# Auto-Scaling

Record: `arch:auto-scaling`
Kind: capability
Layer: [Correctness Core](https://banes-lab.com/records/layer/correctness-core.md)
Severity: contextual
Scope: deployment, service, infrastructure
Canonical: https://banes-lab.com/ontology#arch-auto-scaling

## Repair

- Refactored by: Add Scaling Policy, Make Service Stateless
- Detected by: saturation under load without scale policy
- Violated by: manual-only scaling for variable load
- Measured by: scaling latency, saturation rate
- Enforced by: infrastructure-as-code policy

## requires
