Process Centralization (Erl)


Home > Inventory Centralization Patterns > Process Centralization
How can abstracted business process logic be centrally governed?  

Problem

When business process logic is distributed across independent service implementations, it can be problematic to extend and evolve.

Solution

Logic representing numerous business processes can be deployed and governed
from a central location.

Application

Middleware platforms generally provide the necessary orchestration technologies to apply this pattern.
Impacts

Significant infrastructure and
architectural changes are imposed when
the required middleware is introduced.

Principles

Service Autonomy, Service Statelessnes, Service Composability

Architecture

Inventory, Composition




Task services can continue to be implemented as separate Web services, but as part of an orchestration platform their collective business process logic is centrally located and governed (resulting in "orchestrated" task services).
