Multi-Country Tech Stack

Architecture Decisions: - Multi-region cloud deployment - Data residency requirements - Latency optimization - Disaster recovery planning

Recommended Approach: ``` Core Infrastructure (AWS/GCP/Azure): - Primary region: France (Paris) - Secondary regions: Frankfurt, London - CDN for static assets - Multi-region databases where needed ```

Compliance and Security

GDPR Compliance: - Single framework advantage - Data processing agreements - Privacy by design - Cross-border data flows

Industry Regulations: - Financial services (PSD2, MiFID) - Healthcare (country variations) - E-commerce (consumer protection) - B2B (commercial law differences)
