Mastering Non-Functional Requirements

Drivers

Drivers for the Message Bus solution pattern include:

• Low complexity: Complexity is reduced because each application only communicates with the bus, and the bus, in turn, is integrated with the other endpoint applications
• Extensibility: Applications can be added to or removed from the Message Bus without impacting the existing architecture.
• Loose coupling: As long as applications expose interfaces via the Message Bus, there is no dependency on the application, allowing updates, changes, and replacements.
• Flexibility: The set of applications that make up the entire organizational landscape can be easily changed to fit changes in business requirements, simply through changes in the configuration or parameters.
• Simplicity: Although ...
