Production Deployment - Docker & Cloud

Welcome, @name! Darwin here with the final lesson of Module 6 - deploying FastAPI in production! 🚀☁️

Safari Analogy: Deployment is like opening a safari park to the public - we need to ensure security, scalability, and 24/7 reliability! 🦁🌐

Production checklist

• [ ] Environment variables (DATABASE_URL, SECRET_KEY)
• [ ] HTTPS/TLS certificates
• [ ] CORS configuration
• [ ] Rate limiting
• [ ] Logging & monitoring
• [ ] Database migrations (Alembic)
• [ ] Backup strategy
• [ ] Load balancer

Deploy to Render/Railway

Render:

1. Push to GitHub
2. Connect repo on Render
3. Add environment variables
4. Auto-deploy! ✅

Railway:

1. railway init
2. railway up
3. Done! ⚡

Module 6 Summary
