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…

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

"The setup was straightforward. Just a couple of clicks, and we were done."
"It runs really well, it's cheap, it's efficient, it's user-friendly."
"Google Cloud SQL enhances our AI-driven projects by providing features like query optimization and scalability for efficiently processing large datasets."
"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 without a lot of infrastructure changes, so I can run a release model experiment on a thousand people and, if that experiment is a success, run it on a million people without any changes while keeping it much more cost-sensitive for me to do it."
"They have good multi-region failure support, and we can just set up there and read replicas directly and we can fall back."
"Ease of management and the ability to oversee the statistics of your SQL."
"Google Cloud SQL is very easy to use and easy to set up; it brings the benefits of being simple to perform queries, store data that I needed to store, and extract data when I needed to extract it quite quickly, without having to set up a full database and queries around it."
"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."
"It is better than the legacy databases, and it is very good with the cloud."
"It can store data as a flat file, similar to a file system."
"MongoDB Atlas was explicitly designed to support IoT applications. Many databases offer features tailored for IoT use cases."
"The cloud-based nature of this solution makes it flexible and scalable, and I like the fact that you can make the deployment bigger as needed, not having to maintain it yourself."
"The dynamic structures are the most valuable."
"It is a solid product, very sustainable, and it takes minimal effort to solve a problem while being very easy to deploy."
"The product allows us to easily set up and store large amounts of unstructured data."
"I would recommend MongoDB Atlas for those who want to start using it."
 

Cons

"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."
"In the case of Google, they need to work on a more easy interface for users."
"They could improve documentation and dashboard stability for efficient user experience and database management."
"I would like to see better integration with all the different tools on the platform."
"The monitoring part could be better."
"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 needs to improve its support for high-end I/O operations."
"Sometimes the sharing with third parties or configuring that in Google Cloud SQL is not the most intuitive."
"The initial configuration fine-tuning for performance can be time-consuming."
"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 cost needs improvement."
"The cost needs improvement."
"We need improved query performance."
"I am not an expert on what improvements could be made to MongoDB."
"The cost needs improvement. The product is good, but the cost that we paid for it is expensive, so it wasn't that valuable."
"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."
 

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."
"It is not expensive, especially considering the significant reduction in database management time."
"You need to pay extra costs for backup and replication."
"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."
"From a financial perspective, Google Cloud SQL is on the cheaper side."
"The pricing is very much an important factor as to why we use this solution."
"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."
"MongoDB Atlas is not expensive, and since it's a cloud-based solution, you pay by usage."
"We pay for a license."
"For me, MongoDB is expensive, but I think it is not so expensive for customers."
"I am using the free version of the solution."
"The pricing is acceptable for enterprise tier."
"For our service, it was around 300 to 600 euros per month, which was acceptable for our customers."
"The purchasing process through the AWS Marketplace was very good."
