Why MLflow?
Machine learning isn’t just about training models—it’s about managing the entire lifecycle, from experiment tracking and reproducibility to model deployment and monitoring. This is where MLflow comes in.
MLflow is an open-source platform designed to streamline ML workflows by providing:
- Experiment Tracking: Logging model parameters, metrics, and artifacts.
- Model Registry: Storing and managing different model versions.
- Model Deployment: Deploying models across multiple platforms.
- Reproducibility: Ensuring consistency across training runs.
AzureML integrates some MLflow functionalities but also provides its own alternative tools for model lifecycle management. Let’s compare them.

📌 Key Takeaway: While MLflow is flexible and works across platforms, AzureML offers deeper integration with the Azure ecosystem, making it ideal for production workloads.
Using MLflow in AzureML
AzureML natively supports MLflow, meaning you can log experiments, register models, and track metrics directly inside an AzureML workspace.
Enabling MLflow in AzureML
Integrating MLflow with AzureML provides seamless tracking, logging, and model versioning capabilities. By setting up MLflow within an AzureML workspace, users can leverage the best of both tools to improve model development and deployment efficiency. This allows data scientists to track experiments across different runs, compare model performances, and ensure consistency in results. Additionally, integrating MLflow with AzureML ensures that models trained locally can be easily transitioned to Azure's scalable infrastructure. First, install MLflow and the AzureML SDK:
pip install mlflow azureml-mlflow
Then, enable MLflow inside an AzureML workspace:

📌 What’s happening? This connects MLflow to AzureML’s backend, allowing you to log experiments within Azure.
Experiment Tracking with MLflow in AzureML
When training models, logging experiments helps compare different runs and evaluate performance over time.
Logging an Experiment
Experiment tracking is crucial in machine learning, as it allows developers to store and compare various configurations, hyperparameters, and results. With MLflow, tracking experiments becomes effortless, ensuring that each training run is properly documented. This is especially useful when iterating over different models or hyperparameter tuning strategies. By systematically logging experiments, teams can enhance collaboration and maintain a clear record of past performance trends. Additionally, MLflow’s integration with AzureML enables model lineage tracking, which simplifies compliance and reproducibility.

📌 Key Insight: MLflow automatically tracks parameters and metrics, making it easier to monitor training progress.
Registering and Deploying a Model in AzureML
Once a model is trained, it needs to be registered and deployed for production use.
Registering the Model
Once a model is trained and evaluated, registering it within AzureML ensures that it is stored, versioned, and ready for deployment. Model registration is a critical step in the ML lifecycle, as it allows different teams to access and reuse models without confusion. AzureML provides an intuitive interface to manage model versions, making it easier to roll back to previous iterations if needed. Additionally, registered models can be tagged with metadata, helping in categorization and searchability.
