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

"I use the solution for maps, saving some locations, and chats."
"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."
"MongoDB Atlas is a database that is quite fast, stable, and reliable."
"What I found most valuable in MongoDB Atlas is its Elasticsearch feature. It also has high availability, so it's stable."
"The product is user-friendly."
"I would recommend MongoDB Atlas for those who want to start using it."
"In my previous company, the product allowed us to build a database in a highly regulated environment with the ability to get distributed storage, and we used MongoDB as a distributed storage to set up this environment for a critical business application with millions of dollars."
"The product is simple to use and enterprise-ready. It is also open-source."
"The speed of it is the most valuable feature."
"It can store data as a flat file, similar to a file system."
 

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."
"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."
"If it could be cheaper, that would make us happy."
"The speed when combining two documents is concerning."
"During the configuration, we did some migrations where we had to reindex about 70,000 indexes, which took around an hour. They should improve this and optimize the indexing."
"There are some features that could be useful for the customers I work with, which are related to migration from on-prem to the cloud."
"From an improvement standpoint, MongoDB can improve security."
"The price of the solution should be reduced."
"Searching and browsing through the collection must be made easier."
"MongoDB Atlas should add more APIs in their Terraform module because sometimes I find it difficult to find the resources in their Terraform model."
 

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 pricing is good. We originally chose it over DynamoDB because of the pricing."
"The pricing is acceptable for enterprise tier."
"The solution is fairly priced."
"The price of MongoDB Atlas is highly expensive to use and maintain. They are taking advantage of the users with such a high price."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"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."
