By: Ahmad Osama

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.

Choosing Between a vCore Pricing Model and DTU-based Service Tiers

When choosing between vCore and DTU-based pricing tiers, consider the following.

Licensing

A vCore pricing model provides up to 30% cost savings by using existing on-premises SQL Server Standard or Enterprise licenses with software assurance. Therefore, if you are migrating an existing on-premises SQL Server infrastructure, consider opting for a vCore pricing model.

Flexibility

A DTU-based model bundles up the compute, IOPs, and storage under DTUs and provides a pre-configured range of varying DTU amounts for different types of workloads. It's therefore best suited for when you need a simple pre-configured option.

A vCore model provides flexibility when selecting compute and storage options and is therefore best when you want more transparency with control and over the compute and storage options.

Consider a scenario where you have a database with high compute requirements and low storage requirements; say, 125 DTUs with...
