Des tonnes d'infos intéressantes sur SOA et les Web Services, par Pierre "Orchestra Networks" Bonnet

Ce mois-ci, je vais vous présenter l'univers passionnant de BizTalk Server 2006 et sa prise en charge pour les technologies de services Web d'aujourd'hui. Vous apprendrez à utiliser les adaptateurs SOAP et WSE (Web Services Enhancements) déjà disponibles et je vous parlerai du nouvel adaptateur Windows® Communication Foundation (WCF) inclus dans BizTalk® Server 2006 R2.

The importance of the UDDI standard in the future of SOA is highlighted in a new Burton Group Inc. report, "Registry Services: The Foundation for SOA Governance" by Anne Thomas Manes, research director at the analyst firm. In this interview, Manes explains why after being ignored for so long, the OASIS UDDI standard now at version 3.0, is finally moving up the adoption curve.

Almost everyone has at least heard of SOAP. Few people have heard of REST. But both are jockeying for the mindshare of developers trying solve problems building applications on the web. REST by virtue of existing, and SOAP largely by virtue of backing by software vendors and standards bodies.

Many messages that flow among businesses are formatted to specific industry standards. As we move toward Web services and service orientation the payloads can add value to the messaging infrastructure in a flexible, interoperable, composable way.

Is HTTP GET/POST enough for you? Fine. Then you are simply not the 'right target' for web services evangelists ;-)

Will there be still 97% of simple REST services on the web then? Yes, sure. WS-* does not compete with browser-oriented applications or simple-get-then-do-regexp interactions

my latest Internet Computing (IC) Toward Integration column tries to take a middle ground in the ongoing "REST vs. SOA" debate. It's called "REST Eye for the SOA Guy" (PDF) and it attempts to explain, from the perspective of someone like me with a lengthy SOA background, the benefits that REST brings to the distributed systems picture

acceptable levels of tolerance differ depending on whether or not a given operation is safe or not

it is actually not up to the server to purely dictate a straight process and response to the consumer it is up to the consumer and producer to negotiate the right result for both parties a QoS policy that assumes that the producer is the final arbiter of quality is liable to produce a very unfriendly service and one which doesn't interact with people in the manner which they wish

to implement Web Services Security with the X.509 Certificate Profile, you also need to implement XML Signature (which includes XML Canonicalization and XML Exclusive Canonicalization) and XML Encryption. To correctly handle imports of WSDL1.1 documents (and validate the traffic they describe), you need to support the entire behemoth that is XML Schema -- in particular if you are attempting to support RPC-oriented SOAP, which informally requires you to support the entire XML Schema Datatypes specification. Don't forget support for SOAP with Attachments, either!

Systinet Registry provides a simple and standards-based means for publishing and discovering reusable business services and SOA artifacts. Available as an independent product or as an integrated component of Systinet 2, this enterprise-class registry allows organizations to easily standardize publishing, discovery, approval and interoperability of SOA business services.

It doesn't matter if a partner uses REST or SOAP, he pointed out. "Our developers don't care if it's REST or SOAP. It's all about customers," he said.

This SearchWebServices.com learning guide introduces you to Business Process Execution Language for Web services, or BPEL4WS. In this BPEL learning guide, you'll find articles, tips, expert advice, white papers and more that will explain how BPEL fits into the world of Web services.

This SearchWebServices.com learning guide introduces you to service-oriented architecture, or SOA. In this SOA learning guide, you'll find articles, tips, expert advice, white papers and more that will explain how SOA fits into the world of Web services.

Enterprise integration is a complex field, and there is no simple 'cookbook' answer. Patterns are accepted solutions to recurring problems within a given context. They are abstract enough to apply to most integration technologies, but specific enough to provide hands-on guidance to designers and architects. Patterns also provide a vocabulary for developers to efficiently describe their solution.

ActiveGrid est un environnement de réalisation d’applications WEB totalement intégré qui repose entièrement sur les standards XML les plus récents : BPEL, XForms, WSDL, XML Schema, XACML. L’offre d’ActiveGrid est composée d’un builder et d’un server, tout ça dans une architecture LAMP (le P devant se comprendre essentiellement pour Python).

ActiveGrid Studio makes it easy to create rich, interactive Web 2.0-style applications that integrate your existing databases, applications, and services. The ActiveGrid Studio offers graphical editors and wizards and is based completely on standard XML files so there is no code generation or proprietary metadata.

LogicBlaze, the company behind the (now Apache incubating) ServiceMix ESB and ActiveMQ messaging solution recently announced the availability of FUSE - an Open Source SOA Platform. FUSE is centered on ServiceMix (which I posted on here), aggregating components from several open source projects

LogicBlaze FUSE provides a complete runtime environment for SOA, providing a reliable, scalable and manageable environment for orchestrated Web services, composite applications and event-driven business processes across distributed, loosely-coupled systems and services.

I see lack of contract as the main issue and perhaps even showstopper in enterprise

A couple of years ago Water Supply-Strategic Tactical Air Recycling (WS-STAR) opened up a branch in our town. WS-* (as my IM crazy kids would type) came about from the merger of Secure Operations Air and Power (SOAP) with Expert Machine Lubrication: Radiators, Power, and Cooling (XML-RPC).
