The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Amazon RDS.
- No super-user access or direct host connectivity limits advanced customization
- Pricing unpredictable and expensive compared to GCP alternatives with equivalent features
- Limited access to system procedures and tables requiring advanced permissions
- No Oracle RAC (Real Application Clusters) support for high-availability Oracle deployments

Softwr does not host reviews and shows no star rating for Amazon RDS, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
