What Is an Autoscaling Policy?
An autoscaling policy is the configuration that governs how a scaler reacts to load, including the metric it watches, the target value, and the minimum and maximum capacity. It also defines stabilization or cooldown windows that prevent rapid oscillation. The policy translates raw signals into concrete scale-up and scale-down decisions.
Why it matters
A well-tuned policy keeps a service responsive under load without thrashing capacity up and down. On metered managed runners, scaling bounds and cooldowns directly shape how many billed instances run at once.
