Unlike the federated domain formation, where control is shared and propagated down
to business constituents, here there is a very loose integration composition that is composed
of self-contained tiers, each of which may be comprised of a single or multiple domains. This
arrangement is best suited for business tiers that do not rely on joint initiatives to contribute to
an enterprise??™s common goal. Individually, however, they manage to provide a valuable source
of revenue to their organizations.
What are the most important aspects when integrating services with domains that are a
part of autonomous business tiers? Should this business integration method be confined to local
domains? Or should an overall organizational business model drive the initiative? Because no
communication protocols and interconnectivity between tiers are needed, the service-oriented
business integration should be localized to each distributed business tier. Thus, each tier, which is
comprised of either a single domain or a number of domain members, is to be treated as a separate
business unit. This integration approach, however, may introduce functionality redundancy and
duplicate service implementations across an enterprise that supports autonomous business models.
Moreover, reusability and consolidation of assets may not be the most important aspect of such
a business constellation.
