What is MLOps?

MLOps exists because shipping a machine learning model is radically different from shipping traditional software. A conventional application does what its code says, always. An ML model does what its training data implied, probabilistically. Models degrade silently as the world changes, produce subtly wrong outputs that are hard to detect, and require retraining pipelines that are just as complex as the original training process. MLOps is the engineering discipline built to manage this complexity at scale.

An MLOps workflow typically covers several stages. Data pipelines ingest, clean, and version training data. Experiment tracking records hyperparameter choices, metrics, and model versions. CI/CD pipelines automate model training and evaluation when new data or code is available. Model deployment infrastructure serves models reliably under production load. Monitoring systems detect data drift, concept drift, and performance degradation over time, triggering alerts and retraining when necessary.

The tooling ecosystem for MLOps has matured rapidly. Platforms like MLflow, Weights & Biases, and Kubeflow address experiment tracking and pipeline orchestration. Feature stores standardize how features are computed and served. Model registries track versioning and approval workflows. Vector databases support RAG and embedding-based search at scale. Together, these tools form the operational backbone for teams running AI in production.

For organizations adopting AI, MLOps maturity is often the difference between a successful production deployment and a science project that never ships. Without MLOps practices, models get deployed once, degrade without detection, and create trust problems that are hard to recover from. Investing in MLOps infrastructure, even at small scale, is one of the highest-leverage actions an AI team can take to turn experiments into durable business value.
