What is AuroraAURORA 101

Amazon Aurora is a MySQL/PostgreSQL compatible, relational database engine that combines the speed and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. Amazon Aurora provides up to five times better performance than MySQL (and three times better performance than PostgreSQL) at a price point one tenth that of a commercial database while delivering similar performance and availability.

• Start with 10GB, Scales in 10GB increments to 64TB (Storage Autoscaling)

• Compute resources can scale up to 64vCPUs and 488GiB of Memory.

• 2 copies of your data is contained in each availability zone, with minimum of 3 availability zones. 6 copies of your data.

Aurora ScalingAURORA 101

• Aurora is designed to transparently handle the loss of up to two copies of data without affecting database write availability and up to three copies without affecting read availability.

• Aurora storage is also self-healing. Data blocks and disks are continuously scanned for errors and repaired automatically.
