Sentiment score
5.0
Users report varied ROI from MongoDB Enterprise Advanced, with some benefiting and others finding measurement difficult, considering alternatives.
Getting an MVP of that project would have taken six to eight months, but because we had an active choice of using Azure Cosmos DB and other related cloud-native services of Azure, we were able to get to an MVP stage in a matter of weeks, which is six weeks.

While solutions for other databases like SQL or PostgreSQL already exist, MongoDB requires additional integrations for developing AI solutions.
Head Of Data Science 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.
Cloud Architect at a computer software company with 1,001-5,000 employees
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

Microsoft Azure Cosmos DB offers scalable, responsive, pay-as-you-go pricing with auto-scaling features but can have unpredictable costs.
MongoDB Enterprise Advanced offers cost-effective pricing with various editions and support, valued by small businesses for enterprise transition.
Initially, it seemed like an expensive way to manage a NoSQL data store, but so many improvements that have been made to the platform have made it cost-effective.
Lead Cloud Architect at Solliance, Inc
Cosmos DB is expensive, and the RU-based pricing model is confusing.
IT Data Architect & Manager at Ternium Mexico S.A. de C.V.
Cosmos DB is great compared to other databases because we can reduce the cost while doing the same things.
Lead Software Architect at CPower
We use the free version of MongoDB, so there are no licensing costs.
Head Of Data Science at Mjunction Services
We have to pay approximately 2,000 euros per month for MongoDB.
Cloud Architect at a computer software company with 1,001-5,000 employees
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.

Technical Manager at Infosys
Real-time messaging has transformed customer updates and now powers responsive AI experiences
The primary benefits of Microsoft Azure Cosmos DB include horizontal scalability. The main advantage is that it handles data growth without requiring database redesign when traffic increases. Low latency access is another key benefit, as read and write operations are very fast, which is extremely helpful for real-time applications. Flexibility is also valuable because Microsoft Azure Cosmos DB uses JSON schema format, which contrasts with traditional table schemas that require time-consuming changes. In modernization scenarios where client requirements change rapidly, Microsoft Azure Cosmos DB offers more flexible schema design. High availability is another important feature, as it is well-suited for business-critical systems. My overall experience using Microsoft Azure Cosmos DB with other Azure services shows that it is more flexible compared to SQL Database and more readable because of its JSON format, making it easy to understand. It is more interactive because viewing the Microsoft Azure Cosmos DB schema clearly shows what is happening in the application and what will be achieved. In contrast, SQL requires writing many queries to obtain details, making Microsoft Azure Cosmos DB more suitable and flexible. My team's experience developing with Microsoft Azure Cosmos DB SDKs and APIs has been very comfortable and easy to implement. We are currently migrating .NET applications to Python-based AI solutions using Copilot, where we performed reverse engineering and are moving to forward engineering. We use APIs to connect with Microsoft Azure Cosmos DB and manage database containers and items, performing CRUD operations such as create, delete, and read operations, and querying JSON. We are using REST APIs with Python-based solutions, with a service layer and Microsoft Azure Cosmos DB integration.

Document data has streamlined prototyping and now supports secure cloud deployments
I use the cloud version of the product. MongoDB Enterprise Advanced is from MongoDB, though I also use DigitalOcean as a third-party provider. Maybe it's all more about preferences. I think MongoDB Enterprise Advanced has weak support on the ORM side, particularly if you're using Prisma. I think mostly the focus now on the tools we have is PostgreSQL. MongoDB Enterprise Advanced is not really used that much on our side for production. It's not really a weak point. It's more of a double-edged sword. If you like document-based management databases and you don't want any migrations, then you go to MongoDB Enterprise Advanced. If you want more secure databases, then you use SQL. On the account management and the way you secure the connection strings, I have utilized advanced security features with MongoDB Enterprise Advanced. I think it's very expensive on the Atlas enterprise side. But if you go to other providers of MongoDB Enterprise Advanced, such as DigitalOcean, it may be harder to set up, but they can save you money.
