## Risk Mitigation

### High Risk Items
- Genesis configuration: Test thoroughly before deployment
- Image versions: Verify compatibility before pinning
- Secrets: Use Azure Key Vault from the start
- Application Gateway: Test with staging environment first
- Health checks: Verify with actual Besu deployment

### Medium Risk Items
- Monitoring: Start with basic setup, expand gradually
- Security: Conduct security review early
- Testing: Implement testing incrementally
- Documentation: Update as you go

## Timeline Summary

- **Week 1**: Critical fixes
- **Weeks 2-3**: High priority items
- **Weeks 4-6**: Medium priority items
- **Weeks 7-8**: Production readiness

**Total Timeline**: 8 weeks to production readiness
