Training a model is rarely a single script; it is a chain of steps, fetch data, preprocess, train, evaluate, register, that must run reliably, repeatably, and often on cluster hardware nobody wants to babysit manually. Kubeflow Pipelines exists to turn that chain into a portable, containerised workflow that runs on Kubernetes, where each step is an isolated container and the whole graph is versioned, scheduled, and tracked. The problem it solves is the gap between a data scientist's laptop and production infrastructure: a notebook pipeline cannot scale, cannot be scheduled, and cannot reproduce its environment, while raw Kubernetes YAML is far too low-level for ML iteration. Kubeflow Pipelines provides a Python SDK that compiles a high-level pipeline definition into a Kubernetes-native workflow, giving each step its own dependencies, caching of unchanged steps, and a UI showing the DAG, logs, and artifacts. The payoff is that ML workflows become first-class, reproducible infrastructure that survive beyond the person who wrote them.

🏏 Think of it like cricket: imagine a batting coach analysing why Virat Kohli scored freely in one innings but struggled in another, yet kept no notes on which bat, which guard, or which net drills preceded each. Just as a detailed training diary logging bat weight, stance, and bowling type lets the coach link inputs to outputs, MLflow logs hyperparameters and data to outcomes. Just as comparing diary entries reveals that a heavier bat hurt timing, comparing tracked runs reveals which learning rate lifted accuracy. Just as a shared diary lets the whole support staff learn from one session, a shared tracking server lets the whole team learn from every run. The insight is that improvement is impossible without recorded cause and effect; tracking is what converts trial and error into knowledge.
