SOA and Web 2.0: Converging and Evolving


Interoperability is accomplished very differently in Web 2.0 than it is in
formal SOA.  Web 2.0 adherents tend to let others integrate with them using
Web-Oriented Architectures (WOAs) based on REST, JSON, and POX/HTTP more
than the SOAP approach that enterprises often prefer.  SOAP is the
underpinning standard of the majority of SOAs, and complex variants
collectively known as WS-* are on the way to increase SOAP's features for
the enterprise by adding transactions, policies, advanced security, routing,
and much more.  


Key point: Far beyond the world of acronyms, Web 2.0 is focused on using
lightweight integration for a larger purpose; 1) low-barrier formation of
communities and 2) enabling two-way use of information technology to create
vibrant online ecosystems of people and their relationships and knowledge.

In addition, the Web itself continues to grab an increasingly larger share
of the software architecture discussion.  Technologies or approaches which
don't align themselves closely to the way the Web works will find increasing
impedance for acceptance.  Ajax is an example of it and is a extremely
useful technique that provides zero-foot, rich software to the browser with
nothing more than what can be found in any Web client.  

Finally, the Web 2.0 way of designing, testing, and maintaining software,
particularly the support of recombinant software by the virtue of simple
Javascript includes (client-side mashups) or simple, granular REST-style Web
services, is faciliating the growth of a rising Global SOA or mashosphere.
Lightweight Web services and syndication models like RSS and Atom are
creating an information ecosystem that has virtually no barrier to
consumption and integration.  Essentially, with techniques that provide the
right fertilizer, the Web garden has fostered better solutions for many
integration scenarios than upfront design.
