Pipeline Green, Production Red: The Hidden Cost of CI/CD Blindness

A common trap in continuous integration is the false confidence that green pipeline checks provide. This article reveals why CI/CD systems often miss real-world production failures—from environmental drift and unpredictable data to traffic load differences—and demonstrates how Docker layer caching can bridge the gap while dramatically reducing deployment times. Understanding these systematic gaps is critical for preventing costly production incidents and building truly reliable delivery pipelines.
