Microsoft Azure SQL Database (formerly known as SQL Azure, SQL Server Data Services, SQL Services, and Windows Azure SQL Database) is a managed cloud database (PaaS) cloud-based Microsoft SQL Servers, provided as part of Microsoft Azure services. The service handles database management functions for cloud based Microsoft SQL Servers including upgrading, patching, backups, and monitoring without user involvement.

Overview

Azure SQL Database supports multi-modal storage of structured, semi-structured, and non-relational data.

Azure SQL Database includes built-in intelligence that learns app patterns and adapts them to maximize performance, reliability, and data protection.

Key capabilities include:

Learning of the host app's data access patterns, adaptive performance tuning, and automatic improvements to reliability and data protection.
Scaling on demand.
Management and monitoring of multi-tenant apps with isolation benefits of one-customer-per-database.
Integration with open-source tools such as cheetah (Command-line interface utility), sql-cli, Visual Studio Code, and Microsoft tools like Visual Studio, SQL Server Management Studio, Azure Management Portal, PowerShell, and REST APIs.
Data protection with encryption, authentication, limiting user access to the subset of the data, continuous monitoring and auditing to help detect potential threats and provide a record of critical events in case of a breach.

Popular use cases

Relational data storage for cloud-based applications and websites
Business and consumer web and mobile apps
Manage databases for multi-tenant apps (software-as-a-service)
Quickly create dev and test databases to speed up development cycles
Scale production business services quickly and at a known cost
Containerize data in the cloud for isolation and security
Reduce database administration overhead through increased automation

Design

Azure SQL Database is built on the foundation of the SQL server database and therefore, kept in sync with the latest version of it by using the common code base. Since the cloud version of the database technology strives to decouple it from the underlying computing infrastructure, it doesn't support some of the context specific T-SQL features available in the traditional SQL server. However, the rest of the features are the same with incompatibilities spelled out by Microsoft. Azure SQL Database is also similar to Microsoft's SQL Managed instance offering, with some differences.

Timeline

2009 – Service announced
2010 – Service went live
2014 – New version announced and rebranded from Windows Azure to Microsoft Azure
2015 – Major Architectural Revision
2016 – Elastic Pools Introduced
2017 - Azure SQL Database Managed Instance launched
2019 - Introduced Azure SQL Database Hyperscale, Serverless, and Instance Pools

Deployment Models

Azure SQL Database is offered in two deployment models, as a Standalone database or an Elastic database pool (with shared storage and compute resources).
