SERVICE UNIFICATION USE CASE. The two-step unification process is commended by an asset
consolidation request by an enterprise. Consider the following use case, which represents the
business problem domain and the solution proposition.
Business problem domain: the management and maintenance costs of our diverse account offerings owned by
different organizations have been climbing in recent years.
Solution proposition: We should consolidate our small-sized retirement and investment account
services into a larger individual account service.
Exhibit 7.14 illustrates the two-step method for unifying composite services. Step one
depicts the merger between the internal SEP-IRA and traditional IRA services and their total
integration into their parent??”the retirement account service. The second step exemplifies the
merger of three services: retirement account service and investment account service into the
individual account service.
SERVICE UNIFICATION BEST PRACTICES. Special architectural consideration should be given
to avoid the excessive use of the unification operation. In the process of consolidating and
merging assets, the resulting unified service may be too coarse-grained to handle in production
environments. This can impair the reusability aspects of the organization??™s integration activities
and pose service-monitoring challenges. Exhibit 7.15 illustrates the service unification benefits
and best practices discussed thus far.
