> A design pattern that keeps every service's configuration in one versioned store the services read from.

Listed in [Architecture principles](https://banes-lab.com/api/records/architecture.md), after [Orchestration](https://banes-lab.com/records/architecture/orchestration.md) and before [Centralized Authentication](https://banes-lab.com/records/architecture/centralized-authentication.md).

## Repair

- Refactored by: Move to Central Config, Add Schema
- Detected by: config drift
- Violated by: duplicated divergent configs
- Measured by: config drift count
- Enforced by: config policy

## Requires

- [Config Store](https://banes-lab.com/records/lexicon/config-store.md)
- [Access Control](https://banes-lab.com/records/architecture/access-control.md)

## Reinforces

- [Governance](https://banes-lab.com/records/architecture/governance.md)
- [Consistency](https://banes-lab.com/records/architecture/consistency.md)

## Enables

- [Unified Config Management](https://banes-lab.com/records/lexicon/unified-config-management.md)

## Conflicts with

- [Scattered Configuration](https://banes-lab.com/records/lexicon/scattered-configuration.md)

## In tension with

- [Central Dependency Risk](https://banes-lab.com/records/lexicon/central-dependency-risk.md)
