Aurora

What it is: A high-performance managed relational database compatible with MySQL or PostgreSQL.

What it’s for:

• Higher throughput and better scalability than standard RDS engines (common AWS positioning).
• Managed HA and read scaling with replicas.

Key ideas:

• Aurora uses a cluster concept with:
  • Writer (primary)
  • Multiple reader replicas
• Often used for high availability and scaling.

Exam cues:

• “MySQL/Postgres compatible but higher performance and HA” → Aurora.
