Amazon Aurora logo

Amazon Aurora

Amazon Aurora is a fully managed relational database service (available through Amazon RDS) that is MySQL- and PostgreSQL-compatible and built for the cloud. It offers the performance and availability of high-end commercial databases at a fraction of the cost by leveraging distributed, fault-tolerant storage that can automatically scale up to 128 TB per database, with read replicas and replication for high throughput and durability.Read more
