7 GRANULARITY ANALYSIS AND SERVICE METAMORPHOSIS
Aggregation Analysis 139
AGGREGATION ANALYSIS
Aggregation is the discipline of collecting related fine-grained services and including them in a
larger and coarse-grained service. This repetitive process that typically persists during the life
cycle expands the hosting service??™s internal functionalities with each addition to its underlying
business or technical capabilities. In fact, such gathering activities always yield growing composite
formations. Aggregation operations typically increase the scope of the original planned
solution and propose a wider range of remedies to the problems that we are trying to resolve.
This evolutionary process must often be reevaluated to control maintenance cost, mitigate management
challenges, and optimize return on investment. Furthermore, aggregation analysis also
provides the mechanism to augment composite service and service cluster processes by including
supplementary services. This enhances the manipulation of composite and cluster dimensions and
their capability to provide collective remedies to organizational problems.
SERVICE AGGREGATIONPROCESS AND APPROACH. The aggregation4 process is fairly straightforward,
but it requires prior planning to achieve effective results. Remember, the analysis process
makes it possible to evaluate whether the proposed solutions are indeed feasible and whether
the offered remedies can cover the problem domain.
