Service
Oriented Architecture (SOA) conceives
systems as a set of services that
are invoked by applications configured
to design an automated business
process. In this current SOA model,
the assumption of universal connectors
has changed. The end points of
source and target applications
are not bound by the rules of
infrastructure i.e. formats, identifiers
and protocols. The endpoints of
systems could be on a true “network”
across different application servers,
operating systems, languages and
traditional network boundaries.
This new way of communicating
using generic identifiers, formats
and protocols following industry
standards can be termed as “Web
Services”.
SOA is all about integration. It puts “integration” as
the core of application building rather than
the traditional overlay approach. The Return
on Investment or Value on an “integration” system
can be expressed as the cost of not having
to duplicate data and application functions.
