Moreover, UDDI registries offer two major types of service-affiliated information: (1) the
supporting business organization information and (2) a technical description of a service.
The rule of thumb suggests that a logical architecture discoverability strategy should be
based on the following asset visibility policy options:
??? Public exposure. Free service discovery access is granted to any consumer, either external
or internal, to an organization.
??? Private exposure. Best suited for an intranet consumer that is internal to an organization??™s
domain.
??? Authorized exposure. Allowed only to an authorized consumer for highly secure and
protected service searching and discovery.
Exhibit 16.10 depicts the discoverability perspective benefits and their corresponding
architectural best practices.
BEHAVIORAL PERSPECTIVE
The behavioral perspective of a service-oriented logical architecture represents a high-level view
of business or technological process implementation. Here, the focus is neither on small-scale business
activities nor on technological details. Remember, these were devised in the service-oriented
logical design phase (Chapter 14). The logical architecture behavioral perspective, however,
merely depicts the type of activities that a technological asset is responsible for. Specifically,
it is required to articulate the major business processes that a technological packaged solution
encompasses, such as a service, a service cluster, a composite service, or any legacy application
it is designed to execute.
