Thus, the landscape that is about to be established
is architecturally logical. This environment is depicted by the associations between the packaged
technological assets, their behaviors, and the integrated structure that they collaboratively form.
The focus is on a service-oriented integration strategy.
LOGICAL ARCHITECTURE BUILDING BLOCKS
What are the fundamental pillars and supporting entities of a service-oriented logical architecture?
Recall that a service-oriented logical architecture does not involve the treatment of individual services,
nor does it address service associations and the challenges of their internal structures. It
certainly does not address third-party product capabilities. The logical architecture paradigm is
about creating an integrated technological environment that consists of service-oriented assets,
such as services, legacy applications, middleware, platforms, third-party vendor products, management
and monitoring tools, and more. These are the technological assets that are the fundamental
building blocks1 of a service-oriented logical architecture.
Thus, logical architecture is simply a plan to depict the deployment, integration, and behavioral
perspectives of the packaged solutions. This strategy is driven by three major deliverables
furnished earlier in the service-oriented life cycle, listed as follows:
1. Conceptual architecture artifacts. A service-oriented conceptual architecture model
(discussed in Chapter 15) should provide a coherent direction and road map for the
logical architecture.
