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

"This is a stable solution and offers good performance."
"The product is scalable."
"The setup was straightforward. Just a couple of clicks, and we were done."
"From a database management perspective, it provides services without the need for me to worry about backups, scaling, or other operational issues."
"Google Cloud SQL is easy to start with and allows me to scale as needed, which is advantageous from a developer perspective."
"It is not the cool features that I find valuable, it is the stability of Google Cloud Platform."
"The initial setup is straightforward."
"It's SQL. SQL is so easy if you know something about databases. It's easy to learn."
"As a tester, it was easy to validate data, access data, make active run queries against it, and retrieve data from it."
"You can start quickly on projects which allow you to store many things."
"The speed of it is the most valuable feature."
"The solution is easy to use, the console is user-friendly, and overall a well-designed solution. It takes a complex system and makes it easy to understand. Additionally, the solution is always advancing and they provide a roadmap into what is coming in the future."
"Object-based data storing capability and managing non-structured data capability are the most valuable features of MongoDB Atlas."
"What I found most valuable in MongoDB Atlas is its Elasticsearch feature. It also has high availability, so it's stable."
"The product is simple to use and enterprise-ready. It is also open-source."
"The solution is easily scalable and manageable. Tools can be easily added to the solution."
 

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."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL. This would enhance the capabilities of Google Cloud SQL."
"For data analysis, the AI area of the product has certain shortcomings where improvements are required."
"The product's user interface could be more user-friendly to improve the overall user experience."
"In the case of Google, they need to work on a more easy interface for users."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL."
"The only thing that could be better is the pricing."
"Google Cloud SQL still needs better connectivity to outside, existing data sources."
"The price of the solution should be reduced."
"MongoDB Atlas should support containerization."
"When I edit a document from a document, a lot of clicking is involved, like changing data type manually from a drop-down. It would be super nice if I could just edit the document in a JSON format. The JSON-based document editor should have a multi-language feature. Also, it would be great if there was a connect option from Google Looker Studio."
"I would say pricing is an area where MongoDB Atlas could improve."
"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."
"I would like a better dashboard. It could be made a bit more user friendly."
"The initial setup is not too difficult but can be somewhat tricky."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
 

Pricing and Cost Advice

"The solution is affordable."
"It's really cheap. It wouldn't be more than, I believe it's around 50 euro per month for running a cloud SQL."
"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."
"While the platform’s pricing may be higher, it aligns with industry standards, considering the quality of service and features provided."
"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 not that expensive, but it can be, especially when we have deployed it across multiple zones."
"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."
"I am using the free version of the solution."
"The solution is fairly priced."
"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."
"We pay for a license."
"The tool is free since it's an open-source product."
"For me, MongoDB is expensive, but I think it is not so expensive for customers."
