Comparison Buyer's Guide

Executive SummaryUpdated on Jul 31, 2025

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
5.1
Experiences with MongoDB Enterprise Advanced's ROI vary, with some noting gains and others facing cost-related challenges; opinions differ.
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.
Actually, with MongoDB, it's difficult to calculate the return on investment; it's too expensive for our use.
 

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
6.2
MongoDB Enterprise Advanced offers technical support, with varying feedback, while many rely on community resources for issue resolution.
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.
 

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 Enterprise Advanced is scalable and adaptable, though users face challenges with manual scaling, sharding, and cost concerns.
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.
In CosmoDB, the scalability is much better than with the MongoDB ReplicaSet models.
MongoDB is highly scalable.
Overall, on a scale of one to ten, I would rate MongoDB an eight; it's mostly because we're still running a monolithic environment on old hardware, so there are some limitations with read-write access.
 

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
7.6
MongoDB Enterprise Advanced is highly stable and reliable, with few users experiencing minor bugs or stability issues.
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.
 

Room For Improvement

Azure Database for PostgreSQL needs faster scaling, better reliability, extensions, user management, cost efficiency, support, and error detection.
MongoDB Enterprise Advanced requires security, scalability, integration, and UI improvements, along with better documentation and support for enhanced usability.
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).
While solutions for other databases like SQL or PostgreSQL already exist, MongoDB requires additional integrations for developing AI solutions.
We have not contracted the security options in our contract because they're too expensive; thus, we implement just encrypted databases and not the security pack.
 

Setup Cost

Enterprise buyers appreciate Azure's cost-efficient, pay-as-you-go pricing for PostgreSQL, reducing on-premises database costs significantly.
MongoDB Enterprise Advanced is competitively priced against Oracle, with cloud options more affordable and ideal for large-scale operations.
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.
We use the free version of MongoDB, so there are no licensing costs.
We have to pay approximately 2,000 euros per month for MongoDB.
 

Valuable Features

Azure Database for PostgreSQL offers seamless integration, robust networking, efficient AI tools, and strong security with a positive cost-benefit ratio.
MongoDB Enterprise Advanced provides scalable, flexible NoSQL solutions, offering fast performance, robust security, and easy integration for efficient data management.
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.
It offers flexibility in schema adaptation, allowing us to change the schema and add new data points.
In ReplicaSet, it's acceptable, but if your workload needs more performance, and you must pass to a Sharding model, it becomes complicated in MongoDB; in Cosmos DB, however, it's simple.
MongoDB has definitely helped us improve our network monitoring and reporting dashboard.

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.
Uzair Faruqi - PeerSpot reviewer
Transforms data flow with adaptable schema and smooth public cloud deployment
One of our business units uses MongoDB, and we developed an ETL pipeline that extracts data from MongoDB and transfers it into our data warehouse MongoDB is a NoSQL database that is similar to a document database. It offers flexibility in schema adaptation, allowing us to change the schema and…
