Why Enterprise Service Bus
Today's enterprise is not confined to the physical boundaries of an organization.
Open systems and an open IT infrastructure strives to provide interoperability not
only between platforms, runtimes, and languages, but also across enterprises. When
our concerns shift from networked systems to networked enterprises, a whole lot
of opportunities open up to interact with enterprise applications. Whether it is for
trading partners to collaborate through their back-end systems, or for multichannel
deployments where consumers can use a whole lot of user agents like web and
mobile handsets, the opportunities are endless. This also introduces the issues and
concerns to be addressed by network, integration, and application architects. Today,
companies that have been built through mergers or rapid expansions have Line of
Businesses (LOB) and systems within a single enterprise that were not intended to
interact together. More often than not these interactions fail and are discredited.
Let's begin with a quick tour of enterprise integration and the associated issues so
that we can better understand the problem which we are trying to solve, rather than
follow a solution for an unknown problem.
