Amazon Aurora is a relational database service built for the cloud, offering performance and availability comparable to commercial databases at a fraction of the cost. As part of the Amazon Relational Database Service (RDS), Aurora is a fully managed service, making it easier to set up, operate, and scale databases.
What is Amazon Aurora?
Amazon Aurora is a **MySQL- and PostgreSQL-**compatible relational database engine. It combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open-source databases.
Key Features of Amazon Aurora
1. High Performance
Aurora delivers up to five times the throughput of standard MySQL and up to three times that of PostgreSQL. It achieves this through a distributed, fault-tolerant storage system that automatically scales up to 128 TB per database instance.
2. Fault Tolerance and High Availability
Aurora’s storage is designed for 99.99% availability and automatically replicates data across multiple Availability Zones (AZs). This ensures minimal downtime and data durability.
3. Fully Managed
As a managed service, Aurora automates administrative tasks such as hardware provisioning, database setup, patching, backups, and recovery. This allows developers to focus on building applications instead of managing infrastructure.
4. Global Database Support
Aurora’s Global Database feature enables replication across multiple AWS Regions, providing low-latency global reads and disaster recovery with minimal downtime.
5. Scalability
Aurora allows you to scale database instances up or down based on workload requirements. You can also add up to 15 low-latency read replicas to improve read performance.
