Which options are available when selecting Azure SQL Database?

Choosing Azure SQL Database provides two primary deployment models: Single Database and Elastic Pool.

Single Database is a standalone database that can be scaled and managed independently. It offers full capabilities of a traditional database and is ideal for applications that require a specifically tailored database solution, with dedicated resources for a single database workload.

On the other hand, Elastic Pool is designed to manage multiple databases that have variable usage patterns. This option allows databases to draw from a shared set of resources, which can lead to cost savings and better performance management for applications that experience fluctuating workloads. For instance, if one database is inactive while another peaks, both can share the same resources without the risk of performance bottlenecks.

These two options are specifically tailored to meet different usage scenarios and resource management needs, making them valid and essential choices within Azure SQL Database offerings.

The other choices listed contain either combinations not supported within the Azure SQL Database service or terminologies that do not accurately represent the available options. Therefore, focusing on the functionalities offered by Single Database and Elastic Pool provides the most accurate representation of Azure SQL Database options.
