Large IT organizations increasingly face the challenge of integrating
various web services, applications, and other technologies into a single
network. The solution to finding a meaningful large-scale architecture
that is capable of spanning a global enterprise appears to have been met
in ESB, or Enterprise Service Bus. Rather than conform to the
hub-and-spoke architecture of traditional enterprise application
integration products, ESB provides a highly distributed approach to
integration, with unique capabilities that allow individual departments
or business units to build out their integration projects in
incremental, digestible chunks, maintaining their own local control and
autonomy, while still being able to connect together each integration
project into a larger, more global integration fabric, or
grid.Enterprise Service Bus offers a thorough introduction and
overview for systems architects, system integrators, technical project
leads, and CTO/CIO level managers who need to understand, assess, and
evaluate this new approach. Written by Dave Chappell, one of the best
known and authoritative voices in the field of enterprise middleware and
standards-based integration, the book drills down into the technical
details of the major components of ESB, showing how it can utilize an
event-driven SOA to bring a variety of enterprise applications and
services built on J2EE, .NET, C/C++, and other legacy environments into
the reach of the everyday IT professional.With Enterprise Service Bus,
readers become well versed in the problems faced by IT organizations
today, gaining an understanding of how current technology deficiencies
impact business issues. Through the study of real-world use cases and
integration patterns drawn from several industries using ESB--including
Telcos, financial services, retail, B2B exchanges, energy,
manufacturing, and more--the book clearly and coherently outlines the
benefits of moving toward this integration strategy. The book also
compares ESB to other integration architectures, contrasting their
inherent strengths and limitations.If you are charged with
understanding, assessing, or implementing an integration architecture,
Enterprise Service Bus will provide the straightforward information
you need to draw your conclusions about this important disruptive
technology.
