You have an application named Appl that connects to a Microsoft Azure SQL database named AppDBl. Appl uses columnstore indexes as part of the database schema. You plan to deploy another Azure SQL…

The Basic service tier does not support columnstore indexes, which makes it incompatible with the application's schema requirements.

The Standard service tier supports columnstore indexes, which is a required feature for the application. It offers a balance of performance and cost, and crucially, it is the lowest-cost tier that provides columnstore index support, aligning with the requirement to minimize cost for a development environment.

The Premium service tier supports columnstore indexes but provides higher performance and significantly higher cost, which is unnecessary when the primary goal is cost minimization for a development database.

Premium RS (Read Replica) is a variant of the Premium tier, offering read scale-out capabilities and supporting columnstore indexes. However, it incurs higher costs than the Standard tier and is overkill for a development environment focused on cost minimization.
