Logic Centralization (Erl)


Home > Foundational Inventory Patterns > Logic Centralization
How can the misuse of redundant service logic be avoided?  

Problem

If agnostic services are not consistently reused, redundant functionality can be delivered in other services, resulting in problems associated with inventory denormalization and service ownership and governance.

Solution

Access to reusable functionality is limited to official agnostic services.

Application

Agnostic services need to be properly designed and governed, and their use must be enforced via enterprise standards.
Impacts

Organizational issues reminiscent
of past reuse projects can raise
obstacles to applying this pattern.

Principles

Service Reusability, Service Composability

Architecture

Inventory, Composition, Service




Service consumers are required to reuse functionality
provided by a single designated agnostic service.
