How can agnostic business logic be separated, reused, and governed
independently?
Problem
Bundling both process-agnostic and process-specific business
logic into the same service eventually results in the creation of
redundant agnostic business logic across multiple services.
Solution
An agnostic business service layer can be established, dedicated
to services that base their functional context on existing business
entities.
Application
Entity service contexts are derived from business entity models
and then establish a logical layer that is modeled during the
analysis phase.
Impacts
The core, business-centric nature of the services introduced by
this pattern require extra modeling and design attention and
their governance requirements can impose dramatic
organizational changes.
