A collection of some nice and interesting postings all around the Web services architecture and SOA:
Rebecca Dias: Service Oriented Architectures, broadband, and outsourcing Do not only think and talk about core technology. Never forget the business or social life impact of all the nice stuff we are doing - and particular what is still coming.
However, many people appear to be missing an important point - namely that "web services" is no more than a tag that marketing people have put onto a radical shift in technology; and, as usually happens in such cases, the marketing obscures some important facts. [...] One of the strongest technology models to emerge over the past few years has been the idea of an "enterprise service bus". Applications can plug into this bus and information can travel along it, goes the theory. But issues of connectivity are holding back deployment of such systems. Currently there is no generally accepted standard, so firms must decide which types of interface to use, which leaves the systems less open.
But I somehow cannot fully agree with his view about the 'unviersal interface language'. He talks about WSDL being something like a healer, but we all should know that WSDL is just a part of a set of metadata description standards (add WS-Poilcy e.g.). Not to mention the still existing but in the meantime no longer so loud heard wishes for the dead of WSDL ... So when reading his article do not take every single sentence and word for face value, IMHO.
Clemens Vasters: "Services" in SOA Read it, think about it - wait another one or two years to see things actually in action ... great stuff!
We can already see the form the next generation of core Web services will take. Delivery will be expanded to include more robust asynchronous messaging, clearer standards for addressing messages, a full-fledged Web service layer message routing system, and more advanced security facilities. Description will be enhanced by the addition of sophisticated policy description capabilities. And discovery will be enhanced with facilities to allow Web services to be dynamically queried for a description of their capabilities. The addition of asynchrony, security, reliability and addressing information into delivery, WS-Policy into description, and URI-based metadata exchange into discovery rounds out what BEA considers to be the next level of core Web service specifications.
