Seven differences that change the shortlist
| Buying question | Amazon Aurora | Azure Database for PostgreSQL |
|---|---|---|
| Cloud provider | AWS | Microsoft Azure |
| Engine scope | Aurora PostgreSQL-compatible or MySQL-compatible engine | Managed PostgreSQL |
| Deployment unit | Aurora database cluster | PostgreSQL server configuration |
| Read-capacity planning | Selected Aurora reader arrangement | Selected compute and supported replica arrangement |
| Network context | AWS VPC connectivity | Azure networking configuration |
| Compatibility check | Application compatibility with the chosen Aurora engine | PostgreSQL version, extensions and supported operations |
| Cost components | Cluster resources, storage, I/O model and readers | Server compute, storage, backups and availability configuration |
Four worked buying briefs
These are hypothetical scenarios with explicit assumptions. They do not establish equal capabilities, measured usability or a negotiated price.
| Requirement | Proposed exercise | Accept when |
|---|---|---|
| Schema compatibility | Import required schema objects and extensions. | Every mandatory object is supported by the selected configuration. |
| Application transactions | Run representative critical read and write transactions. | Results and transaction outcomes match the application specification. |
| Restore drill | Restore a test backup into a separate environment. | The restored database passes application checks. |
| Cutover plan | Rehearse application reconnection and rollback. | The team can explain the cutover and recovery sequence. |
Schema compatibility
Can the team import required schema objects and extensions?
Amazon Aurora: With Amazon Aurora, import required schema objects and extensions.
Azure Database for PostgreSQL: With Azure Database for PostgreSQL, import required schema objects and extensions.
Every mandatory object is supported by the selected configuration.
Application transactions
Can the team run representative critical read and write transactions?
Amazon Aurora: With Amazon Aurora, run representative critical read and write transactions.
Azure Database for PostgreSQL: With Azure Database for PostgreSQL, run representative critical read and write transactions.
Results and transaction outcomes match the application specification.
Restore drill
Can the team restore a test backup into a separate environment?
Amazon Aurora: With Amazon Aurora, restore a test backup into a separate environment.
Azure Database for PostgreSQL: With Azure Database for PostgreSQL, restore a test backup into a separate environment.
The restored database passes application checks.
Cutover plan
Can the team rehearse application reconnection and rollback?
Amazon Aurora: With Amazon Aurora, rehearse application reconnection and rollback.
Azure Database for PostgreSQL: With Azure Database for PostgreSQL, rehearse application reconnection and rollback.
The team can explain the cutover and recovery sequence.
Scope and architecture
A PostgreSQL comparison should use Aurora PostgreSQL, not Aurora MySQL. Review the selected cluster or server configuration, supported extensions and recovery process in the cloud where the application will run.
The service family name is not the database engine. Select the engine, version, extensions, availability configuration and connection behaviour before making an engine-compatible comparison.

Cost and migration planning
For Amazon Aurora, include cluster resources, storage, I/O model and readers. For Azure Database for PostgreSQL, include server compute, storage, backups and availability configuration. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.
Import representative schemas and data, then run the application's critical queries and transactions. Check extensions, privileged operations, maintenance behaviour and restore procedures before planning a production cutover.
Questions before you choose
How should we choose between Amazon Aurora and Azure Database for PostgreSQL?
A PostgreSQL comparison should use Aurora PostgreSQL, not Aurora MySQL. Review the selected cluster or server configuration, supported extensions and recovery process in the cloud where the application will run.
Which costs belong in the comparison?
For Amazon Aurora, include cluster resources, storage, I/O model and readers. For Azure Database for PostgreSQL, include server compute, storage, backups and availability configuration. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.
What should we validate before a production move?
Import representative schemas and data, then run the application's critical queries and transactions. Check extensions, privileged operations, maintenance behaviour and restore procedures before planning a production cutover.
