Prathap Sankar - PeerSpot reviewer
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

"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."
"Ease of management and the ability to oversee the statistics of your SQL."
"It supports different databases, like Postgres and MySQL."
"The most valuable feature for us is the Postgres on Google Cloud SQL since it supports most of the features we need."
"It is not the cool features that I find valuable, it is the stability of Google Cloud Platform."
"The product is scalable."
"The most valuable features are that it's easy to use, simple, and user-friendly."
"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 product allows us to easily set up and store large amounts of unstructured data."
"The most useful feature is the management of the backup."
"There are many valuable features, but scalability stands out. It can scale across zones. You can define multiple nodes. They have also partnered with AWS, offering great service with multiple features, including built-in backup, all under the same roof, without the need for external tools."
"It's flexible. We don't need to have a solid upstream availability failover, and everything is seamless in Atlas."
"It is a scalable solution because we use quite a lot of data, and it handles it well."
"The product provides quick transaction service, high availability, and efficient scalability features."
"The auto-scaling feature is the most valuable aspect."
"I am impressed with the tool's integrations."
 

Cons

"The product's user interface could be more user-friendly to improve the overall user experience."
"The most vulnerable problem with Google SQL is that while you can customize your access control list, it provides you with a public IP address."
"They could improve documentation and dashboard stability for efficient user experience and database management."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL. This would enhance the capabilities of Google Cloud SQL."
"The overall documentation and the connectors need improvement."
"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."
"When discussing media files, such as images and audio files, stored in Google Cloud, concerns about handling large amounts of data arise."
"MongoDB Atlas should add more APIs in their Terraform module because sometimes I find it difficult to find the resources in their Terraform model."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
"I am not an expert on what improvements could be made to MongoDB."
"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."
"An area for improvement in MongoDB Atlas is that it does not support individual or personal database backup, though it supports cloud cluster backup."
"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."
"A few areas that we have noticed as being problematic with the MongoDB Atlas include user access to the platform. Currently, it is difficult to restrict and control what actions a user can perform within the solution, which poses a challenge from an internal auditing perspective."
"If it could be cheaper, that would make us happy."
 

Pricing and Cost Advice

"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."
"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."
"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."
"From a financial perspective, Google Cloud SQL is on the cheaper side."
"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."
"MongoDB Atlas is not expensive, and since it's a cloud-based solution, you pay by usage."
"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."
"Pricing could always be better."
"We pay for a license."
"The price of MongoDB Atlas is highly affordable."
"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."
"The purchasing process through the AWS Marketplace was very good."
