12 INTEGRATED SERVICE-ORIENTED DESIGN COMPOSITION DIAGRAM
LOGICAL DESIGN COMPOSITION STRATEGIES
Obviously, the logical design composition styles offer service group formations that can facilitate
efficient solutions. Here, the aim is to arrange services based on their message exchange
requirements and to identify the best routing paths for information delivery. But this composition
is also based on the service??™s business affiliations, technical associations, capacity, and
reusability aspects. Thus, a service design composition embodies more than just simple service
relationships. This collection of services can work together, collaborate in interoperable computing
environments, and promote business goals through design strategies.
It may be argued that every group of services that maintains any type of relationship intrinsically
forms a service cluster. It may also be claimed that every logical design composition is a
cluster as well. These assertions are true. Remember, however, that the logical design composition
is the package that is delivered for further architectural assessments and service construction. Thus,
to put things in the right perspective, it would make sense to regard any service group formation as
a cluster. But the logical design composition is the final deliverable and should be conceived as a
structural framework that is packaged for future architecture initiatives.
