Mechanisms¶
- Elastic Capacity Scaling
- Tuned too tightly it flaps — adding and removing capacity in oscillation as the indicator crosses the line repeatedly
This sourceExplains that a stabilization window restricts replica-count flapping when scaling metrics fluctuate.

- Service-Level Autoscaling
- When the driving signal lags the true load, or the step is too large, the loop oscillates — the autoscaling analogue of a thundering herd, adding a wave of capacity that lands late, over-corrects, and is torn back out.
This sourceKubernetes Documentation (n.d.). Documents that Horizontal Pod Autoscaler replica counts can fluctuate frequently—thrashing or flapping—and that stabilization windows and tolerances can restrict those unwanted changes.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
