Overview & Core Principles

Welcome to the #divisions internal knowledge base. This document serves as the single source of truth for our platform's design, operational standards, and team structure.

Core Engineering Principles

• Divide & Orchestrate: Build small, autonomous services with clear boundaries and robust inter-service communication.
• Observability First: Every component must emit structured logs, metrics, and traces from day one.
• Zero-Trust Security: Assume breach. Authenticate every request, encrypt data in transit/at rest, and enforce least-privilege access.
• Automate Everything: If a process runs twice, automate it. Infrastructure as Code is mandatory.

System Architecture

The #divisions platform follows an event-driven microservices architecture hosted on Kubernetes. Core components include:

┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│   API Gateway    │────▶│   Service Mesh   │────▶│   Core Services  │
│   (Kong/NGINX)   │     │   (Istio)        │     │   (Node/Go/Python)│
└─────────────────┘     └─────────────────┘     └─────────────────┘
        │                       │                        │
        ▼                       ▼                        ▼
┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│   Auth Provider  │     │   Event Bus      │     │   Data Layer     │
│   (OAuth2/OIDC)  │     │   (Kafka/Rabbit) │     │   (Postgres/S3)  │
└─────────────────┘     └─────────────────┘     └─────────────────┘

All services communicate via gRPC internally and REST/GraphQL externally. The event bus handles async workflows, order processing, and audit trails.

Technology Stack

Deployment & CI/CD

All deployments follow the GitOps workflow. Push to main triggers automated tests, security scanning, and progressive rollout via ArgoCD.

    branches: [main]

    runs-on: ubuntu-latest
    steps:
      - run: argocd app sync ${{ vars.APP_NAME }}

Security & Compliance

#divisions maintains SOC 2 Type II and ISO 27001 certifications. Key operational policies include:

• Secrets Management: All secrets stored in HashiCorp Vault. Never commit credentials to Git.
• Access Control: RBAC enforced across all systems. MFA required for all admin consoles.
• Data Retention: PII encrypted at rest. Automatic purging after 7 years unless legal hold applies.
• Vulnerability Scanning: Automated SAST/DAST on every PR. Critical CVEs must be patched within 48 hours.

FAQ & Troubleshooting

Q: How do I request access to production databases?

Submit a request via the internal Access-Request Form. Include business justification and expected duration. Approvals take 1-2 business days.

Q: Why is my PR stuck in the security scanner?

Common causes: uncommitted local env files, outdated dependencies with known CVEs, or missing license headers. Run npm run security:check locally before pushing.

Q: How do I rotate API keys?

Use the Vault CLI: vault write secret/api-keys/{service} key="<new-key>". Notify the team in #ops-alerts and update documentation.
