# Scheduled Scaling

> Pre-warm HPA targets before predictable traffic bursts by overriding minReplicas during time windows.

The Scheduled Scaler overrides HPA `minReplicas` during defined time windows — pre-warming
pods before predictable traffic bursts.

**CRD:** `ScheduledScalePolicy` (namespaced)

## Example

```yaml theme={null}
apiVersion: ops-ai.io/v1alpha1
kind: ScheduledScalePolicy
metadata:
  name: morning-burst
  namespace: xano-tenant
spec:
  hpaName: backend-hpa
  mode: active
  windows:
    - name: morning-login-surge
      minReplicas: 50
      preScaleMinutes: 5
      scaleUpSpeed: Instant
      disableScaleDown: true
      schedule:
        type: Weekly
        startTime: "08:30"
        endTime: "10:30"
        timezone: "America/Los_Angeles"
        daysOfWeek: [Monday, Tuesday, Wednesday, Thursday, Friday]
```

Each window can raise `minReplicas`, pre-scale ahead of the window (`preScaleMinutes`),
and optionally override the HPA's scaling behavior for the duration of the window. Original
values are saved and restored when the window deactivates.

<Note>
  For the full set of HPA behavior overrides a window can apply — scale-up/down speed presets,
  `disableScaleDown`, CPU target — see [HPA Behavior Overrides](/platform/scheduled-scale-behavior).

## Dashboard

The **Scheduled Scales** page shows all policies with active-window status and activation
history — so you can confirm a window actually fired.
