adb-infrastructure

Role

Infrastructure-as-code repository for resources that are not in Kubernetes. It manages:

• MongoDB Atlas: migration / setup scripts, configurations via Atlas CLI and Realm CLI.
• AWS EventBridge: external event orchestration rules.

For Kubernetes deployment, see adb-charts. S3 buckets and SQS/SNS queues are currently managed across adb-charts/terraform/ and the AWS console (to clarify).

MongoDB Atlas

Data scripts

mongodb-atlas/data-scripts/ gathers about thirty JavaScript scripts (~37) used to:

• Create / drop collections.
• Index fields (full-text search, geospatial).
• Migrate document structures.
• Seed initial data (catalogues, translations).
• Clean up test collections.

Run manually via mongosh or integrated into data pipelines.

Atlas CLI

The atlas-cli/ subfolder contains configuration files for the Atlas CLI (Atlas command-line tool). It can be used to script:

• Cluster creation / deletion per environment.
• Database user management.
• Snapshots and restores.
• Network access configuration (IP allowlist).

Realm CLI

realm-cli/ configures Atlas Functions (formerly Realm) — serverless functions running close to the database. Used in particular for the MongoDB triggers documented in technical-epics/messaging/i-have-mongodb-trigger.md.

AWS EventBridge

aws/event-bridge/ contains the EventBridge orchestration rules:

• Event patterns (filtering by source, type).
• Targets (Lambda, SNS, SQS, other rules).
• Schedule expressions for time-based triggers.

EventBridge acts here as a router between external events (for instance webhooks from banking partners, electronic-signature notifications) and the internal services through SQS queues.

Databases per environment

MongoDB Atlas hosts several clusters / databases:

• adb-development
• adb-integration
• adb-staging
• adb-production

Naming pattern: mongodb+srv://adb-app:<secret>@adb-<env>.<id>.mongodb.net/.

AWS account: 182790345476 (region eu-west-1).

Notes

• No root Terraform detected. AWS resources outside Kubernetes are managed either via the console, dedicated CLIs, or in adb-charts/terraform/ (Neo4j).
• Eventually, consolidating into root-level Terraform in the monorepo would be desirable for traceability.
