FAQ
-
Azure SQL Database is available as a single database with its own set of resources managed via a logical server, and as a pooled database in an elastic pool, with a shared set of resources managed through a logical server. In general, elastic pools are designed for a typical software-as-a-service (SaaS) application pattern, with one database per customer or tenant. With pools, you manage the collective performance, and the databases scale up or down automatically.

Azure Hybrid Benefit helps you maximize the value of your current licensing investments and accelerate your migration to the cloud. Azure Hybrid Benefit for SQL Server is an Azure-based benefit that enables you to use your SQL Server licenses with active Microsoft Software Assurance to pay a reduced rate ("base rate") on vCore-based Azure SQL services. Further optimize your costs with centralized management of your Azure Hybrid Benefit across your entire subscription or billing account.

No. Azure SQL Database is a fully managed database service—Microsoft operates SQL Server for you and ensures its availability and performance. SQL Database also includes features to enhance your business continuity and security, such as built-in high availability and threat detection, so that you don't have to worry about administering or maintaining your SQL Server databases.

The vCore-based service tiers are primarily differentiated by availability, storage type, and input/output (I/O) per second. General purpose is a budget-oriented option that's best when input/output performance or failover time is not the priority. Hyperscale is optimized for online transaction processing (OLTP) and hybrid transactional analytical workloads. The business critical tier is best for OLTP applications with high transaction rates and low I/O latency requirements.

Connectivity between Azure SQL Database and the Azure internet gateway is guaranteed at least 99.995 percent of the time for zone-redundant deployments, regardless of your service tier. For more information, read the SLA and learn about the high-availability architecture.

SQL databases, also known as relational databases, are systems that store collections of tables and organize structured sets of data in a tabular columns-and-rows format, similar to that of a spreadsheet.

- [1] Price-performance claims based on data from a study commissioned by Microsoft and conducted by Principled Technologies in December 2023. The study compared performance and price performance between a 16 vCore and 32 vCore Azure SQL Database using premium-series hardware on the Hyperscale service tier and the db.r6i.4xlarge and db.r6i.8xlarge offerings for Amazon Aurora PostgreSQL I/O-Optimized (“Amazon Aurora”). Benchmark data is taken from a Principled Technologies report which used the HammerDB TPROC-C benchmark. The TPROC-C workload is derived from the TPC-C Benchmark and results were obtained with the HammerDB TPROC-C workload. The HammerDB TPROC-C workload is derived from the TPC-C benchmark and is not comparable to published TPC-C Benchmark results, as this implementation does not comply with all requirements of the TPC Benchmark. Price-performance is calculated by Principled Technologies as the cost of running the cloud platform continuously divided by new orders per minute throughput, based upon the standard. Prices are based on publicly available US pricing in East US 1 for Azure SQL Database and US East for Amazon Aurora as of December 2023. Performance and price-performance results are based upon the configurations detailed in the Principled Technologies report. Actual results and prices may vary based on configuration and region.
