The official AWS technical support for Amazon RDS is helpful, providing 24/7 assistance for all business support cases with tools such as the health dashboard and AWS trusted advisor.
AWS Architect at Virtual University
I would rate the support from AWS very high, maybe nine, but it also depends on what kind of support you have signed in your contract, whether the premium support or the standard support.
Director Software Engineer at a computer software company with 10,001+ employees
I have used them sometimes, even recently, and found the feedback to be spot on our needs.
Partner at Red software systems
The features of MongoDB Atlas fall short, resulting in an average rating due to higher-expectation features still lacking in its offerings.

Since it is a managed service, features like replication, automatic failover, and backups are handled by the platform.
Senior Software Developer at NIT
When it comes to OLTP transactions, its performance declines.
DB Architect / Consultant at Virtusa Global
The stability of the product is very high.
General Manager at Kaleyra
 

Room For Improvement

Amazon RDS users seek improvements in security, documentation, scalability, integration, and support, with enhanced customization and cost reduction.
Users seek MongoDB Atlas enhancements in data processes, integration, UI, performance, scalability, documentation, and cost efficiency.
Simplifying migration for those transitioning from on-premises to cloud environments.
AICE Graduate at alx_africa
Having native Change Data Capture (CDC) support would be beneficial, allowing for seamless integration with Kafka without relying on external technologies like Debezium.
VP engineering at a computer software company with 1,001-5,000 employees
Enabling performance insights to view query formats where the bottlenecks occur, identifying the fixes, slow queries, and missing indexes.
AWS Architect at Virtual University
Enhancing capabilities for data pipelines and visualization dashboards.
DB Architect / Consultant at Virtusa Global
MongoDB Atlas should support containerization.
General Manager at Kaleyra
The UI is good, although I have checked one aspect in MongoDB Atlas: when we make transactions, they do not process in real-time and require a refresh.
Software Developer at Styx Global
 

Setup Cost

Amazon RDS pricing is usage-dependent and cost-effective, offering savings on admin costs but can be expensive compared to alternatives.
Enterprise buyers find MongoDB Atlas competitively priced, valuing its pay-as-you-go model, flexibility, and minimal initial setup expense.
While Azure provides great services, long-term plans on AWS are 20% to 30% cheaper.
AWS Engineer at Neurolov.ai
I find the pricing of Amazon RDS fair, as AWS operates on a pay-for-what-you-use model.
AICE Graduate at alx_africa
I rate the price for Amazon as eight on a scale from one to ten.
Corporate Database Architect at a tech services company with 201-500 employees
For our service, it was around 300 to 600 euros per month, which was acceptable for our customers.
Partner at Red software systems
The price of MongoDB Atlas is reasonable, which is why many organizations, including mine, are opting for it.
DB Architect / Consultant at Virtusa Global
 

Valuable Features

Amazon RDS provides scalability, security, and flexibility with multi-engine support and simplified operations for diverse applications.
MongoDB Atlas excels in scalability, security, usability, and efficiency, effectively handling unstructured data and reducing operational costs.
Amazon RDS provides data encryption using services like KMS, crucial for securing high-sensitive data and meeting compliance requirements such as HIPAA or PCI DSS.
AICE Graduate at alx_africa
Database management is effective in Amazon RDS because it offers automated backups, high availability, read replicas, and support from multiple database engineers, while also providing security, monitoring and metrics, scalability.
AWS Architect at Virtual University
In some cases, we are using the read replica feature, and it does improve our application performance because we do not allow any downstream system to come to the main storage or main databases and perform a query.
Director Software Engineer at a computer software company with 10,001+ employees
MongoDB Atlas is a fully managed service, meaning it handles deployment, scaling, backup, patching, and maintenance automatically, which allows developers to focus more on application logic instead of infrastructure.
Senior Software Developer at NIT
I find MongoDB Atlas highly scalable and easy to use, with very good support.
Partner at Red software systems
It is particularly useful for unstructured and semi-structured data because of its performance in these areas.
DB Architect / Consultant at Virtusa Global

AWS Architect at Virtual University
Customer support and automated backups offer reliability while ease of deployment enhances user experience
The features of Amazon RDS that I have found most valuable include web and mobile applications, enterprise applications, data warehousing and analytics, and software as a service platforms, along with dev testing environments, disaster recoveries, and backups. The mobile app backend and development environment is also the best feature for database management for my customers. Database management is effective in Amazon RDS because it offers automated backups, high availability, read replicas, and support from multiple database engineers, while also providing security, monitoring and metrics, scalability. We are using snapshots and database migrations as well as performance optimization. The impact of Amazon RDS scalability and backup has been positive, with good vertical scaling, scale up and down, horizontal scaling, and storage scaling. The performance was good and availability helped with reducing downtime.
Varuns Ug - PeerSpot reviewer
Senior Software Developer at NIT
Flexible document workflows have accelerated schema changes and simplified evolving data models
MongoDB Atlas currently has almost all the features we require, but there are some points where I see certain improvements. One area is cost visibility and optimization. Since pricing is largely based on storage and cluster size, it can sometimes be difficult to predict or optimize cost without deeper insights. More granular cost breakdowns or recommendations would be helpful. Another area I can mention is performance tuning transparency. While MongoDB Atlas provides monitoring and suggestions, debugging deeper issues like slow queries, index efficiency, or shard imbalance can sometimes require more control or visibility. Cost optimization, deeper performance insight, and easier scaling decisions would make MongoDB Atlas even more powerful. A couple of additional areas where MongoDB Atlas could improve are integrations and developer experience. For integrations, while MongoDB Atlas supports major cloud providers and tools, deeper and more seamless integration with observability patterns would make troubleshooting distributed systems easier. On the documentation side, while it is generally good, some advanced topics like sharding strategies, performance tuning, and real-world scaling patterns could benefit from more practical guidance. Additionally, a better local-to-cloud development experience, making it easier to replicate production-like MongoDB Atlas environments locally, would help developers test performance and scaling scenarios more efficiently.
