 The **Microsoft Data Science Virtual Machine (DSVM)** is also available as an Azure virtual machine (VM) image. This VM is pre-installed and configured with several popular tools that are commonly used for data analytics and machine learning. The DSVM is available on both Windows and Linux. For more information, see [Introduction to the cloud-based Data Science Virtual Machine for Linux and Windows](../data-science-virtual-machine/overview.md).
