Distributed Data Systems with Azure Databricks

By: Alan Bernardo Palacio

Overview of this book

Microsoft Azure Databricks helps you to harness the power of distributed computing and apply it to create robust data pipelines, along with training and deploying machine learning and deep learning models. Databricks' advanced features enable developers to process, transform, and explore data. Distributed Data Systems with Azure Databricks will help you to put your knowledge of Databricks to work to create big data pipelines. The book provides a hands-on approach to implementing Azure Databricks and its associated methodologies that will make you productive in no time. Complete with detailed explanations of essential concepts, practical examples, and self-assessment questions, you’ll begin with a quick introduction to Databricks core functionalities, before performing distributed model training and inference using TensorFlow and Spark MLlib. As you advance, you’ll explore MLflow Model Serving on Azure Databricks and implement distributed training pipelines using HorovodRunner in Databricks. Finally, you’ll discover how to transform, use, and obtain insights from massive amounts of data to train predictive models and create entire fully working data pipelines. By the end of this MS Azure book, you’ll have gained a solid understanding of how to work with Databricks to create and manage an entire big data pipeline.

Working with VNets in Azure Databricks

Azure Databricks can be deployed within a custom virtual network. This is called VNet injection and is very important from a security perspective. When we deploy with default settings, inbound traffic is closed, but outbound traffic is open without restrictions. When we use VNet injection and we deploy directly to a custom virtual network, we can apply the same security policies around all our Azure Services, to meet compliance and security requirements.  

In case you are working in data science or exploratory environments, it's good to leave the outbound traffic open to be able to download packages and libraries for Python, R, and Maven, and Ubuntu packages also.

As we have mentioned before, Azure Databricks works on two planes of service. The first is the control page, which we use through the Databricks API to work with workspace assets. The second is the data plane where the clusters are deployed. It is this second plane...
