Overview of this book

Large volumes of data are generated daily from applications, websites, IoT devices, and other free-text, semi-structured data sources. Azure Synapse Data Explorer helps you collect, store, and analyze such data, and work with other analytical engines, such as Apache Spark, to develop advanced data science projects and maximize the value you extract from data. This book offers a comprehensive view of Azure Synapse Data Explorer, exploring not only the core scenarios of Data Explorer but also how it integrates within Azure Synapse. From data ingestion to data visualization and advanced analytics, you’ll learn to take an end-to-end approach to maximize the value of unstructured data and drive powerful insights using data science capabilities. With real-world usage scenarios, you’ll discover how to identify key projects where Azure Synapse Data Explorer can help you achieve your business goals. Throughout the chapters, you'll also find out how to manage big data as part of a software as a service (SaaS) platform, as well as tune, secure, and serve data to end users. By the end of this book, you’ll have mastered the big data life cycle and you'll be able to implement advanced analytical scenarios from raw telemetry and log data.

Managing data encryption

For Azure Synapse workspaces, all data is stored with at least one layer of encryption, ensuring that data is never persisted on disk in its original, clear form. You don’t have the option to not encrypt data at rest. This applies to any of the analytical engines in Azure Synapse as well as to data persisted, even temporarily, by integration pipelines.

In addition to this first layer of encryption, Azure Synapse workspaces offer an optional, additional layer of encryption, named double encryption. This feature helps protect data and keeps it encrypted even if one of the encryption layers gets compromised. Double encryption uses a customer-managed key, which is stored in Azure Key Vault, giving you full responsibility for key management. The first layer of encryption, on the other hand, uses platform-managed keys, which you don’t have access to. Both layers use 256-bit Advanced Encryption Standard encryption, known simply as AES 256.
