Deployment Guide

This guide covers production deployment strategies for faneX-ID, including high availability, scaling, and best practices.

Deployment Strategies

Single Server Deployment

Use Case: Small to medium organizations, development/testing

Architecture:

┌─────────────────────────────────┐
│     Single Server               │
│  ┌──────────┐  ┌──────────┐    │
│  │ Frontend │  │ Backend  │    │
│  └──────────┘  └──────────┘    │
│       │              │          │
│       └──────┬───────┘          │
│              │                  │
│         ┌────▼────┐             │
│         │Database │             │
│         └─────────┘             │
└─────────────────────────────────┘

Pros: - Simple setup - Low resource requirements - Easy maintenance

Cons: - Single point of failure - Limited scalability - No redundancy

High Availability Deployment

Use Case: Production environments requiring uptime

Architecture:

Scaling Strategies

Horizontal Scaling

Frontend Scaling: - Deploy multiple frontend instances - Use load balancer for distribution - Stateless design allows easy scaling

Backend Scaling: - Deploy multiple backend instances - Use load balancer with session affinity (if needed) - Ensure database connection pooling

Vertical Scaling

Increase server resources (CPU, RAM)
Upgrade database server
Optimize application performance

Database Scaling

Read Replicas: For read-heavy workloads
Connection Pooling: Optimize database connections
Query Optimization: Improve query performance
Caching: Implement Redis for caching

Monitoring & Logging

Application Monitoring

Health Endpoints:
/api/system/status - System health
/api/system/metrics - Performance metrics
Logging:
Application logs
Access logs
Error logs
Audit logs
Metrics:
Response times
Error rates
Resource usage
Database performance

Monitoring Tools

Prometheus + Grafana: Metrics and visualization
ELK Stack: Log aggregation and analysis
Sentry: Error tracking
Uptime Monitoring: External monitoring services

Backup & Recovery

Backup Strategy

Database Backups:
Daily full backups
Hourly incremental backups
Off-site backup storage
Configuration Backups:
Export system configuration
Backup SSL certificates
Document custom settings
Application Backups:
Container images
Configuration files
Custom integrations

Recovery Procedures

Database Recovery:
Restore from backup
Verify data integrity
Test application functionality
Full System Recovery:
Restore infrastructure
Deploy application
Restore database
Verify functionality

Security Considerations

Network Security:
Firewall rules
VPN access
DDoS protection
Application Security:
SSL/TLS encryption
Security headers
Rate limiting
Input validation
Access Control:
Strong authentication
Role-based access
Audit logging
Regular security audits

Performance Optimization

Caching:
Redis for session storage
CDN for static assets
Application-level caching
Database Optimization:
Index optimization
Query optimization
Connection pooling
Application Optimization:
Code optimization
Resource optimization
Load balancing

Maintenance Windows

Schedule Maintenance:
Plan during low-usage periods
Notify users in advance
Prepare rollback plan
Update Procedures:
Test in staging first
Backup before updates
Deploy during maintenance window
Verify functionality
Monitor for issues
