Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.6
Azure Database for PostgreSQL offers significant cost savings and efficiency improvements, reducing ownership costs by eliminating expensive licenses.
Sentiment score
7.9
Organizations benefit from MongoDB Atlas through cost savings, engineering efficiency, enhanced performance, and reduced operational costs despite support concerns.
It offers at least 25 percent cost savings compared to maintaining on-premises databases.
Now, we use embedded PostgreSQL vectors, which will undoubtedly reduce the TCO by using a much more cost-effective solution.
We've reduced our total ownership cost because we are not spending on expensive SQL server licenses.
 

Customer Service

Sentiment score
7.4
Users praise Microsoft Learn's documentation, benefit from fast support response, and find engineering engagement insightful for urgent issues.
Sentiment score
6.9
MongoDB Atlas support is praised for expertise and responsiveness but criticized for cost and occasional first-level support delays.
Once we open a support case, we have people engaged within about 20 minutes, especially for a Sev 1 issue.
The documentation and training we've received through Microsoft Learn on how to migrate, deploy, and manage the solution is exceptional.
We handle most implementations in-house, without extensive reliance on Microsoft's technical support.
I have used them sometimes, even recently, and found the feedback to be spot on our needs.
The features of MongoDB Atlas fall short, resulting in an average rating due to higher-expectation features still lacking in its offerings.
 

Scalability Issues

Sentiment score
7.9
Azure Database for PostgreSQL efficiently scales workloads with FlexServer, offering easy resizing for large enterprises and government projects.
Sentiment score
7.6
MongoDB Atlas offers scalable, reliable, and easy-to-use data solutions, accommodating growth with high ratings despite some technical challenges.
However, we can see how well it scales after we deploy it for some large enterprise customers or big government organizations.
The scaling options with FlexServer provide us with the flexibility we need based on application complexity.
We can scale up compute and scale it down, but once storage is allocated, there is no way to scale it back down.
MongoDB Atlas offers sharding as a scalability feature, although it does not perform as well as Oracle.
 

Stability Issues

Sentiment score
7.0
Azure Database for PostgreSQL is stable with no latency issues, though it may crash during peak usage without auto-healing.
Sentiment score
7.9
MongoDB Atlas offers stable performance with auto-scaling, despite occasional UI issues, and supports critical applications effectively.
There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality.
We have generative AI applications, and we have not noticed any latency.
Overall, I have not encountered any real latency issues or stability concerns.
When it comes to OLTP transactions, its performance declines.
 

Room For Improvement

Azure Database for PostgreSQL needs faster scaling, better reliability, extensions, user management, cost efficiency, support, and error detection.
MongoDB Atlas requires enhanced UI, optimized processes, better integration, security, performance improvements, and user-friendly documentation and support.
It does not presently support knowledge graph functionalities as Neo4j does.
Azure Database for PostgreSQL can be improved by allowing quicker scaling without blips.
I believe there could be improvements in the mirroring part and Change Data Capture (CDC).
Enhancing capabilities for data pipelines and visualization dashboards.
 

Setup Cost

Enterprise buyers appreciate Azure's cost-efficient, pay-as-you-go pricing for PostgreSQL, reducing on-premises database costs significantly.
MongoDB Atlas is competitively priced with flexible pay-as-you-go options, though technical support can be costly.
We've reduced costs by 60 percent compared to maintaining on-premises solutions.
The pay-as-you-go pricing model positively affects database-related costs by allowing us to start small and scale as needed.
The pay-as-you-go model works well for us.
For our service, it was around 300 to 600 euros per month, which was acceptable for our customers.
The price of MongoDB Atlas is reasonable, which is why many organizations, including mine, are opting for it.
 

Valuable Features

Azure Database for PostgreSQL offers seamless integration, robust networking, efficient AI tools, and strong security with a positive cost-benefit ratio.
MongoDB Atlas excels in scalability, user-friendliness, security, and cost-effectiveness, supporting diverse workloads with seamless integrations and robust performance.
My takeaway as a CTO is that they're comfortable with the security posture, the features, the observability, alerts, and now it integrates into the rest of the Azure landscape.
The query analyzers help me find out what's happening in each of the queries.
The most valuable features of Azure Database for PostgreSQL are its networking capabilities, which allow for integration with other Azure services.
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.

Featured Reviews

Daniel Amini - PeerSpot reviewer
An incredibly powerful industry leader that enabled us to build critical pieces of national infrastructure
Azure Database is simple and easy to use. We followed the prescribed training and upskilled 10 engineers. They think it's straightforward. They've already got PostgreSQL skills to optimize the solution, so they know what to do. It was easy to get started quickly and become effective. My team speaks highly of the platform's observability and monitoring features. It's as efficient as an enterprise needs it to be and. has all of the tooling and telemetry necessary to run an enterprise database. We take security seriously. The team has looked at the security features, and nothing has been flagged to us. My takeaway as a CTO is that they're comfortable with the security posture, the features, the observability, alerts, and now it integrates into the rest of the Azure landscape. The OpenAI integration and extensions have massively simplified integrating AI into a database. PostgreSQL's native vector capabilities are also incredibly powerful.
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.
