Room For Improvement

Users seek improvements in DynamoDB's documentation, interface, querying, cost management, integration, schema complexity, and encryption support.
MongoDB Atlas faces challenges in cost management, configuration, UI stability, performance, integration, support, security, and containerization.
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 have mixed opinions on MongoDB Atlas pricing, finding it either cost-effective or expensive, especially with support.
Amazon DynamoDB can be quite expensive due to regional differences, so I have to be careful with the pricing.

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.
Lintz Veloso - PeerSpot reviewer
IT Manager at a government with 11-50 employees
Developers have benefited from flexibility and performance but pricing has needed further attention
I am only familiar with databases and applications. I am from the development team and I am a user of database and cloud but I don't know the infrastructure. As a user, I deal with the Oracle Database. I know the organization has a license with the product. We don't utilize real-time analytics with MongoDB Atlas. I don't use MongoDB Atlas directly, so I don't know how it can be improved. I would place MongoDB Atlas at a medium level. I would rate it at a six or seven. I believe MongoDB Atlas can improve a little. My overall review rating for this product is six out of ten.
