engagement Manager at Capgemini
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.

IT Manager at a government with 11-50 employees
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

"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."
"The most valuable features are Firestore's query capabilities and its real-time syncing functionality."
"This solution is very helpful due to its ease of use."
"My company is interested in putting out products that are reliable for our customers, which we can monitor easily, and we also want them to be easy to install and deploy, which is why I am happy with this one."
"The most beneficial MongoDB features for our workload are the ability to scale up and down using automatic sharding and clustering."
"The auto-scaling feature is the most valuable aspect."
"The key feature of MongoDB Atlas that has been helpful for us is the ease of deploying new databases."
"The product provides quick transaction service, high availability, and efficient scalability features."
"The initial setup is straightforward."
"It's a very elastic solution for the purposes of our systems and the developers appreciate it for software development."
 

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."
"Going forward, we would like to have pure AWS Cloud (native) storage instead regular storage on the AWS integration side."
"MongoDB Atlas should add more APIs in their Terraform module because sometimes I find it difficult to find the resources in their Terraform model."
"The installation was straightforward except for the network hardware because it was a little complicated to make the connection with our VPC on AWS."
"The product's data aggregation feature needs to work faster."
"I would like to have better performance for user experience with the solution."
"The initial setup is not too difficult but can be somewhat tricky."
"The product's file storage documentation needs improvement."
 

Pricing and Cost Advice

Information not available
"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."
"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 solution is fairly priced."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"The pricing and licensing is great."
"It is too expensive. They need to work on this."
"We're currently using the Atlas for the night and don't require a license. However, it can be a problem if you want to use their enterprise environment. Then you need to purchase the license."
"I have seen the cost, and it was pretty cheap."
