Fallback Strategy
A mechanism that automatically switches to a backup model or cached results when the primary model times out or is unavailable, in order to maintain service availability; it is typically managed centrally at the service framework layer.
Timeline (last 90 days)
A degradation strategy refers to automatically switching to a backup model or cached results when the primary model times out or is unavailable, in order to ensure service availability.
When the decision service is unavailable, the application must not simply collapse; fallback strategies need to be prepared: caching the most recent decision result, setting local fallback rules, or directly allowing non-critical decisions through.
The choice of degradation strategy for the approval layer depends on the reversibility and scope of impact of the operation; for example, irreversible operations such as deleting production data should generally be blocked by default, while low-risk read-type operations can be considered for release.
When the primary channel fails, the backup channel must be able to independently complete the core task, rather than merely reproducing the same failure in a different form.
Engineering capabilities such as resilient design, degradation strategies and human takeover channels will gradually move from bonus points to entry thresholds.
A robust search system should gracefully degrade to basic retrieval when a certain stage becomes unavailable, rather than failing entirely.
