Layer – Design Patterns
Service Layers: Related services are designed according to service models, thereby establishing logical service layers. In this case, the service inventory is structured with three service layers that correspond to the three abstraction patterns described in Chapter 7. (Note the pipe symbol is used to represent a service layer in this book.)

Problem

Arbitrarily defining services delivered and governed by different project teams can lead to design inconsistency and inadvertent functional redundancy across a service inventory.

Solution

The inventory is structured into two or more logical service layers, each of which is responsible for abstracting logic based on a common functional type.

Application

Service models are chosen and then form the basis for service layers that establish modeling and design standards.

Impacts

The common costs and impacts associated with design standards and up-front analysis need to be accepted.
