description Amazon Aurora Overview

Amazon Aurora is a cloud-native relational database engine that provides the performance and availability of high-end commercial databases with the simplicity of open-source engines like MySQL and PostgreSQL. It features a distributed, fault-tolerant storage system that automatically replicates data across three Availability Zones. Aurora is designed to handle massive scale while maintaining standard SQL compatibility, making it a primary choice for enterprise applications on AWS.

help Amazon Aurora FAQ

Is Amazon Aurora compatible with MySQL and PostgreSQL?

Yes. Amazon Aurora is offered in MySQL-compatible and PostgreSQL-compatible editions, so many applications can use familiar drivers and SQL behavior.

What makes Aurora different from standard Amazon RDS?

Aurora uses a cloud-native distributed storage layer rather than a traditional single-instance database storage model. AWS describes Aurora storage as replicated across multiple Availability Zones for durability and availability.

What is Aurora Serverless?

Aurora Serverless is an on-demand configuration that can scale database capacity based on workload. It is commonly used when traffic is variable and the team does not want to size a fixed database instance manually.

When would Aurora be too much for a project?

Aurora can be more complex and more expensive than a small RDS MySQL or PostgreSQL instance for low-traffic apps. A simple internal tool or prototype may not need Aurora's multi-AZ storage architecture.
