MLOps (machine learning operations) applies DevOps practices such as version control, automated testing and continuous delivery to machine learning, and adds what models specifically need: data and model versioning, experiment tracking, monitoring for data drift and regular retraining. DevOps keeps software running; MLOps keeps models accurate as the world they learned from changes.
| Area | DevOps | MLOps |
|---|---|---|
| What is versioned | Source code and configuration | Code, training data, features and model artefacts |
| Testing | Unit, integration and performance tests | Also data validation, model accuracy and bias checks |
| Releases | Triggered by code changes | Triggered by code changes, new data or falling accuracy |
| Monitoring | Uptime, errors, latency | Also data drift, prediction quality and cost per prediction |
| Typical failure | Crash or error | Silent decline in accuracy |
A web application behaves the same way until someone changes its code. A model’s behaviour depends on the data it was trained on. When customer behaviour, prices, suppliers or language change, the data moves away from what the model learned, a problem known as data drift. The application still runs and returns answers, but the answers get worse. Without MLOps, teams often discover this months later through business results rather than alerts.
Reproducibility is the second gap. To audit or fix a model, you need to know exactly which data, code and settings produced it. Ordinary source control does not capture datasets or trained model files.
Applications built on large language models need the same discipline, sometimes called LLMOps: versioning prompts and model choices, evaluation sets of real questions with expected answers, monitoring of answer quality and safety, and close tracking of token costs. A prompt change is a release and should be tested like one.
We implement MLOps on Azure Machine Learning, AWS SageMaker and Databricks. See our MLOps and model lifecycle management service and DevOps services, or hire ML developers and DevOps engineers.

DevOps manages code releases and infrastructure. MLOps adds the management of data, trained models, accuracy monitoring and retraining, because models can degrade even when the code does not change.
Data drift happens when the data a model sees in production differs from the data it was trained on, for example because customer behaviour changes. It causes accuracy to fall gradually.
Common tools include MLflow for tracking and registry, Azure Machine Learning, AWS SageMaker or Databricks for training and deployment, and GitHub Actions or Azure DevOps for CI/CD.
Yes, at a lighter level. Even one production model needs versioning, monitoring and a safe way to retrain. The tooling can be kept simple.
