Mastering Non-Functional Requirements

Impact on NFRs

This lists the impact on NFRs of the Message Bus solution pattern:

NFRs	Description
Availability	On the whole, the availability of the core application is improved due to the Message Bus architecture. If the peripheral application fails, the core application can continue to function.
Performance	Overall system performance is potentially improved. The performance of the applications will also be improved if they are hosted on their own dedicated hardware rather than sharing with the core application.
Scalability	The scalability of the overall system is largely unaltered, but the separation of extraordinary functionality allows it to be scaled independently from the core system elements.
