Amazon Aurora is a fully managed relational database engine that's compatible with MySQL and PostgreSQL. In addition to all the benefits of open source, Aurora combines a high-performance storage subsystem to offer you options in terms of choosing the right solution for your high availability (HA) and disaster recovery (DR) needs on Amazon Web Services (AWS). This guide provides an in-depth look at three powerful features:
Aurora Replicas
Cross-Region Aurora Replicas
Aurora global databases
Each of these three options support replicating your production Aurora database beyond the capabilities of a single machine. Choosing among these options can be challenging.
