Gain control and flexibility with customizable tools but has slower performance

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

"It supports different databases, like Postgres and MySQL."
"It is not the cool features that I find valuable, it is the stability of Google Cloud Platform."
"Google Cloud SQL is very easy to use and easy to set up; it brings the benefits of being simple to perform queries, store data that I needed to store, and extract data when I needed to extract it quite quickly, without having to set up a full database and queries around it."
"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 significant control and flexibility."
"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."
"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."
"What I like the most about Google Cloud SQL is that it handles the management, which allows us to concentrate on our applications."
"This solution is very helpful due to its ease of use."
"Being schemaless is what I like best about MongoDB Atlas."
"Our databases used to be in-house. Now, they are in the cloud with MongoDB and everything is much easier."
"I am impressed with the tool's integrations."
"The most valuable feature of MongoDB Atlas is it's seamless when working with a lot of different systems. Additionally, it is able to adjust the data based on the data being received."
"As a tester, it was easy to validate data, access data, make active run queries against it, and retrieve data from it."
"For security reasons, I prefer MongoDB Atlas. It supports role-based access control, so you have an entity for each individual."
"The initial setup is straightforward."
 

Cons

"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."
"The overall documentation and the connectors need improvement."
"In the case of Google, they need to work on a more easy interface for users."
"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."
"Google Cloud SQL needs to improve its support for high-end I/O operations."
"The only thing that could be better is the pricing."
"They could improve documentation and dashboard stability for efficient user experience and database management."
"The performance compared to AWS is not as fast, and the technical support could be better as they don't have a dedicated team, but mostly AI handles the support now."
"I would say pricing is an area where MongoDB Atlas could improve."
"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."
"That is the only drawback that I find with MongoDB: creating the trigger."
"The web console isn't very intuitive, especially for large data."
"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."
"I am still new with it, but since I mentioned that I'm using this product for only the last six months and my experience with this product is good thus far, on a scale of one to ten, I would give MongoDB Atlas a six."
"The UI application for MongoDB crashes a lot, so we would have to use a third-party plugin to make it work."
"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."
 

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."
"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."
"You need to pay extra costs for backup and replication."
"The pricing is very much an important factor as to why we use this solution."
"MongoDB Atlas is not expensive, and since it's a cloud-based solution, you pay by usage."
"The solution is fairly priced."
"For our service, it was around 300 to 600 euros per month, which was acceptable for our customers."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"We pay for a license."
"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 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."
