kind of conditions lead to such a resolution? There are two major scenarios that justify service
consolidation. The first is the unification of fine-grained services that offer limited business or
technological functionality. This activity typically takes place during the design-time season,
during which services are designed and architected. The second is merging services in production
environments because of reduction in their reusability rates. This is typically due to diminishing
consumer demand for service offerings, leading to difficulty in justifying the operational cost in
a production environment.
It is best to avoid consolidation of services that support a large number of consumers
and are categorized as coarse-grained entities. These are services that execute a large number
of business transactions and functions. In addition, before unification activities are pursued, it
is advisable to examine the business and technological justification for combining services by
analyzing their granularity levels. Service granularity, consumption, and reusability analysis are
discussed in detail in Chapter 7 in the section on Granularity Analysis.
