• CPU usage > 70%
• Query latency > 100ms

Add Backend Instances when:

• Request rate > 1000/sec
• CPU usage > 80%
• Response time > 200ms p95

Migrate Rate Limiting when:

🔐 Security Hardening for Production

Additional Recommendations

1. Web Application Firewall (WAF)

   • CloudFlare (recommended)
   • ModSecurity
   • AWS WAF

2. DDoS Protection

   • CloudFlare proxy
   • Rate limiting per IP
   • Fail2ban for repeated attacks

3. Database Security

   -- Create read-only user for analytics
   CREATE USER analytics_ro WITH PASSWORD '<strong-password>';
   GRANT CONNECT ON DATABASE fotbal_club TO analytics_ro;
   GRANT USAGE ON SCHEMA public TO analytics_ro;
   GRANT SELECT ON ALL TABLES IN SCHEMA public TO analytics_ro;
   

4. Secrets Management

   • Use environment variables (not in code)
   • Consider HashiCorp Vault for sensitive data
   • Rotate secrets quarterly

5. Backup Strategy

   # Daily database backups
   pg_dump -Fc fotbal_club > backup_$(date +%Y%m%d).dump
   
   # Upload backups (7-day retention)
   # Store offsite (S3, BackBlaze, etc.)
