It’s important to know how to administer SQL Database to fully benefit from all of the features and functionality that it provides. This book addresses important aspects of an Azure SQL Database instance such as migration, backup restorations, pricing policies, security, scalability, monitoring, performance optimization, high availability, and disaster recovery. It is a complete guide for database administrators, and ideal for those who are planning to migrate from on premise SQL Server database to an Azure SQL Server database.

Chapter 6. Scaling Out Azure SQL Database

You can easily scale up or scale down an Azure SQL Database either automatically or manually. There are two types of scaling: vertical and horizontal.

Vertical scaling refers to switching to a higher or lower service tier, or vertically partitioning the data, which is to store different schema on different databases.

Horizontal scaling refers to dividing data from a single table into different individual databases.

This chapter teaches you how to auto scale Azure SQL Databases and shard a database. The chapter further talks about how to run cross-database queries.

By the end of this chapter, you will be able to:

  • Perform vertical and horizontal scaling
  • Run cross-database elastic queries
  • Create and maintain Azure SQL Database shards
