Day 40: Continuous Deployment - From Code to Production in Minutes
What We’re Building Today
Today we’re extending yesterday’s CI pipeline to automatically deploy our Quiz Platform backend services to production. We’ll create a bulletproof CD pipeline that takes tested code and safely deploys it across multiple environments.
Learning Agenda:
Multi-environment deployment strategy (staging → production)
Blue-green deployment implementation
Automated rollback mechanisms
Health checks and monitoring integration
Database migration handling
Why CD Pipelines Matter in Real Systems
Netflix deploys code to production thousands of times per day. Facebook pushes updates every few minutes. This isn’t reckless - it’s strategic. Smaller, frequent deployments reduce risk and enable rapid feature delivery.
Your Quiz Platform needs this same capability. When students are taking exams, you can’t afford 2-hour maintenance windows. CD pipelines enable zero-downtime deployments while maintaining system reliability.
