Overview of this book

As the cloud version of SQL Server, Azure SQL Database differs in key ways when it comes to management, maintenance, and administration. 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.

Vertical Scaling

Vertical scaling can be of two types: scale up or scale down service tiers, and vertical partitions.

Scale Up or Scale Down Service Tiers

Scaling up a service tier refers to switching to a higher service tier, for example, switching from Basic to Standard S0 or switching from Standard S0 to Standard S1.

Scaling down a service tier refers to switching to a lower service tier, for example, switching from Standard S1 to Standard S0, or switching from Standard S0 to Basic.

Scaling up a service tier allows you to maintain or improve database performance in peak business hours, and scaling down a service tier allows you to save costs during off-peak business hours.

The service tier is changed on the fly with zero downtime. When a service tier change request is sent to the Azure SQL Database, it first creates a copy of the database in the requested service tier and switches to the database in the new service tier once the copy is ready.

You are charged for the new service tier...
