Introduction: From POC to Production
Your model works in Jupyter. It even works in staging. But production is a different beast: millions of users, malicious actors, unexpected edge cases, and zero tolerance for downtime.
Production ML requires thinking beyond accuracy: security, reliability, scalability, cost, and maintainability all matter.
Key Insight: Building production ML systems is 10% ML and 90% software engineering, infrastructure, and operational excellence.
Learning Objectives
- Implement security best practices
- Design for reliability and fault tolerance
- Build scalable serving infrastructure
- Optimize costs
- Handle edge cases and errors gracefully
- Establish incident response procedures
- Create comprehensive documentation
1. Security Best Practices
Input Validation
Never trust user input! Validate everything:
Rate Limiting
2. Error Handling and Graceful Degradation
3. Monitoring and Alerting
4. Cost Optimization
5. Incident Response Playbook
Key Takeaways
✅ Security first: Validate inputs, rate limit, protect against attacks
✅ Reliability: Implement fallbacks, handle errors gracefully
✅ Monitoring: Track metrics, set alerts, investigate anomalies
✅ Cost optimization: Choose right infrastructure, scale appropriately
✅ Incident response: Have playbooks ready, practice regularly
✅ Documentation: Document everything – architecture, decisions, procedures
