Executive SummaryUpdated on Oct 5, 2025

Amazon RDS and MongoDB Atlas are strong contenders in the cloud-based database management system category. User reviews indicate Amazon RDS might have a competitive edge due to its favorable pricing and reliable technical support, whereas MongoDB Atlas is appreciated for its robust features despite higher costs.

Features: Amazon RDS offers a fully managed database service supporting MySQL, Oracle, and SQL servers. It is known for high availability, automated CI/CD tools, and a straightforward setup process, facilitating efficient microservices and web application implementations. MongoDB Atlas features a schemaless architecture, rich query support, and seamless integration capabilities, providing a flexible and scalable solution ideal for both structured and unstructured data.

Room for Improvement: Amazon RDS users mention limitations in migration and customization due to restricted shell access and default disabled features. Improvements in pricing, integration with Microsoft products, and additional database support are suggested. MongoDB Atlas users highlight high costs and suggest advocacy for enhanced security and integration. A more intuitive dashboard and better performance monitoring are also on user wish lists.

Ease of Deployment and Customer Service: Amazon RDS is noted for its reliable deployment across platforms with commendable customer service, though it incurs high costs for extensive support. MongoDB Atlas offers a positive deployment experience, also praised for dedicated customer service, yet the higher cost and occasional technical issues are points of concern for users. Both function smoothly in public and hybrid cloud environments, ensuring cross-platform ease of deployment.

Pricing and ROI: Amazon RDS uses a flexible pay-as-you-go pricing model, which is appealing due to reduced need for DBAs and lower overhead. Yet high support costs and unexpected expenses are common concerns. MongoDB Atlas, despite a higher price, is valued for its significant return on investment, attributed to its advanced features and functionality specifically suited for handling unstructured data in enterprise scenarios.

Director Software Engineer at a computer software company with 10,001+ employees

Positive experiences with database services, with minor room for feature enhancements observed

I don't really see any disadvantages of Amazon RDS. With Oracle, I think AWS doesn't provide the RAC stability. If you have Oracle installed in your own data centers, you can set up various clusters and we can set up the RACs, but in Amazon RDS, we cannot have the RAC feature of Oracle. They could add that feature. Amazon RDS has limitations regarding RAC. If we talk about installing Oracle in RDS, we cannot have the RAC, but if you deploy Oracle on GCP, then there is probably the RAC feature available. I observed that around two or three years back, but I'm not sure whether they have added the RAC feature in AWS. Amazon RDS is expensive compared to GCP. GCP also has the same features, and although it is quite extensive and feature-rich, I see Amazon RDS as slightly expensive compared to other clouds.

Room for improvement in data handling leads to enhanced cost-effective data management performance

It would be beneficial if MongoDB Atlas could better support OLTP aspects and data frames, as well as enhance its capabilities for data pipelines and visualization dashboards. Furthermore, supporting the medallion architecture could be a valuable addition, and incorporating improved spatial and vector handling for geographical data could make it more competitive. Enhancing vector processing for AI capabilities would also be critical.
