Key points

• Aurora supports relational schemas, SQL, and transactional application access.
• Applications use database credentials or supported authentication and connection management.
• Developer scope covers access patterns and secure integration, not database fleet administration.

Best-known use cases

• Relational transactions and joins.
• Applications that need MySQL- or PostgreSQL-compatible managed relational behavior.

What candidates often confuse it with

• Aurora is relational; DynamoDB is a key-value and document database built around primary-key access.
• ElastiCache accelerates repeated access; Aurora remains the durable relational source.

Key takeaway

Choose Aurora when relational semantics are decisive and keep credential and connection behavior application-safe.
