Previously, when applying deployment pipelines to my projects, I didn't fully understand the concepts and relied on AI just to make them "work." As a result, it was difficult to apply those methods to other projects, and I faced limitations in identifying the root causes when problems occurred. Through this lecture, I was able to understand the big picture of how CI/CD pipelines actually operate organically, from Infrastructure as Code (IaC) to cloud deployment. It was very helpful to be able to organize concepts that I previously only knew in fragments into a single, cohesive flow. I highly recommend this lecture to anyone who has experience with deployment pipelines but wants to properly grasp the underlying concepts and principles!
