This standard ensures all infrastructure modules are versioned and maintain backwards compatibility, enabling safe and predictable evolution of infrastructure. It reduces disruption and supports collaborative, multi-team environments.
Aligned to our "Infrastructure as Code (IaC) & Policy as Code" policy, this standard enhances stability, reusability, and trust in automation. Without it, changes can break dependent systems and increase operational risk.
| Category | Description |
|---|---|
| People & Culture | Teams use infrastructure code inconsistently. Versioning is not discussed or shared. |
| Process & Governance | No process exists for managing module changes. Breaking changes are introduced unknowingly. |
| Technology & Tools | IaC code is stored locally or manually copied across teams. |
| Measurement & Metrics | No visibility into module usage or change history. |
| Category | Description |
|---|---|
| People & Culture | Some teams use versioning schemes informally. Sharing is ad hoc and undocumented. |
| Process & Governance | Module updates are peer-reviewed but may not check for compatibility. |
| Technology & Tools | Versioned repositories begin to emerge. Semantic versioning is inconsistently applied. |
| Measurement & Metrics | Module usage is partially tracked through manual inventory or tagging. |
| Category | Description |
|---|---|
| People & Culture | Teams align on shared practices. Versioning and compatibility expectations are clearly communicated. |
| Process & Governance | Semantic versioning is standard. Backward compatibility is a required checkpoint. |
| Technology & Tools | Modules are published to internal registries with clear version tags and changelogs. |
| Measurement & Metrics | Compatibility issues are tracked across deployments. Usage patterns begin informing refactoring. |
| Category | Description |
|---|---|
| People & Culture | Teams understand how versioning impacts downstream consumers. Collaboration spans across squads. |
| Process & Governance | Version updates trigger automated pipelines and impact analysis. |
| Technology & Tools | Tools verify compatibility and warn of unsafe changes. Consumers are alerted before upgrades. |
| Measurement & Metrics | Metrics include upgrade frequency, compatibility issues, and reuse across teams. |
| Category | Description |
|---|---|
| People & Culture | Teams co-design shared infrastructure modules. Practices are continuously improved. |
| Process & Governance | Versioning is integrated into governance frameworks. Deprecation policies are automated. |
| Technology & Tools | Feedback loops support dynamic compatibility testing. Self-service tooling supports safe adoption. |
| Measurement & Metrics | Module maturity, drift, and technical debt trends are visualised and used for prioritisation. |
