9.4 Runbook: Incident Response

P0 Incident: Service Down

1. DETECT: Prometheus alert → PagerDuty page
2. ACKNOWLEDGE: On-call engineer acknowledges (< 15 min)
3. ASSESS: Check Grafana dashboard for scope
4. CONTAIN: Rollback if recent deployment
5. RESOLVE: Restart pods / Scale up / Failover
6. COMMUNICATE: Status page update
7. POST-MORTEM: Blameless RCA within 48h

P1 Incident: High Error Rate

1. DETECT: Error rate > 1% for 5 minutes
2. ACKNOWLEDGE: On-call acknowledges (< 1 hour)
3. INVESTIGATE: Check Sentry for error patterns
4. FIX: Hotfix or feature flag disable
5. VERIFY: Monitor error rate normalization
6. DOCUMENT: Update runbook if new issue

10. Kesimpulan

10.1 Summary Findings

SafeWallet v2 adalah sistem yang fungsional dan relatif aman untuk skala menengah (~1.000 user aktif), namun memiliki batasan skalabilitas kritis yang harus diatasi sebelum scaling ke 10.000+ user.

SafeWallet v3 menunjukkan arsitektur enterprise-grade yang solid dengan microservices, Kubernetes, dan security best practices, namun perlu testing dan validasi lebih lanjut sebelum production deployment.

10.2 Key Strengths

✅ Security-First Design: E2EE, RLS, audit logging, PII redaction
✅ Modern Architecture: Next.js 15, React 19, TypeScript
✅ AI Integration: Gemini 2.0/2.5 with fallback mechanism
✅ Blockchain Integrity: SHA-256 hashing for immutability
✅ Comprehensive Documentation: Well-documented codebase

10.3 Critical Gaps

🔴 OCR Bottleneck: Serverless OCR tidak scalable
🔴 No Load Test Results: Performance limits unknown
🟡 Single Point of Failure: Single region deployment
🟡 Limited Observability: Need enhanced monitoring

10.4 Final Recommendation

Untuk Production Deployment:

1. Immediate (Week 1-2): Execute load testing, document baseline
2. Short-term (Month 1-3): Migrate to v3 async architecture, implement key rotation
3. Long-term (Month 3-6): Multi-region deployment, compliance certification

Risk Assessment:

• Current Risk Level: 🟡 MEDIUM (acceptable for demo/limited production)
• Target Risk Level: 🟢 LOW (after implementing recommendations)
