    What is Azure SQL Database?

    Article 09/19/2022 19 minutes to read

    Applies to: Azure SQL Database

    Azure SQL Database is a fully managed platform as a service (PaaS) database engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement. Azure SQL Database is always running on the latest stable version of the SQL Server database engine and patched OS with 99.99% availability. PaaS capabilities built into Azure SQL Database enable you to focus on the domain-specific database administration and optimization activities that are critical for your business.

    With Azure SQL Database, you can create a highly available and high-performance data storage layer for the applications and solutions in Azure. SQL Database can be the right choice for a variety of modern cloud applications because it enables you to process both relational data and non-relational structures, such as graphs, JSON, spatial, and XML.

    Azure SQL Database is based on the latest stable version of the Microsoft SQL Server database engine. You can use advanced query processing features, such as high-performance in-memory technologies and intelligent query processing. In fact, the newest capabilities of SQL Server are released first to SQL Database, and then to SQL Server itself. You get the newest SQL Server capabilities with no overhead for patching or upgrading, tested across millions of databases.

    SQL Database enables you to easily define and scale performance within two different purchasing models: a vCore-based purchasing model and a DTU-based purchasing model. SQL Database is a fully managed service that has built-in high availability, backups, and other common maintenance operations. Microsoft handles all patching and updating of the SQL and operating system code. You don't have to manage the underlying infrastructure.

    If you're new to Azure SQL Database, check out the Azure SQL Database Overview video from our in-depth Azure SQL video series:

    Deployment models

    Azure SQL Database provides the following deployment options for a database:

    Single database represents a fully managed, isolated database. You might use this option if you have modern cloud applications and microservices that need a single reliable data source. A single database is similar to a contained database in the SQL Server database engine.

    Elastic pool is a collection of single databases with a shared set of resources, such as CPU or memory. Single databases can be moved into and out of an elastic pool.

    Important

    To understand the feature differences between SQL Database, SQL Server, and Azure SQL Managed Instance, as well as the differences among different Azure SQL Database options, see SQL Database features.

    SQL Database delivers predictable performance with multiple resource types, service tiers, and compute sizes. It provides dynamic scalability with no downtime, built-in intelligent optimization, global scalability and availability, and advanced security options. These capabilities allow you to focus on rapid app development and accelerating your time-to-market, rather than on managing virtual machines and infrastructure. SQL Database is currently in 38 datacenters around the world, so you can run your database in a datacenter near you.

    Scalable performance and pools

    You can define the amount of resources assigned.

    With single databases, each database is isolated from others and is portable. Each has its own guaranteed amount of compute, memory, and storage resources. The amount of the resources assigned to the database is dedicated to that database, and isn't shared with other databases in Azure. You can dynamically scale single database resources up and down. The single database option provides different compute, memory, and storage resources for different needs. For example, you can get 1 to 128 vCores, or 32 GB to 4 TB. The Hyperscale service tier for single databases enables you to scale to 100 TB, with fast backup and restore capabilities.

    With elastic pools, you can assign resources that are shared by all databases in the pool. You can create a new database, or move the existing single databases into a resource pool to maximize the use of resources and save money. This option also gives you the ability to dynamically scale elastic pool resources up and down.

    You can build your first app on a small, single database at a low cost per month in the General Purpose service tier. You can then change its service tier manually or programmatically at any time to the Business Critical or Hyperscale service tier, to meet the needs of your solution. You can adjust performance without downtime to your app or to your customers. Dynamic scalability enables your database to transparently respond to rapidly changing resource requirements. You pay for only the resources that you need when you need them.
