Service Oriented Architecture (SOA) facilitates the development of
applications as modular business services that can be easily integrated,
secured, and administered. Benefits of an SOA approach include more-rapid
development, decreased maintenance and change management costs, and improved
business visibility. However, achieving these benefits isn't automatic -
although many early adopters of SOA have been able to realize its promise
fully, others have struggled to find the best architecture and design
patterns for this approach.
The SOA model is about asynchronous, loosely coupled, stateless interactions
through the use of standard component interfaces and architectures. However,
it's often not obvious how this approach should be combined with traditional
development ... (more)
This article is the second part of a two-part series covering best practices
for building Service Oriented Architecture (SOA) applications. The following
are the seven key steps for effective SOA adoption:
Create a portfolio of services Define connectivity and messaging interfaces
Process orchestration, workflow, and rules Rich user interfaces Business
activity monitoring Security and man... (more)
IT architectures have evolved to include process orchestration as a
fundamental layer due in no small part to the emergence and widespread
adoption of the WS-BPEL standard. WS-BPEL, also known as Business Process
Execution Language or just BPEL, is a standard owned by OASIS that provides
rich and comprehensive orchestration semantics. This article will provide a
brief overview of how BPE... (more)
Agile and adaptive business processes and supporting IT infrastructure are
the holy grail of enterprise applications. The industry is heading in the
right direction to start delivering on this promise. SOAs (service-oriented
architectures) promise to enable businesses to align their business processes
to customer needs, and optimize them to improve customer responsiveness and
drive effic... (more)
There's a common misconception that Business Process Execution Language for
Web Services (BPEL) is useful only if all of your systems are Web services.
This article describes how Web Services Invocation Framework (WSIF) enables
BPEL to orchestrate nearly any legacy system as if it were a Web service -
without having to explicitly wrap or publish it as one. It also highlights
how JSR-208 ... (more)
