An Amazon Aurora Global Database is a single database that can span up to 6 AWS Regions, enabling disaster recovery from region-wide outages and low latency global reads. With today’s launch, you can seamlessly change your global cluster’s primary AWS Region, the region that serves writes, while preserving the replication between all regions in the global cluster. With this managed planned failover capability, you can repeatedly change which AWS Region hosts the primary cluster while preserving the physical topology of your global database and avoiding unnecessary application changes. Aurora Global Database managed planned fail over simplifies the planned fail over process in scenarios like rotating the primary region for regulatory compliance or disaster recovery exercises. Check out this blog to learn how to perform managed planned failovers with Global Database.
Aurora Global Database replicates database changes from the primary to the secondary regions with typical latency of <1 second, enabling both fast failover with minimal data loss and low latency global reads. In unplanned disaster recovery situations, you can promote any secondary AWS Region to take full read-write responsibilities in under a minute. Global Database is available for both the MySQL-compatible and PostgreSQL-compatible editions of Aurora in 14 AWS regions. See Amazon Aurora Pricing for a complete list.
Amazon Aurora combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. It provides up to five times better throughput than standard MySQL and up to three times better throughput than standard PostgreSQL together with increased scalability, durability, and security.
