What is a Serverless SQL Database?

A serverless SQL database is a type of distributed relational database that embodies the core principles of a serverless application. These include no server management, automatic elastic scale, built-in resilience and fault tolerance, consumption-based billing, and instant access with always available service. The most complex to deliver is a serverless SQL database due to its additional requirements such as distributed architecture, geographic scale, and a simple SQL API in the cloud. A true serverless SQL database allows developers to achieve native scale and global coverage without the complexity of working with a distributed database while maintaining the familiarity of SQL.
