🚀 Quick Start

Option 1: Hugging Face Spaces (Recommended)

1. Fork this Space:

   git clone https://huggingface.co/spaces/your-username/qwen-production
   cd qwen-production
   

2. Enable GPU (Optional but recommended):

   • Go to Space settings
   • Enable "T4 Medium" GPU
   • Upgrade to persistent storage

3. Deploy:

   • Push changes to trigger rebuild
   • Access via Spaces URL

Option 2: Modal Deployment

1. Install Modal:

   pip install modal
   modal token new
   

2. Create Modal App:

   # modal_deploy.py
   import modal
   
   app = modal.App("qwen-production")
   
   image = modal.Image.debian_slim().pip_install([
       "torch", "transformers", "gradio", "accelerate"
   ])
   
   @app.function(image=image, gpu="T4", timeout=300)
   def inference(prompt: str) -> str:
       # Your deployment code here
       pass
   

3. Deploy:

   modal deploy modal_deploy.py
   

Option 3: Docker Deployment

1. Build Image:

   docker build -t qwen-production .
   

2. Run Container:

   docker run -p 7860:7860 \
     -v $(pwd)/data:/app/data \
     -e HUGGING_FACE_HUB_TOKEN=your_token \
     qwen-production
   

3. Access:

   http://localhost:7860

📈 Scaling Considerations

Horizontal Scaling

• Load balancers for multiple instances
• Session affinity for conversation memory
• Shared database for metrics aggregation

Vertical Scaling

• GPU upgrades for higher throughput
• Memory increases for longer contexts
• CPU optimization for better performance

Auto-scaling Triggers

• Request queue length > 10
• Average response time > 5s
• Error rate > 5%
• CPU/Memory utilization > 80%

🔒 Security Best Practices

1. Authentication: API keys, OAuth integration
2. Rate Limiting: Per-user request limits
3. Content Security: CSP headers, XSS protection
4. Data Privacy: Conversation encryption, PII handling
5. Audit Logging: Comprehensive request logging
