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.
Varuns Ug - PeerSpot reviewer

Flexible document workflows have accelerated schema changes and simplified evolving data models
MongoDB Atlas currently has almost all the features we require, but there are some points where I see certain improvements. One area is cost visibility and optimization. Since pricing is largely based on storage and cluster size, it can sometimes be difficult to predict or optimize cost without deeper insights. More granular cost breakdowns or recommendations would be helpful. Another area I can mention is performance tuning transparency. While MongoDB Atlas provides monitoring and suggestions, debugging deeper issues like slow queries, index efficiency, or shard imbalance can sometimes require more control or visibility. Cost optimization, deeper performance insight, and easier scaling decisions would make MongoDB Atlas even more powerful. A couple of additional areas where MongoDB Atlas could improve are integrations and developer experience. For integrations, while MongoDB Atlas supports major cloud providers and tools, deeper and more seamless integration with observability patterns would make troubleshooting distributed systems easier. On the documentation side, while it is generally good, some advanced topics like sharding strategies, performance tuning, and real-world scaling patterns could benefit from more practical guidance. Additionally, a better local-to-cloud development experience, making it easier to replicate production-like MongoDB Atlas environments locally, would help developers test performance and scaling scenarios more efficiently.

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."
"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 use the solution for maps, saving some locations, and chats."
"It is better than the legacy databases, and it is very good with the cloud."
"It is nice because our developers create tables whenever they need to sync data."
"It enables us to get work done quickly and get to our data."
"The stability and performance are great. The high availability feature is great. Moreover, I am happy with the automated backup and restore functionality."
"MongoDB Atlas is our primary database, and we prefer this because of the reliability of MongoDB Atlas."
"The scalability is very high, the performance is very high, and the cost is lower as compared to the traditional database for cloud."
"As a tester, it was easy to validate data, access data, make active run queries against it, and retrieve data from it."
"It can store data as a flat file, similar to a file system."
 

Cons

"I initially faced a problem creating groups in individual chats."
"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."
"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."
"From the scalability point of view, when we shard the database it creates a replica set of each shard and that will increase the cost."
"The UI is not currently designed in a manner to make it possible for a non-technical person or a layman to update the database easily."
"The product's data aggregation feature needs to work faster."
"Going forward, we would like to have pure AWS Cloud (native) storage instead regular storage on the AWS integration side."
"I am not an expert on what improvements could be made to MongoDB."
"I would like to have better performance for user experience with the solution."
"The speed when combining two documents is concerning."
"I would like a better dashboard. It could be made a bit more user friendly."
 

Pricing and Cost Advice

Information not available
"Pricing could always be better."
"The price of MongoDB Atlas is highly affordable."
"We pay for the license on a monthly basis. It's not cheap or expensive. For smaller companies, it's definitely expensive."
"MongoDB Atlas is more cost-effective than Amazon DocumentDB. It also has a pay-as-you-go pricing model. Apart from the standard licensing cost, you must also pay to get MongoDB Atlas technical support, which is expensive."
"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."
"It is an open-source platform."
"I have seen the cost, and it was pretty cheap."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
