ETL with Azure Cookbook

By: Christian Cote, Matija Lah, Madina Saitakhmetova

Overview of this book

ETL is one of the most common and tedious procedures for moving and processing data from one database to another. With the help of this book, you will be able to speed up the process by designing effective ETL solutions using the Azure services available for handling and transforming any data to suit your requirements. With this cookbook, you’ll become well versed in all the features of SQL Server Integration Services (SSIS) to perform data migration and ETL tasks that integrate with Azure. You’ll learn how to transform data in Azure and understand how legacy systems perform ETL on-premises using SSIS. Later chapters will get you up to speed with connecting and retrieving data from SQL Server 2019 Big Data Clusters, and even show you how to extend and customize the SSIS toolbox using custom-developed tasks and transforms. This ETL book also contains practical recipes for moving and transforming data with Azure services, such as Data Factory and Azure Databricks, and lets you explore various options for migrating SSIS packages to Azure. Toward the end, you’ll find out how to profile data in the cloud and automate service creation with Business Intelligence Markup Language (BIML). By the end of this book, you’ll have developed the skills you need to create and automate ETL solutions on-premises as well as in Azure.

Creating a SQL Server 2019 Big Data Cluster

SQL Server 2019 Big Data Clusters represents a new feature of the SQL Server platform, combining specific services and resources used in efficiently managing and analyzing very large sets of mostly non-relational data, and allowing it to be used alongside relational data hosted in SQL Server databases. To achieve these principal objectives, Big Data Clusters implement a highly scalable big-data storage (HDFS) system, highly versatile querying capabilities (Spark), the power of distributed computing (Kubernetes), and a data virtualization infrastructure (PolyBase).

To deploy all the required features that represent a single Big Data Clusters instance, you can use multiple physical—or virtual—machines that can either be hosted on premises or in the cloud.

As we do not want you to carry the burden of providing the necessary infrastructure to host the Big Data Cluster instance yourself, you are going to make use of the Azure...
