What is Azure Machine Learning?
In this article, you learn about Azure Machine Learning, a cloud-based environment you can use to train, deploy, automate, manage, and track ML models.
Azure Machine Learning can be used for any kind of machine learning, from classical ml to deep learning, supervised, and unsupervised learning. Whether you prefer to write Python or R code or zero-code/low-code options such as the designer, you can build, train, and track highly accurate machine learning and deep-learning models in an Azure Machine Learning Workspace.
Start training on your local machine and then scale out to the cloud.
The service also interoperates with popular deep learning and reinforcement open-source tools such as PyTorch, TensorFlow, scikit-learn, and Ray RLlib.

What is machine learning?
Machine learning is a data science technique that allows computers to use existing data to forecast future behaviors, outcomes, and trends. By using machine learning, computers learn without being explicitly programmed.
Forecasts or predictions from machine learning can make apps and devices smarter. For example, when you shop online, machine learning helps recommend other products you might want based on what you've bought. Or when your credit card is swiped, machine learning compares the transaction to a database of transactions and helps detect fraud. And when your robot vacuum cleaner vacuums a room, machine learning helps it decide whether the job is done.
Machine learning tools to fit each task
Azure Machine Learning provides all the tools developers and data scientists need for their machine learning workflows, including:
The Azure Machine Learning designer (preview): drag-n-drop modules to build your experiments and then deploy pipelines.
R scripts or notebooks in which you use the SDK for R to write your own code, or use the R modules in the designer.
- The Many Models Solution Accelerator (preview) builds on Azure Machine Learning and enables you to train, operate, and manage hundreds or even thousands of machine learning models.
Open-source frameworks such as PyTorch, TensorFlow, and scikit-learn and many more
Reinforcement learning with Ray RLlib
Build ML models in Python or R
With many available compute targets, like Azure Machine Learning Compute and Azure Databricks, and with advanced hyperparameter tuning services, you can build better models faster by using the power of the cloud.
You can also automate model training and tuning using the SDK.
Build ML models with no-code tools
For code-free or low-code training and deployment, try:
Azure Machine Learning designer (preview)
Use the designer to prep data, train, test, deploy, manage, and track machine learning models without writing any code. There is no programming required, you visually connect datasets and modules to construct your model. Try out the designer tutorial.

MLOps: Deploy & lifecycle management
When you have the right model, you can easily use it in a web service, on an IoT device, or from Power BI. For more information, see the article on how to deploy and where.
And with advanced machine learning pipelines, you can collaborate on each step from data preparation, model training and evaluation, through deployment. Pipelines allow you to:
- Automate the end-to-end machine learning process in the cloud
- Reuse components and only rerun steps when needed
- Use different compute resources in each step
- Run batch scoring tasks
If you want to use scripts to automate your machine learning workflow, the machine learning CLI provides command-line tools that perform common tasks, such as submitting a training run or deploying a model.

Your Azure Storage account, compute targets, and other resources can be used securely inside a virtual network to train models and perform inference. For more information, see Secure experimentation and inference in a virtual network.
Basic & Enterprise editions
Azure Machine Learning offers two editions tailored for your machine learning needs:
Basic: Great for open-source development at cloud scale with a code-first experience.
Enterprise: All of Basic plus a web interface (studio) + secure, comprehensive ML lifecycle management for all skill levels.
To learn more about these editions and what capabilities they unlock, read the "Azure Machine Learning Editions" article.
