![]() To gain deeper insight into the resource (DTU) consumption of your workload, use query-performance insights to: A premium service tier P11 database with 1750 DTUs provides 350 times more DTU compute power than a basic service tier database with 5 DTUs.Doubling the DTUs by increasing the compute size of a database equates to doubling the set of resources available to that database.Likewise, the resources used by other workloads don't impact the resources available to your database.ĭTUs are most useful for understanding the relative resources that are allocated for databases at different compute sizes and service tiers. When your workload exceeds the amount of any of these resources, your throughput is throttled, resulting in slower performance and time-outs.įor single databases, the resources used by your workload don't impact the resources available to other databases in the Azure cloud. The ratio among these resources is originally determined by an online transaction processing (OLTP) benchmark workload designed to be typical of real-world OLTP workloads. The amount of resources allocated for a database is calculated as a number of DTUs and is a bundled measure of compute, storage, and I/O resources. This guarantee provides a predictable level of performance. ![]() Single databases and elastic pools are billed hourly based on service tier and compute size.įor a single database at a specific compute size within a service tier, Azure SQL Database guarantees a certain level of resources for that database (independent of any other database). All service tiers in the DTU-based purchasing model provide flexibility of changing compute sizes with minimal downtime however, there is a switch over period where connectivity is lost to the database for a short amount of time, which can be mitigated using retry logic. ![]() Service tiers in the DTU-based purchasing model are differentiated by a range of compute sizes with a fixed amount of included storage, fixed retention period for backups, and fixed price. Database transaction units (DTUs)Ī database transaction unit (DTU) represents a blended measure of CPU, memory, reads, and writes. To learn more, review vCore-based purchasing model and compare purchasing models. In this article, learn about the DTU-based purchasing model for Azure SQL Database.
