Amazon Aurora Global Database vs Cloud SQL Enterprise Plus edition features (HA, advanced DR, managed connection pooling) / AlloyDB for PostgreSQL
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.
Side-by-side comparison
| Aspect | Amazon Web Services | Google Cloud |
|---|---|---|
| Service | Amazon Aurora Global Database | Cloud SQL Enterprise Plus edition features (HA, advanced DR, managed connection pooling) AlloyDB for PostgreSQL |
| Lifecycle | Generally available | Generally available Generally available |
| What it is | One primary Region for writes and up to 10 read-only secondary Regions, using storage-level replication, with managed switchover and failover, and optional write forwarding. | Regional HA instances, cross-region DR replicas with switchover, and managed connection pooling (Enterprise Plus) for Cloud SQL. Fully managed PostgreSQL-compatible database with disaggregated storage, read pool instances, a columnar engine, and cross-region secondary clusters. |
| Pricing model | Secondary clusters are billed as normal Aurora clusters, plus replicated write I/O and cross-Region transfer. | Cross-region replicas or secondary clusters are billed as separate instances, plus inter-region transfer. |

Key differences
- 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.

FAQ
What is the Google Cloud equivalent of Amazon Aurora Global Database?
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.
How does pricing compare between Amazon Aurora Global Database and Cloud SQL Enterprise Plus edition features (HA, advanced DR, managed connection pooling) and AlloyDB for PostgreSQL?
AWS: Secondary clusters are billed as normal Aurora clusters, plus replicated write I/O and cross-Region transfer. Google Cloud: Cross-region replicas or secondary clusters are billed as separate instances, plus inter-region transfer. Check the official pricing pages for current rates.
What is the Azure equivalent?
Azure SQL active geo-replication and failover groups and Read replicas (PostgreSQL, MySQL) (partial match). Aurora Global Database maps to Azure SQL active geo-replication and failover groups (for Azure SQL), and to cross-region read replicas for Azure Database for PostgreSQL and MySQL.
