Overview of this book

Despite being the cloud version of SQL Server, Azure SQL Database differs in key ways when it comes to management, maintenance, and administration. This book shows you how to administer Azure SQL Database to fully benefit from its wide range of features and functionalities. Professional Azure SQL Database Administration begins by covering the architecture and explaining the difference between Azure SQL Database and the on-premise SQL Server to help you get comfortable with Azure SQL Database. You’ll perform common tasks such as migrating, backing up and restoring a SQL Server database to an Azure database. As you progress, you’ll understand how you can reduce costs, and manage and scale multiple SQL databases using elastic pools. You’ll also implement a disaster recovery solution using standard and active geo-replication. Whether it is learning different techniques to monitor and tune an Azure SQL Database or improving performance using in-memory technology, this book will enable you to make the most out of Azure SQL database features and functionality for data management solutions. By the end of this book, you’ll be well-versed with key aspects of an Azure SQL Database instance, such as migration, backup restorations, performance optimization, high availability, and disaster recovery.

Introduction

There are very few relational database systems as established and widely used as Microsoft's SQL Server. Azure SQL Database, released on February 1, 2010, is a cloud database service that is based on Microsoft's SQL Server.

It is compatible with most SQL Server features and is optimized for Software-as-a-Service (SaaS) applications.

As organizations are adopting cloud computing and moving their applications into the cloud, Azure SQL Database offers everything that Database-as-a-Service (DBaaS) can offer. Azure SQL Database is a DBaaS option for any organization with applications built on SQL Server Database.

Azure SQL Database uses familiar Transact-SQL programming and a user interface that is well known and is also easy to adopt. It is therefore important for SQL Server Database administrators and developers to learn how to use Azure SQL Database.

Note

Azure SQL Database is also known as SQL Azure or SQL Database instance.

This lesson covers the Azure SQL Database architecture in detail. After familiarizing ourselves with the architecture, we'll learn how to provision Azure SQL Database through activities and explore pricing, settings, and its properties. We'll also identify the key differences between Azure SQL Database and SQL Server – mainly the SQL Server features that are not supported by Azure SQL Database.
