Infrastructure Architecture

Port Configuration and Management

• Default Port: 5000
• Configurable via Environment Variable: PORT
• Dynamic Port Allocation
  • Automatic port finding if default port is occupied
  • Ensures flexibility across different deployment environments

Port Configuration Strategies

1. Static Port Assignment

   • Predefined port (default: 5000)
   • Consistent across environments

2. Dynamic Port Allocation

   • Automatic port discovery
   • Prevents port conflicts
   • Enhances deployment flexibility

3. Environment-Specific Configuration

   • Development: Typically localhost
   • Staging: Configurable ports
   • Production: Reverse proxy configuration
