Agnostic Context (Erl)
How can multipurpose service logic be positioned as an effective enterprise resource?
Problem
Multi-purpose logic grouped together with single purpose logic results in programs with little or no reuse potential that introduce waste and redundancy into an enterprise.
Solution
Isolate logic that is not specific to one purpose into separate services with distinct agnostic contexts.
Application
Agnostic service contexts are defined by carrying out service oriented analysis and service modeling processes.
Impacts
This pattern positions reusable solution logic at an enterprise level, potentially bringing with it increased design complexity and enterprise governance issues.
Principles
Architecture
Service
The application of this pattern results in a subset of the solution logic being further decomposed and then distributed into services with specific agnostic contexts.
