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.

"It's a very elastic solution for the purposes of our systems and the developers appreciate it for software development."
 

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."
"To create a seamless data integration, the title integration of these databases with the data integration platforms is essential. This is what we would like to have in a future release."
"The monitoring part could be better."
"The customer support should be improved."
"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."

"Google Cloud SQL needs to improve its support for high-end I/O operations."
"The cost needs improvement."
"I am not an expert on what improvements could be made to MongoDB."
"The biggest challenge we all have is an application layer level. One node is sitting in the APAC region, another node is sitting in the US and UK region. The seamless replication has to be lightning fast, but we haven't tested the scalability yet."
"I would like a more comprehensive dashboard."
"I would like to have better performance for user experience with the solution."
"They could explore ways to facilitate deploying MongoDB containers within the platform."
"In the past, MongoDB offered more features for free, but now it's quite limited. The free version is limited, and you need to pay extra to fully utilize it. The pricing could be improved."
"An area for improvement in MongoDB Atlas is that it does not support individual or personal database backup, though it supports cloud cluster backup."

"Pricing could always be better."
"It is an open-source platform."
"The purchasing process through the AWS Marketplace was very good."
"The pricing is good. We originally chose it over DynamoDB because of the pricing."
