Seven differences that change the shortlist
| Buying question | Azure Database for PostgreSQL | Amazon RDS |
|---|---|---|
| Cloud provider | Microsoft Azure | AWS |
| Engine scope | Managed PostgreSQL | Multiple supported relational database engines |
| Deployment unit | PostgreSQL server configuration | RDS database instance or selected deployment |
| Read-capacity planning | Selected compute and supported replica arrangement | Selected engine and read replica arrangement |
| Network context | Azure networking configuration | AWS VPC connectivity |
| Compatibility check | PostgreSQL version, extensions and supported operations | Exact engine version, extensions and supported operations |
| Cost components | Server compute, storage, backups and availability configuration | Instance resources, storage, I/O configuration and availability |
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. |

Scope and architecture
Compare Azure Database for PostgreSQL with the PostgreSQL configuration of RDS. RDS supports additional database engines, but those choices do not establish PostgreSQL compatibility for the application's extensions and operating requirements.
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 Azure Database for PostgreSQL, include server compute, storage, backups and availability configuration. For Amazon RDS, include instance resources, storage, I/O configuration and availability. 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.
