# Control Plane

> Descriptive data about the desired state of a distributed runtime, held in one place and applied to every node through a management interface.

Record: `architecture:control-plane`
Kind: artifact
Layer: [Execution Core](https://banes-lab.com/records/layer/execution-core.md)
Severity: contextual
Scope: platform, infrastructure, distributed system
Canonical: https://banes-lab.com/ontology#architecture-control-plane

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Consumer-Driven Contracts](https://banes-lab.com/records/architecture/consumer-driven-contracts.md) and before [Orchestration](https://banes-lab.com/records/architecture/orchestration.md).

## Repair

- Refactored by: Add Control Plane, Externalize Policy
- Detected by: manual node/service control
- Violated by: unmanaged distributed configuration/control
- Measured by: control coverage, control-plane availability
- Enforced by: platform architecture

## Requires

- [Management API](https://banes-lab.com/records/lexicon/management-api.md)
- [Policy](https://banes-lab.com/records/lexicon/policy.md)
