Azure SQL Database

Azure fully managed PaaS relational database engine based on the latest stable SQL Server.

Definition

Azure SQL Database offers single databases and elastic pools under the DTU or vCore purchasing models, with General Purpose, Business Critical and Hyperscale service tiers and a serverless compute tier. It provides automated backups, point-in-time restore, active geo-replication, failover groups and built-in high availability.

Example

A SaaS vendor places 200 small tenant databases in an elastic pool to share resources cost-effectively.

Exam tip

Elastic pools fit many databases with variable, unpredictable usage; SQL Managed Instance fits lift-and-shift needing instance-level features.
