring it, especially if they have a strong background in the architectural approach behind SOAP/WSDL-based Web services.
Microsoft has intensified its marketing efforts on SOA with the launch of a new web site, a series of webinars, an ebook, “SOA in the Real World” and the “SOA & Business Process Conference 2007”. In the next couple of months Microsoft will also be releasing .Net 3.5 and an ESB Guidance. InfoQ talked to Dino Chiesa, Director of Marketing for .Net to better understand Microsoft's SOA strategy.
Michele Leroux Bustamante explains the most relevant WS-* standards used today in terms of their actual implementation among WS platforms (with a focus on Java and .NET), their level of adoption and readiness. If you are new to web services or to the WS* protocols, or you are having difficulty keeping up with the pace of change in this area, this article should help.
In this interview, recorded at QCon London 2008, Red Hat Director of Standards and Technical Development Manager for the SOA platform Mark Little talks about extended transaction models, the history of transaction standardization, their role for web services and loosely coupled systems, and the possibility of an end to the Web services vs. REST debate.
In this interview, Stefan Tilkov talks to Sanjiva Weerawarana about web services and REST, about core standards that are essential for web services standards, open source SOA tooling, scripting languages and web services, and the strategy of WSO2 in providing open source middleware.
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.
