Case Study: EHR Healthcare Migration
Scenario: EHR Healthcare needs to migrate their patient portal from on-premises to GCP while meeting HIPAA compliance. The portal handles 50,000 daily users with strict availability requirements.
Requirements:
- 99.99% availability for critical components
- Data residency for EU patient records
- DDoS protection for public-facing services
- Audit logging for all PHI access
Recommended Architecture:
Compute: Regional GKE clusters across 3 zones with auto-repair and auto-upgrade enabled
Data: Cloud SQL with cross-region replicas for EU data residency
Security: Cloud Armor + VPC Service Controls perimeter around PHI data
Monitoring: Cloud Audit Logs + Security Command Center for compliance reporting

Case Study: Mountkirk Games Analytics
Scenario: Mountkirk Games needs a real-time analytics pipeline for their new multiplayer game expecting 1M+ concurrent players.
Requirements:
- Process 100,000 events/sec with <1s latency
- Anonymize PII before storage
- Support both real-time dashboards and historical analysis
- Cost-effective storage for 90-day retention
Recommended Architecture:
Ingestion: Pub/Sub with 1000+ subscriptions for parallel processing
Processing: Dataflow with DLP API integration for PII anonymization
Storage: Bigtable for real-time + BigQuery for analytics
Visualization: Looker for business users + Data Studio for custom dashboards
