In cases where we accidentally deleted some records in the production environment, we were able to recover it thanks to point-in-time recovery.
Software engineer at ProminentPixel
I have not faced any issues with bugs or a breakdown in Amazon DynamoDB.
Sales Director for West Africa at Atomic Computing
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

Users seek improvements in DynamoDB's documentation, interface, querying, cost management, integration, schema complexity, and encryption support.
Users seek MongoDB Atlas enhancements in data processes, integration, UI, performance, scalability, documentation, and cost efficiency.
The main area requiring attention is the cost aspect.
Lead SRE at JavaTech
To improve Amazon DynamoDB, the challenge I faced is that you cannot essentially query with anything that you want from the table.
Software Engineer 2 at Guidewire Software
We have query limits concerning how much we can query at one single time, which becomes expensive when dealing with a large dataset, such as when we had around 10 million rows, and scanning that table was very costly.
Software engineer at ProminentPixel
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
 

Setup Cost

Amazon DynamoDB offers competitive, usage-based pricing that can become expensive with increased data and transaction volumes.
Enterprise buyers find MongoDB Atlas competitively priced, valuing its pay-as-you-go model, flexibility, and minimal initial setup expense.
Amazon DynamoDB can be quite expensive due to regional differences, so I have to be careful with the pricing.
Sales Director for West Africa at Atomic Computing
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 DynamoDB offers scalability, speed, and ease with no maintenance, cost-effectiveness, high availability, and seamless AWS integration.
MongoDB Atlas excels in scalability, security, usability, and efficiency, effectively handling unstructured data and reducing operational costs.
The primary feature is constant availability without concerns about server maintenance or ensuring database uptime, as AWS manages everything from their end.
Lead SRE at JavaTech
The best features Amazon DynamoDB offers are its performance and Global Tables, which stand out because of their capabilities and speed.
Software Engineer 2 at Guidewire Software
Scalability has significantly enhanced data retrieval speeds.
Senior Business Solutions Consultant at Conn3ct
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.

Lead SRE at JavaTech
Has improved infrastructure availability and simplified integration through reliable cloud-based data management
Amazon DynamoDB is readily available, and we do not have to worry about downtime unless there is a global outage. From a cost perspective, it presents a challenge. The primary feature is constant availability without concerns about server maintenance or ensuring database uptime, as AWS manages everything from their end. We simply set up the database and allocate it to customers according to their requirements, making it an easy and smooth transition. Regarding security, being in the cloud provides numerous security features. Amazon DynamoDB operates at the backend within our three-tier architecture. We have front hosting, business logic or application server in the middle, and databases at the backend. Additionally, we implement security layers such as SSL, creating a highly secure environment. The solution has proven to be reliable thus far.

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.
