The intelligent relational cloud database service
Azure SQL Database is intelligent, fully managed relational cloud database service which provides the broadest SQL Server engine compatibility, so you can migrate your SQL Server databases without changing your apps. Accelerate app development and make maintenance easy and productive using the SQL tools you love to use. Take advantage of built-in intelligence that learns app patterns and adapts to maximize performance, reliability and data protection.
Migrate your SQL Server databases without changing your apps
SQL Database Managed Instance provides the broadest SQL Server engine compatibility and native virtual network (VNET) support so you can migrate your SQL Server databases to SQL Database Managed Instance without changing your apps. With Managed Instance, you can combine the rich SQL Server surface area with the operational and financial benefits of an intelligent, fully managed service. Managed Instance is your best destination when migrating many existing SQL Server databases from on-premises or virtual machines to SQL Database.
Tune and protect your database with built-in intelligence
SQL Database uses the built-in intelligence that learns your unique database patterns and automatically tunes the database for improved performance and protection. Threat Detection monitors your database around-the-clock and detects potential malicious activities, alerting you upon detection so you can intervene right away.
Secure your app data and ensure availability
Build security-enhanced apps in the cloud with advanced built-in protection and security features that dynamically mask sensitive data and encrypt it at rest and in motion. Ensure high availability with three hot replicas and built-in automatic failover that guarantees a 99.99% availability SLA. Accelerate recovery from catastrophic failures and regional outages to an RPO of less than five seconds with active-geo replication. With physical and operational security, SQL Database helps you meet the most stringent regulatory compliances, such as ISO/IEC 27001/27002, Fed-RAMP/FISMA, SOC, HIPPA and PCI DSS.
Optimise performance for your workloads
When the demand for your app grows from a handful of devices and customers to millions, SQL Database scales on the fly with minimal downtime. Additionally, SQL Database provides in-memory OLTP that improves throughput and latency on transaction processing workloads up to 30 times over traditional table and database engines and delivers faster business insights with up to 100 times faster queries and reports over traditional row-oriented storage.
Work in your preferred development environment
SQL Database allows you to focus on what you do best—building great apps. Seamlessly enable DevOps by developing in SQL Server containers and deploying in SQL Database with the easy-to-use tools you already have, such as Visual Studio and SQL Server Management Studio. Or, build your applications with Python, Java, Node.js, PHP, Ruby and .NET on the MacOS, Linux, and Windows platforms, and deliver with the speed and efficiency your business demands.
Build multitenant apps with customer isolation and efficiency
If you’re a software as a service (SaaS) app developer writing a multitenant app that serves many customers, you often must make trade-offs in customer performance, efficiencies and security. SQL Database removes the compromise and helps you maximize your resource utilization and manage thousands of databases as one while ensuring one-customer-per-database with elastic pools.
