Mappings (3)
Cloud-native PostgreSQL (separate compute and storage) Direct match
Aurora PostgreSQL maps to AlloyDB for PostgreSQL, a PostgreSQL-compatible database with disaggregated storage, read pool instances, and a columnar engine for analytics.
- AlloyDB's columnar engine accelerates analytical queries inside the operational database.
- Storage is billed for what you use, like Aurora; compute is billed by primary and read pool machine size.
Cross-region relational disaster recovery Partial match
Aurora Global Database maps partly to Cloud SQL advanced DR (Enterprise Plus cross-region DR replicas with failover and zero-data-loss switchover) and AlloyDB cross-region secondary clusters.
- Replication is asynchronous; replica failover can lose recent writes, while planned switchover has zero data loss.
- For multi-region writes with strong consistency, use Spanner.
Database connection pooling Direct match
RDS Proxy maps to managed connection pooling in Cloud SQL (Enterprise Plus edition) and AlloyDB.
- Managed connection pooling in Cloud SQL requires Enterprise Plus edition.
- The Cloud SQL Auth Proxy is a secure connector, not a pooler.
