Overview of this book

Microsoft SQL Server comes equipped with industry-leading features and the best online transaction processing capabilities. If you are looking to work with data processing and management, getting up to speed with Microsoft Server 2019 is key. Introducing SQL Server 2019 takes you through the latest features in SQL Server 2019 and their importance. You will learn to unlock faster querying speeds and understand how to leverage the new and improved security features to build robust data management solutions. Further chapters will assist you with integrating, managing, and analyzing all data, including relational, NoSQL, and unstructured big data using SQL Server 2019. Dedicated sections in the book will also demonstrate how you can use SQL Server 2019 to leverage data processing platforms, such as Apache Hadoop and Spark, and containerization technologies like Docker and Kubernetes to control your data and efficiently monitor it. By the end of this book, you'll be well versed with all the features of Microsoft SQL Server 2019 and understand how to use them confidently to build robust data management solutions.

SQL Server data files in Azure

This feature enables users to create SQL Server 2019 databases on premises, but the underlying data files (MDF, NDF, and LDF) are bound to Azure Blob storage rather than local storage:

Note

This hybrid technique is only recommended and supported for user databases and not system databases.

The separation of the compute layer (sqlservr.exe being on premises) and storage layer (Azure Storage) makes the recovery benefits seem more obvious. For example, if you lose the on-premises SQL Server instance, you can set up a new one without any manual data movement. Quite simply, all that is needed is to re-attach the datafiles. Once successfully set up, you can then leverage file-snapshot backups for database files in Azure (see the next section). This feature provides near-instantaneous backups and quick restores, making it a compelling solution for bigger databases.
