Architectural Patterns

Intermediate routing pattern

How can dynamic runtime factors affect the path of a message?:

Problem	The larger and more complex a service composition is, the more difficult it is to anticipate and design for all possible runtime scenarios in advance, especially with asynchronous and messaging-based communication.
Solution	Message paths can be dynamically determined through the use of intermediary routing logic.
Impacts	Dynamically determining a message path adds layers of processing logic and correspondingly can increase performance overhead. Also, the use of multiple routing logic can result in overly complex service activities.

 

Problem: A service composition can be viewed as a chain of point-to-point data exchanges ...
