ROI from MongoDB Enterprise Advanced varies significantly; some see gains, others don't, with the community version as a cheaper alternative.
It offers at least 25 percent cost savings compared to maintaining on-premises databases.
Principle azure architect at Intercept
Now, we use embedded PostgreSQL vectors, which will undoubtedly reduce the TCO by using a much more cost-effective solution.
Head of cloud, data, and AI at BJSS
We've reduced our total ownership cost because we are not spending on expensive SQL server licenses.
Admin (hands on user) at a comms service provider with 11-50 employees
Actually, with MongoDB, it's difficult to calculate the return on investment; it's too expensive for our use.
Architecte Cloud at Visiativ SA
I would say we see value in money and return on investment with MongoDB Enterprise Advanced.

5.4
Azure Database for PostgreSQL support experiences vary, praised for responsiveness but criticized for inconsistency and contentious licensing issues.
Sentiment score
6.2
MongoDB Enterprise Advanced support varies; some praise its responsiveness, while others rely on internal resources or community forums.
Once we open a support case, we have people engaged within about 20 minutes, especially for a Sev 1 issue.
Financial Advisor at a financial services firm with 10,001+ employees
On a scale from one to ten, I rate customer service and technical support a nine because they are quick in responding and in working with me to rectify any issues we come across.
Cloud Engineer at a financial services firm with 10,001+ employees
The documentation and training we've received through Microsoft Learn on how to migrate, deploy, and manage the solution is exceptional.
Head of cloud, data, and AI at BJSS
We have received fairly good support whenever we reached out to the technical teams; they were prompt.
Co-Founder at Vsigma IT Labs Pvt Ltd
 

Scalability Issues

Sentiment score
5.6
Azure Database for PostgreSQL scales efficiently, supporting complex applications with features like FlexServer and recent redundancy and auto-scaling improvements.
Sentiment score
7.6
MongoDB Enterprise Advanced is scalable and flexible for large users, but some face cost and configuration challenges.
We do not have to buy everything and build it. It is already there.
Systems Engineer II at ICW Group
However, we can see how well it scales after we deploy it for some large enterprise customers or big government organizations.
Head of cloud, data, and AI at BJSS
The scaling options with FlexServer provide us with the flexibility we need based on application complexity.
Director, Alliances & Engineering at a computer software company with 1,001-5,000 employees
In CosmoDB, the scalability is much better than with the MongoDB ReplicaSet models.
Architecte Cloud at Visiativ SA
MongoDB is highly scalable.
Head Of Analytics at Mjunction Services
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.
General Manager at Lytwave
 

Stability Issues

Sentiment score
7.2
Azure Database for PostgreSQL is praised for stability, reliable uptime, and Microsoft’s swift resolution of occasional performance issues.
Sentiment score
7.6
MongoDB Enterprise Advanced is stable, reliable, and adaptable, with high ratings despite minor bugs and room for improvement.
It is the go-to database if seeking performance and capacity.
Director at a financial services firm with 10,001+ employees
I have not experienced any downtime, crashes, or performance issues; it has been very stable.
Cloud Engineer at a financial services firm with 10,001+ employees
There is a stability issue where, if the database usage peaks quickly, it may crash and require intervention to restore functionality.
Principle azure architect at Intercept
It's pretty much stable; we have not faced any major challenges or difficulties with MongoDB Enterprise Advanced.
Co-Founder at Vsigma IT Labs Pvt Ltd
 

Room For Improvement

Azure Database for PostgreSQL needs enhancements in scalability, reliability, monitoring, integrations, user management, and disaster recovery features.
MongoDB Enterprise Advanced needs better security, integration, documentation, and scalability, while addressing stability, transactions, and TypeScript support issues.
It does not presently support knowledge graph functionalities as Neo4j does.
Product manager at a financial services firm with 5,001-10,000 employees
Azure Database for PostgreSQL can be improved by allowing quicker scaling without blips.
Principle azure architect at Intercept
I believe there could be improvements in the mirroring part and Change Data Capture (CDC).
Director, Alliances & Engineering at a computer software company with 1,001-5,000 employees
While solutions for other databases like SQL or PostgreSQL already exist, MongoDB requires additional integrations for developing AI solutions.
Head Of Analytics at Mjunction Services
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.
Architecte Cloud at Visiativ SA
From the AWS standpoint, if robust integration and data warehouse integration specific tools are added in the advanced suite, that would definitely be helpful.
Co-Founder at Vsigma IT Labs Pvt Ltd
 

Setup Cost

Azure Database for PostgreSQL offers cost-effective scalability with pay-as-you-go pricing, despite higher costs than on-premises solutions.
MongoDB Enterprise Advanced pricing varies by size, with free Community Edition and budget-friendly cloud options like MongoDB Atlas.
We've reduced costs by 60 percent compared to maintaining on-premises solutions.
Director, Alliances & Engineering at a computer software company with 1,001-5,000 employees
We chose it because it is more cost-effective than Microsoft SQL.
Cloud Solutions Architect at Measurement Incorporated
Once you are comfortable and ready to make some commitments, you get about 30 percent saving if you are going with one-year or three-year reservation cost.
Staff Data Engineer at a transportation company with 10,001+ employees
We use the free version of MongoDB, so there are no licensing costs.
Head Of Analytics at Mjunction Services
We have to pay approximately 2,000 euros per month for MongoDB.
Architecte Cloud at Visiativ SA
For a small company, the cost of MongoDB Enterprise Advanced is reasonable, but for heavy data usage, we see a little bit of cost pressure but it's acceptable.
Co-Founder at Vsigma IT Labs Pvt Ltd
 

Valuable Features

Azure Database for PostgreSQL offers simplicity, performance, security, scalability, and AI integration, enhancing cloud strategy through robust features.
MongoDB Enterprise Advanced excels in scalability, flexibility, NoSQL capabilities, fast performance, and seamless integration, enhancing data management efficiency.
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.
Head of cloud, data, and AI at BJSS
The query analyzers help me find out what's happening in each of the queries.
IT Director at Infosys
If a database has any task that has been interrupted or any connection issue, it will alert LogicMonitor, and we have a centralized panel for all the alerts.
System Engineer II at a insurance company with 501-1,000 employees
It offers flexibility in schema adaptation, allowing us to change the schema and add new data points.
Head Of Analytics at Mjunction Services
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.
Architecte Cloud at Visiativ SA
MongoDB has definitely helped us improve our network monitoring and reporting dashboard.
General Manager at Lytwave

Featured Reviews

Sathish Palanisamy - PeerSpot reviewer
Staff Data Engineer at a transportation company with 10,001+ employees
Improves database performance, supports AI integration, and accelerates customer-focused innovation
Azure Database for PostgreSQL can be improved in the area of elastic capabilities. One of the things we were actively looking for is the elastic feature, which was made a GA at this Ignite event. I am really happy that finally in Azure, we have a product which we can use for elastic clusters. If you are bound with a single server, then you have a vertical limit. Now you do not have any limits. As long as your use case grows, we can grow. The only thing I would maybe be thinking about is we should also allow customers to pick different node sizes for every node inside the elastic eventually. Some nodes do not need that big capacity. So that may be a nice-to-have feature, though it is not a must-have at this point.

Offers reliable engine for legacy needs but requires enhanced cost management and AI features
While MongoDB is a good product, it is also an expensive product for support, and its scalability is acceptable, but the big problem with MongoDB is the cost. For security in MongoDB, we work with encrypted databases by default, but we have not contracted the security options in our contract because it is too expensive, so we only implement encrypted databases without the security pack, which is very expensive for us; in security, we are at the first steps, just using encrypted databases. I think additional features needed in MongoDB include perhaps vector databases, as I think they are not supported right now.
