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…

Room for improvement in data handling leads to enhanced cost-effective data management performance
It would be beneficial if MongoDB Atlas could better support OLTP aspects and data frames, as well as enhance its capabilities for data pipelines and visualization dashboards. Furthermore, supporting the medallion architecture could be a valuable addition, and incorporating improved spatial and vector handling for geographical data could make it more competitive. Enhancing vector processing for AI capabilities would also be critical.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"From a database management perspective, it provides services without the need for me to worry about backups, scaling, or other operational issues."
"The most valuable features are that it's easy to use, simple, and user-friendly."
"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."
"The product is scalable."
"It runs really well, it's cheap, it's efficient, it's user-friendly."
"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 supports different databases, like Postgres and MySQL."
"The main benefit to our organization is the fact that we no longer need DB admins that take care of the physical servers, backups etc... All this is managed by GCP."
"The solution is easily scalable and manageable. Tools can be easily added to the solution."
"It supports many functionalities, is easier to implement, and the only issue is speed."
"The dynamic structures are the most valuable."
"The product provides quick transaction service, high availability, and efficient scalability features."
"The product is simple to use and enterprise-ready. It is also open-source."
"MongoDB Atlas was explicitly designed to support IoT applications. Many databases offer features tailored for IoT use cases."
"Being schemaless is what I like best about MongoDB Atlas."
"It is a great product."
 

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."
"The most challenging part is dealing with legacy data from your old systems and migrating it into the new setup, but once you've completed the data migration, it becomes quite convenient to use."
"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."
"For write operations – yes, as there is no MySQL clustering mode."
"In the case of Google, they need to work on a more easy interface for users."
"Google Cloud SQL needs to improve its support for high-end I/O operations."
"In my opinion the most vulnerable problem with Google SQL is each SQL node is provided with a public IP address."
"When discussing media files, such as images and audio files, stored in Google Cloud, concerns about handling large amounts of data arise."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
"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 cost needs improvement. The product is good, but the cost that we paid for it is expensive, so it wasn't that valuable."
"Querying a dataset is not very intuitive, so I think that it can be improved."
"I would like a better dashboard. It could be made a bit more user friendly."
"The product's data aggregation feature needs to work faster."
"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."
"One improvement that I would like to see is a feature to export changes made in the environment, such as creating a new user."
 

Pricing and Cost Advice

"From a financial perspective, Google Cloud SQL is on the cheaper side."
"The solution is affordable."
"The pricing is very much an important factor as to why we use this solution."
"You need to pay extra costs for backup and replication."
"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."
"While the platform’s pricing may be higher, it aligns with industry standards, considering the quality of service and features provided."
"The solution is fairly priced."
"The price of MongoDB Atlas is highly affordable."
"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."
"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."
"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."
"It is too expensive. They need to work on this."
"The tool is free since it's an open-source product."
