- **Management Overhead**: More modules mean more to manage, which can increase administrative burden. 3. **Potential Duplication**: - **Shared Resources**: If there are shared resources or configurations, you might end up duplicatin…

Create a separate module specifically for shared resources like IAM roles. This module can be referenced by both ingestion and retrieval modules. #### Example Structure ``` modules/ shared_resources/ main.tf variables.tf out…
