Gain control and flexibility with customizable tools but has slower performance
I am majorly working in Google Cloud SQL for building my applications Google Cloud SQL provides complete customization options, along with a dashboarding tool and a comprehensive suite of tools that can be used to customize and build any application needed. The deployment model allows for…

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 speed is very good, it's useful in terms of the simplicity of doing backups, you can have redundant databases for reports or posts, it's SQL which is easy to learn if you know something about databases, I like the cloud aspect, the pricing of the solution seems reasonable, and the solution is stable."
"Its most valuable feature is that it's scalable. I can start off with a base of a lot of data and move as much as I want and it's the same as if asked to do a lot of infrastructure changes."
"They have good multi-region failure support, and we can just set up there and read replicas directly and we can fall back."
"The solution is easy to use. I am impressed with the tool's features and functionality."
"It's SQL. SQL is so easy if you know something about databases. It's easy to learn."
"My suggestion to anyone thinking about this solution is to jump into it head-first!"
"The implementation part of the product was easy."
"Google Cloud SQL is highly scalable."
"The most valuable feature is the schemaless architecture."
"I find MongoDB Atlas highly scalable and easy to use, with very good support."
"Scalability is its most valuable feature, as it is pretty simple."
"It is nice because our developers create tables whenever they need to sync data."
"It's a very elastic solution for the purposes of our systems and the developers appreciate it for software development."
"MongoDB Atlas was explicitly designed to support IoT applications. Many databases offer features tailored for IoT use cases."
"It has a flexible integration with our easy API."
"I would recommend MongoDB Atlas to potential users."
 

Cons

"The only room for improvement here is that they need to connect to more existing data sources so that it becomes easier for a layman to get a more realistic understanding of what's happening."
"I am yet to explore a lot of features that are present in this solution. However, it would be good if more documentation is available for this solution."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL."
"To create a seamless data integration, the title integration of these databases with the data integration platforms is essential."
"Google's technical support is good, but they tend to never reopen a case and to send us snippets from the publicly available documentation. It's not as helpful as you would expect, not just for Google Cloud SQL but for all of Google Cloud products."
"Google Cloud SQL still needs better connectivity to outside, existing data sources."
"The only thing that could be better is the pricing."
"For data analysis, the AI area of the product has certain shortcomings where improvements are required."
"The speed when combining two documents is concerning."
"One improvement that I would like to see is a feature to export changes made in the environment, such as creating a new user."
"The cost needs improvement. The product is good, but the cost that we paid for it is expensive, so it wasn't that valuable."
"The import and export process needs improvement, i.e., getting in and out. Moving data from other databases into MongoDB, along with indexing, was challenging."
"I would like the solution to offer more integration capabilities since it is an area where the solution lacks."
"It would be better if there were more integration capabilities with other products."
"The price of the solution should be reduced."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
 

Pricing and Cost Advice

"It's really cheap. It wouldn't be more than, I believe it's around 50 euro per month for running a cloud SQL."
"While the platform’s pricing may be higher, it aligns with industry standards, considering the quality of service and features provided."
"The solution is affordable."
"You need to pay extra costs for backup and replication."
"It is not expensive, especially considering the significant reduction in database management time."
"The pricing is very much an important factor as to why we use this solution."
"From a financial perspective, Google Cloud SQL is on the cheaper side."
"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."
"We pay for the license on a monthly basis. It's not cheap or expensive. For smaller companies, it's definitely 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."
"For our service, it was around 300 to 600 euros per month, which was acceptable for our customers."
"The solution is fairly priced. I rate the pricing a seven out of ten."
"I have seen the cost, and it was pretty cheap."
"The price of MongoDB Atlas is highly expensive to use and maintain. They are taking advantage of the users with such a high price."
"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."
