In 2019 the developers of Aurora won the SIGMOD Systems Award for fundamentally redesigning relational database storage for cloud environments.{{cite web |title=Awards - SIGMOD/PODS 2019 |url=https://sigmod2019.org/awards |website=SIGMOD 2019 |access-date=9 August 2019}}
Features
Aurora automatically allocates database storage space in 10-gigabyte increments, as needed, up to a maximum of 128 terabytes.{{cite web|title=Amazon Aurora Increases Maximum Storage Size to 128TB|url=https://aws.amazon.com/about-aws/whats-new/2020/09/amazon-aurora-increases-maximum-storage-size-128tb/|access-date=28 September 2020}} Aurora offers automatic, six-way replication of those chunks across three availability zones for improved availability and fault-tolerance.{{Cite web|title=Amazon Aurora FAQs {{!}} MySQL PostgreSQL Relational Database {{!}} Amazon Web Services|url=https://aws.amazon.com/rds/aurora/faqs/|access-date=2021-03-09|website=Amazon Web Services, Inc.|language=en-US}}
Aurora provides users with performance metrics, such as query throughput and latency.{{cite web|title=Monitoring Amazon Aurora performance metrics|date=November 19, 2015|url=https://www.datadoghq.com/blog/monitoring-amazon-aurora-performance-metrics/|publisher=Datadog|access-date=15 September 2016}} It provides fast database cloning.{{Cite web|url=https://aws.amazon.com/blogs/aws/amazon-aurora-fast-database-cloning/|title=Amazon Aurora Fast Database Cloning|date=2017-08-30|website=Amazon Web Services|language=en-US|access-date=2019-04-12}}
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.{{cite web|title=Amazon Aurora Multi-Master is Now Generally Available|url=https://aws.amazon.com/about-aws/whats-new/2019/08/amazon-aurora-multimaster-now-generally-available/}}
Amazon designed Aurora to be compatible with MySQL, meaning that tools for querying or managing MySQL databases (such as the {{Mono|mysql}} command-line client and the MySQL Workbench graphical user-interface) can be used. As of December 2021, Amazon Aurora is compatible with MySQL 5.6, 5.7, and 8.0.{{cite web|title=Amazon Aurora supports MySQL 8.0|url=https://aws.amazon.com/about-aws/whats-new/2021/11/amazon-aurora-mysql-8-0/|access-date=24 December 2021}} It supports InnoDB as a storage engine.{{cite web|title= Amazon Aurora Product Details |url= https://aws.amazon.com/rds/aurora/faqs/|access-date= 15 September 2016}}
