Customer Service

Sentiment score
6.6
MongoDB Atlas support is mixed; valued for expertise and options, but criticized for cost and varying responsiveness.
Sentiment score
6.4
Redis users rarely need support due to stability, relying on documentation and community, with mixed experiences reported.
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.
DB Architect / Consultant at Virtusa Global
For premium support, I would rate the support of MongoDB Atlas a nine.
General Manager at Kaleyra
By simply referring to their documentation, we have been able to fix our bugs and general issues.
Senior Software Engineer at a consultancy with 1-10 employees
Since Redis is quite stable and well-documented, we have not needed much support, but when required, the response has been helpful.
SDE 2 at Virtusa
 

Scalability Issues

Sentiment score
7.4
MongoDB Atlas is commended for effective scalability features like horizontal scaling and sharding, suitable for diverse workloads.
Sentiment score
7.8
Redis excels in scalability and efficiency, handling high traffic with clustering and sharding, benefiting enterprise application demands.
It's very much scalable, and I would rate scalability a nine.
General Manager at Kaleyra
MongoDB Atlas offers sharding as a scalability feature, although it does not perform as well as Oracle.
DB Architect / Consultant at Virtusa Global
The in-memory architecture provides consistently low-latency access even as data access patterns and request volume increase.
Senior Software Engineer at a consultancy with 1-10 employees
Data migration and changes to application-side configurations are challenging due to the lack of automatic migration tools in a non-clustered legacy system.
Data Engineer at a photography company with 1,001-5,000 employees
With features such as clustering and replication, it can handle high traffic and a large database very effectively.
SDE 2 at Virtusa
 

Stability Issues

Sentiment score
7.9
MongoDB Atlas is praised for reliability and performance, with users rating its stability highly despite occasional UI concerns.
Sentiment score
7.9
Redis is lauded for its stability, reliable caching performance, and robust architecture, supported by strong community and managed services.
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
Redis has consistently provided fast and predictable performance, particularly for caching and high-frequency data access scenarios.
Senior Software Engineer at a consultancy with 1-10 employees
Redis is fairly stable.
Data Engineer at a photography company with 1,001-5,000 employees
 

Room For Improvement

MongoDB Atlas faces challenges in cost management, configuration, UI stability, performance, integration, support, security, and containerization.
Redis users seek improvements in cache management, user interface, observability, scalability, security setup, and cloud integrations for enhanced usability.
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
Making security features and enterprise governance capabilities easier to configure out of the box would help organizations adopt Redis more confidently for larger and more critical workloads.
Senior Software Engineer at a consultancy with 1-10 employees
Data persistence and recovery face issues with compatibility across major versions, making upgrades possible but downgrades not active.
Data Engineer at a photography company with 1,001-5,000 employees
Redis itself does not enforce consistency with the primary database, so developers need to carefully design cache invalidation strategies.
Software Engineer at ValueMomentum
 

Setup Cost

Enterprise buyers have mixed opinions on MongoDB Atlas pricing, finding it either cost-effective or expensive, especially with support.
Enterprise Redis costs vary by deployment model, with self-managed being cost-effective and cloud services charging for memory usage.
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
The main value comes from the performance improvements, reduced database load, and increased scalability that Redis provides.
Senior Software Engineer at a consultancy with 1-10 employees
Since we use an open-source version of Redis, we do not experience any setup costs or licensing expenses.
Data Engineer at a photography company with 1,001-5,000 employees
The pricing is reasonable for the performance provided.
SDE 2 at Virtusa
 

Valuable Features

MongoDB Atlas offers scalability, security, and easy management, enabling efficient development with reduced operational overhead and reliable performance.
Redis is preferred for speed and reliability, offering low latency, high throughput, and efficient scaling with minimal configuration.
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
The most valuable features of MongoDB Atlas in handling large data volumes include collection size and its NoSQL database capabilities.
General Manager at Kaleyra
It functions similarly to a foundational building block in a larger system, enabling native integration and high functionality in core data processes.
Data Engineer at a photography company with 1,001-5,000 employees
First is its in-memory preference, as Redis is extremely fast, making it ideal for caching and session management where low latency is critical.
Software Engineer at ValueMomentum
By offloading frequent reads from the database and enabling fast in-memory cache access, it reduced latency, improved throughput, and helped maintain stability during peak loads.

Featured Reviews

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.
RituRaj - PeerSpot reviewer
SDE 2 at Virtusa
Caching has improved response times and reduces database load for high-traffic applications
Redis is very reliable, but it could be improved in areas such as monitoring, debugging, and feasibility into memory use. Better built-in tools for observability would help teams manage it more effectively at scale. Managing memory efficiently and troubleshooting issues can sometimes require additional tooling, so these areas can also be improved.One practical challenge I experienced is managing memory efficiently. Since Redis is in-memory, we need to carefully configure eviction policies and monitor usage. Debugging cache-related issues such as stale data or cache invalidation can sometimes be tricky. Additionally, tuning memory usage and eviction policies needs to be planned very carefully.
