5 ISOLATED DESIGN RELATIONSHIP
INTERNAL DESIGN RELATIONSHIP. Messages are not only being passed between autonomous,
self-contained, independent service clusters, or distributed consumers, they also can be exchanged
between internal members of aggregated structures. That is, this activity occurs between internal
services that are part of a larger, coarse-grained service formation. Therefore, these associations
are typically maintained on the inside, and there are no outside consumers or services
in this relationship. This design relationship is designated as internal because of the internal
dynamic collaboration between contained services to enable interaction ???privacy??? in aggregated
structures.
