Amazon Aurora is a proprietaryrelational database offeredas a service byAmazon Web Services (AWS) since October 2014.^[1][2] Aurora is available as part of theAmazon Relational Database Service (RDS).

Aurora offeredMySQL compatible service upon its release in 2014. It addedPostgreSQL compatibility in October 2017.^[3]

In August 2017, Aurora Fast Cloning (copy-on-write) feature was added allowing customers to create copies of their databases.^[4] In May 2018, Aurora Backtrack was added which allows developers to rewind database clusters without creating a new one.^[5] It became possible to stop and start AuroraClusters in September 2018.^[6] In August 2018, Amazon began to offer aserverless version.^[7][8]

In 2019 the developers of Aurora won theSIGMOD Systems Award for fundamentally redesigning relational database storage for cloud environments.^[9]

Aurora automatically allocates database storage space in 10-gigabyte increments, as needed, up to a maximum of 128terabytes.^[10] Aurora offers automatic, six-wayreplication of those chunks across threeavailability zones for improved availability andfault-tolerance.^[11]

Aurora provides users with performance metrics, such asquery throughput andlatency.^[12] It provides fast database cloning.^[13]

Aurora Multi-Master allows creation of multiple read-write instances in an Aurora database across multiple availability zones, which enables uptime-sensitive applications to achieve continuous write availability through instance failure.^[14]

Amazon designed Aurora to be compatible with MySQL, meaning that tools for querying or managing MySQL databases (such as themysql command-line client and theMySQL Workbench graphical user-interface) can be used. As of December 2021, Amazon Aurora is compatible with MySQL 5.6, 5.7, and 8.0.^[15] It supportsInnoDB as a storage engine.^[16]
