EPR and SOA / POA

["David RR Webber" <david@drrw.info>]

Seems like the EPR message is resonanting with people.

Of course EPR is still providing more - but good to see

the mainstream being to "get it".

 

Thanks, DW

 

POA: Building SOA from the Ground Up. Moving Process to the Forefront.
Shone Sadler, Web Services Journal

As technologists today, we face a uniquely challenging paradox. On the
one hand, Web services have created renewed excitement for service-
oriented architectures (SOA) as the answer to common integration
problems; on the other hand, today's application platforms (J2EE & .NET),
used to implement SOA applications, are often deemed overly complex,
and a barrier to widespread SOA adoption. While the primary goal of the
industry is to make the concepts and benefits of SOA mainstream, we
must recognize that SOA itself must evolve to facilitate such
widespread adoption. Fundamentally, we must move from focusing on the
integration aspects of SOA (the "band-aid") to focusing on how to build
applications based on the principles of SOA (the solution); that is,
applications that are inherently interoperable. In this article we
discuss how the convergence of several key technologies is essential
to taking SOA mainstream, and how process-oriented architectures (POA)
are evolving to meet this need by providing a more detailed version of
SOA that derives its fundamental purpose from a process-oriented view
of application development.
