8.0
Users achieved strong ROI from MongoDB Atlas through cost savings, fast performance, and efficient cloud-based data management despite high support costs.
Sentiment score
6.5
Implementing Redis improved transaction efficiency, reduced costs, enhanced performance, increased developer effectiveness, and supported scalability for organizations.
 

Customer Service

Sentiment score
7.0
MongoDB Atlas customer service is praised for knowledgeable premium support, with faster responses in higher-tier plans despite some cost concerns.
Sentiment score
1.0
Users rarely contact Redis support, but those who do find it knowledgeable, with satisfaction levels ranging from moderate to excellent.
The features of MongoDB Atlas fall short, resulting in an average rating due to higher-expectation features still lacking in its offerings.
I have used them sometimes, even recently, and found the feedback to be spot on our needs.
For premium support, I would rate the support of MongoDB Atlas a nine.
 

Scalability Issues

Sentiment score
7.6
MongoDB Atlas effectively scales from gigabytes to terabytes, handling thousands of users, though shard management can be challenging.
Sentiment score
7.7
Redis excels in scalability, efficiently handling large datasets with ease, making it ideal for enterprise-level operations and demands.
It's very much scalable, and I would rate scalability a nine.
MongoDB Atlas offers sharding as a scalability feature, although it does not perform as well as Oracle.
Data migration and changes to application-side configurations are challenging due to the lack of automatic migration tools in a non-clustered legacy system.
 

Stability Issues

Sentiment score
7.9
MongoDB Atlas is highly reliable, efficiently handling workloads with automatic updates, despite minor interface issues, and is user-trusted.
Sentiment score
7.7
Redis is stable, reliable under heavy loads, supports high availability, and user ratings reflect strong performance, needing load improvements.
When it comes to OLTP transactions, its performance declines.
The stability of the product is very high.
Redis is fairly stable.
 

Room For Improvement

MongoDB Atlas users seek UI improvements, cost reduction, better integration, scalability, and enhanced security, training, APIs, and support.
Enhancements in documentation, user-friendliness, scalability, security, cloud integration, and support are desired improvements for Redis.
Enhancing vector processing for AI capabilities would also be critical.
MongoDB Atlas should support containerization.
Data persistence and recovery face issues with compatibility across major versions, making upgrades possible but downgrades not active.
 

Setup Cost

Enterprise buyers find MongoDB Atlas pricing acceptable, yet opinions on cost-effectiveness differ; the free tier enhances its appeal.
Redis's open-source core is cost-effective, but enterprise features require a license; managed services start at $5/month.
The price of MongoDB Atlas is reasonable, which is why many organizations, including mine, are opting for it.
For our service, it was around 300 to 600 euros per month, which was acceptable for our customers.
Since we use an open-source version of Redis, we do not experience any setup costs or licensing expenses.
 

Valuable Features

MongoDB Atlas offers speed, flexibility, easy scalability, and advanced features for efficient data management, enhancing performance and reducing costs.
Redis provides fast data access with caching, geolocation, JSON, and supports scalability, high availability, and efficient event-driven applications.
The most valuable features of MongoDB Atlas in handling large data volumes include collection size and its NoSQL database capabilities.
I find MongoDB Atlas highly scalable and easy to use, with very good support.
It is particularly useful for unstructured and semi-structured data because of its performance in these areas.
It functions similarly to a foundational building block in a larger system, enabling native integration and high functionality in core data processes.

Featured Reviews

Laksiri Bala - PeerSpot reviewer
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.
Yaseer Arafat - PeerSpot reviewer
Unmatched Performance and Scalability for Modern Applications
Redis has room for improvement in a few areas. Enhanced tools for managing and monitoring clusters would be beneficial, as would built-in security mechanisms like advanced encryption and granular access controls. Simplifying setup and configuration could make Redis more accessible to new users. Introducing more enterprise-grade features, such as better multi-tenancy support and improved backup and restore capabilities, would also be advantageous. For the next release, it would be great to see enhanced cluster management tools, native multi-region supports for better data redundancy, integrated analytics for deeper insights, AI and ML integration features, and improved developer experience through enhanced SDKs and tools.
