# MLOps

> MLOps is a set of practices that bring DevOps discipline to machine learning, automating the full model lifecycle — from data and training through deployment and production monitoring.

**MLOps** (Machine Learning Operations) is a set of practices, tools and processes that automate and standardise the entire lifecycle of machine learning models — from data ingestion, through training and validation, to production deployment and monitoring. MLOps brings the discipline familiar from [DevOps](https://nodea.io/en/glossary/devops) into the world of artificial intelligence, where alongside code you also version data and the trained models themselves.

## How MLOps works

A classic application pipeline operates on code alone. In machine learning, three variables drive the outcome: code, training data and the model artifact itself. MLOps binds them into a repeatable, auditable process:

- **Data and model versioning** — each model version is tied to a specific dataset and hyperparameters, making experiments reproducible and rollbacks possible.
- **Continuous training (CT)** — an extension of [CI/CD](https://nodea.io/en/glossary/ci-cd) that automatically retrains a model when new data arrives or prediction quality drops.
- **Model registry** — a central repository of approved model versions ready for deployment.
- **Monitoring and drift detection** — watching prediction quality and shifts in the input distribution (data drift) that quietly erode a model's accuracy.

## MLOps in practice

MLOps proves its worth anywhere a model reaches production and has to run reliably:

1. **Recommendation and scoring systems** — automatic retraining on fresh data keeps predictions accurate.
2. **Fraud detection** — fast rollback to a previous model version when a new one raises too many false positives.
3. **Containerised deployment** — models packaged into [Docker](https://nodea.io/en/glossary/docker) images and served as an API, unifying the training and production environments.

A solid infrastructure foundation — compute-capable servers, predictable networking and isolated environments — is a prerequisite for an MLOps pipeline to run repeatably and without surprises.

### How does MLOps differ from classic DevOps?

DevOps manages the lifecycle of code whose behaviour is deterministic. MLOps adds versioning of data and models plus continuous validation, because a model degrades over time as input data shifts. Beyond code tests, it needs prediction-quality checks and drift detection.
