SQL Database

The developer’s intelligent cloud database

Learn and adapt dynamically with your app

As your app runs, Azure SQL Database continuously learns your unique app patterns, adaptively tunes your performance, and automatically improves reliability and data protection—freeing you to focus on your app.

Scale performance on the fly, without app downtime

When demand for your app grows from a handful of devices and customers to millions, SQL Database is the database service that can scale along with you—on the fly and with no app downtime.

Build multitenant apps with customer isolation and efficiency

If you’re a SaaS app developer writing a multitenant app that services many customers, you often make tradeoffs in customer performance, management, and security. With SQL Database elastic database pools, you no longer have to make that compromise. Create elastic database pools to help you manage and monitor multitenant apps and gain isolation benefits of one customer per database.

Work within your preferred development environments
