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

"The valuable feature of Google Cloud SQL is its high availability option. The product is stable."
"The deployment model allows for significant control and flexibility."
"The implementation part of the product was easy."
"The most valuable features are that it's easy to use, simple, and user-friendly."
"It supports different databases, like Postgres and MySQL."
"I found its storage and security to be the most valuable. It was a good experience. It is also very stable and scalable, and its support is perfect."
"Google Cloud SQL is easy to start with and allows me to scale as needed, which is advantageous from a developer perspective."
"Ease of management and the ability to oversee the statistics of your SQL."
"The key feature of MongoDB Atlas that has been helpful for us is the ease of deploying new databases."
"You can start quickly on projects which allow you to store many things."
"The most beneficial MongoDB features for our workload are the ability to scale up and down using automatic sharding and clustering."
"Its most valuable features are high availability and zero maintenance."
"It has a flexible integration with our easy API."
"Scalability is its most valuable feature, as it is pretty simple."
"The dynamic structures are the most valuable."
"Our databases used to be in-house. Now, they are in the cloud with MongoDB and everything is much easier."
 

Cons

"The overall documentation and the connectors need improvement."
"Google Cloud SQL needs to improve its support for high-end I/O operations."
"The monitoring part could be better."
"I am yet to explore a lot of features that are present in this solution. However, it would be good if more documentation is available for this solution. This would help us in preparing for the certification exam and understand it better. Currently, we don't have much documentation. We do the labs for 20 or 25 minutes, but we can't capture and download anything."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL."
"In the case of Google, they need to work on a more easy interface for users."
"I would like to see better integration with all the different tools on the platform."
"They could improve documentation and dashboard stability for efficient user experience and database management."
"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."
"The cost needs improvement."
"That is the only drawback that I find with MongoDB: creating the trigger."
"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."
"We had some edge cases where scalability was an issue where a node went offline, and we had to deal with that."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
"One improvement that I would like to see is a feature to export changes made in the environment, such as creating a new user."
"The tool's implementation should be made easier."
 

Pricing and Cost Advice

"You need to pay extra costs for backup and replication."
"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."
"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."
"It's really cheap. It wouldn't be more than, I believe it's around 50 euro per month for running a cloud SQL."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"For our service, it was around 300 to 600 euros per month, which was acceptable for our customers."
"The pricing and licensing is great."
"The price of MongoDB Atlas is highly affordable."
"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."
"It is an open-source platform."
"The price of MongoDB Atlas is highly expensive to use and maintain. They are taking advantage of the users with such a high price."
"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."
