Overview of this book

Azure Synapse Analytics, which Microsoft describes as the next evolution of Azure SQL Data Warehouse, is a limitless analytics service that brings enterprise data warehousing and big data analytics together. With this book, you'll learn how to discover insights from your data effectively using this platform. The book starts with an overview of Azure Synapse Analytics, its architecture, and how it can be used to improve business intelligence and machine learning capabilities. Next, you'll go on to choose and set up the correct environment for your business problem. You'll also learn a variety of ways to ingest data from various sources and orchestrate the data using transformation techniques offered by Azure Synapse. Later, you'll explore how to handle both relational and non-relational data using the SQL language. As you progress, you'll perform real-time streaming and execute data analysis operations on your data using various languages, before going on to apply ML techniques to derive accurate and granular insights from data. Finally, you'll discover how to protect sensitive data in real time by using security and privacy features. By the end of this Azure book, you'll be able to build end-to-end analytics solutions while focusing on data prep, data management, data warehousing, and AI tasks.

Understanding information protection

Sometimes, just storing data securely is not sufficient. We need to protect data even when it is in motion and in use. Azure provides different security features to protect your data at any given time so that you can meet all the data-related compliances. These are as follows:

  • Encryption-in-flight (Transport Layer Security – TLS): The Synapse SQL pool secures your data by encrypting data in motion with TLS.
  • Encryption-at-rest (Transparent Data Encryption – TDE): TDE encrypts your databases, backups, and logs at rest. This setting is specific to one particular SQL pool. If you create another SQL pool in your Synapse workspace, then you need to enable this setting separately for that pool.

    The following screenshot shows how to enable data encryption for your Synapse SQL pools:
