Production Deployment

Guidelines for deploying Orb in production environments.

Architecture

Recommended Setup

Internet
   ↓
Load Balancer (TLS termination)
   ↓
Reverse Proxy (Nginx/Caddy)
   ↓
Orb Relay Servers (multiple instances)
   ↓
Session Database (Redis/PostgreSQL)

TLS Configuration

Generate Certificates

# Let's Encrypt
sudo certbot certonly --standalone -d relay.example.com

# Self-signed (development only)
openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365

Configure TLS Relay

Use reverse proxy (Nginx/Caddy) for TLS termination.

High Availability

Load Balancing

upstream orb_relays {
    least_conn;
    server relay1.internal:8080;
    server relay2.internal:8080;
    server relay3.internal:8080;
}

Session Persistence

Implement sticky sessions or shared session store.

Monitoring and Logging

Prometheus Metrics

• Connection count
• Active sessions
• Bandwidth usage
• Error rates

Logging

# Structured logging
orb relay 2>&1 | tee -a /var/log/orb/relay.log

Backup and Recovery

• Configuration backup
• Log retention
• Disaster recovery plan

Security Hardening

• Minimal permissions
• SELinux/AppArmor
• Firewall rules
• DDoS protection
• Rate limiting
• Regular audits

Scaling

Horizontal Scaling

Add more relay servers behind load balancer.

Vertical Scaling

Increase CPU/RAM for existing servers.

Next Steps

• Relay Server Setup
• Docker Deployment
