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 implementation part of the product was easy."
"It directly provides robust data safety. It also offers various other storage options, such as Google Cloud Storage. These services ensure data security and redundancy. Furthermore, it includes different storage classes, allowing flexible data management tailored to specific needs."
"Google Cloud SQL is easy to start with and allows me to scale as needed, which is advantageous from a developer perspective."
"Google Cloud SQL is highly scalable."
"The initial setup is straightforward."
"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."
"MongoDB Atlas is a database that is quite fast, stable, and reliable."
"You can start quickly on projects which allow you to store many things."
"The key feature of MongoDB Atlas that has been helpful for us is the ease of deploying new databases."
"The initial setup is straightforward."
"It's a very elastic solution for the purposes of our systems and the developers appreciate it for software development."
"Its most valuable features are high availability and zero maintenance."
"MongoDB Atlas was explicitly designed to support IoT applications. Many databases offer features tailored for IoT use cases."
"It's flexible. We don't need to have a solid upstream availability failover, and everything is seamless in Atlas."
 

Cons

"Google Cloud SQL needs to improve its support for high-end I/O operations."
"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."
"I would appreciate more flexibility with specific extensions applicable to engines like PostgreSQL. This would enhance the capabilities of Google Cloud SQL."
"The customer support should be improved."
"I would like to see better availability of the product in different regions. It should also improve the security with encryption."
"When discussing media files, such as images and audio files, stored in Google Cloud, concerns about handling large amounts of data arise."
"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."
"Going forward, we would like to have pure AWS Cloud (native) storage instead regular storage on the AWS integration side."
"The UI application for MongoDB crashes a lot, so we would have to use a third-party plugin to make it work."
"If it could be cheaper, that would make us happy."
"The initial setup is not too difficult but can be somewhat tricky."
"The product's file storage documentation needs improvement."
"MongoDB Atlas should support containerization."
"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."
"The web console isn't very intuitive, especially for large data."
 

Pricing and Cost Advice

"From a financial perspective, Google Cloud SQL is on the cheaper side."
"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 solution is affordable."
"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 acceptable for enterprise tier."
"I have seen the cost, and it was pretty cheap."
"The price of MongoDB Atlas is highly affordable."
"We pay for the license on a monthly basis. It's not cheap or expensive. For smaller companies, it's definitely expensive."
"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."
"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."
"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."
"I am using the free version of the solution."
