Understanding why deployment matters is one of the most essential skills for every software engineer — whether you’re a beginner or already building real products. In this 15-minute lecture, we break down the true purpose of deployment, how environments work, and why your application behaves differently in local vs. cloud environments.

You’ll learn why running code on your laptop isn’t enough, and why every real-world product needs proper environments like Dev, Stage, and Production.
