Has simplified backend development for moderate user applications and supports efficient real-time data updates
A simplified way of building a logical layer on top of Firebase is necessary. Currently, the only option is to use cloud functions or Cloud Run functions. If they come up with an easier way of handling the logical layer between the frontend and backend, that would be beneficial. The UI of Firebase is much better compared to AWS or other Azure, but there is still scope for improving the usability of the UI. Additionally, some more AI features for automation can be added. The security layer can be enhanced, as currently, for data handling, there is just rule-based security; they can add one more layer of data security.

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.

Quotes from Members

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

Pros

"The most valuable features are Firestore's query capabilities and its real-time syncing functionality."
"I use the solution for maps, saving some locations, and chats."
"One of the main features of Google Cloud Firestore's document management is the real-time listener; whenever there are any changes in the data, all the documents and applications that are reading through that particular document get automatically notified that there was some change, and automatically all the data gets refreshed."
"I rate MongoDB Atlas a nine out of ten."
"MongoDB Atlas was explicitly designed to support IoT applications. Many databases offer features tailored for IoT use cases."
"It is a great product."
"The product allows us to easily set up and store large amounts of unstructured data."
"I find MongoDB Atlas highly scalable and easy to use, with very good support."
"The integration and configuration of this product in our AWS environment were easy and straightforward."
"Scalability is its most valuable feature, as it is pretty simple."
"The product provides quick transaction service, high availability, and efficient scalability features."
 

Cons

"Firestore needs improvements in its querying capabilities, particularly the ability to join tables and merge data from different tables before sending it to the front end."
"For lower volumes, it works fine, but once the volume increases, for use cases where the total number of users is less than 100,000 a month, Firebase is cheaper. But once you go beyond that, it becomes very expensive."
"I initially faced a problem creating groups in individual chats."
"We need improved query performance."
"The replica side, like the venue, can be improved."
"I would like a better dashboard. It could be made a bit more user friendly."
"I am not an expert on what improvements could be made to MongoDB."
"Searching and browsing through the collection must be made easier."
"The UI can be difficult to understand."
"The UI application for MongoDB crashes a lot, so we would have to use a third-party plugin to make it work."
"The product does not have ORM."
 

Pricing and Cost Advice

Information not available
"The solution is expensive overall. It does not require a license but if you want the support then you will need to purchase the license. They use a pay-as-you-go model and you are able to receive some discounts by making longer usage commitments."
"The tool is free since it's an open-source product."
"The pricing is acceptable for enterprise tier."
"In my previous company, the product allowed use to build a database in a highly regulated environment with the ability to get distributed storage. We used MongoDB as a distributed storage to set up this environment for a critical business application with millions of dollars."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"The solution is fairly priced."
"Comparing the price between the MongoDB and Microsoft SQL Server, we are using the enterprise edition of Microsoft SQL Server, which is more expensive than MongoDB."
"We pay for the license on a monthly basis. It's not cheap or expensive. For smaller companies, it's definitely expensive."
