How does the “graceful degradation” principle impacts on system design?
- Graceful degradation refers to a design principle to ensure that system continues operating although it may have lost some its functions or failed to perform up to standards due to partial failure.
- When a system crashes, it leads to disruption and makes service provision difficult, but when it cracks, it is still serviceable and provides minimal disruption in case the system degenerates.
