Multi-node architecture and it is good from a security point of view

I would rate the stability a seven out of ten. Most of the issues we faced during troubleshooting were due to specific bugs in the environment, and the only solution was to upgrade the database environment or services. But it is not easy to upgrade the database level when third-party applications are involved, as they are not always comfortable with upgrading. There should be some cumulative solution provided by IBM for their customers, just like other vendors. Upgrading to a certain version doesn't always resolve the issue. It might get resolved at the database level, but what about the other applications integrated with that database that are only compatible with older versions?

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:

"The speed of it is the most valuable feature."

"It has a flexible integration with our easy API."

"This solution is very helpful due to its ease of use."

"The key feature of MongoDB Atlas that has been helpful for us is the ease of deploying new databases."

Cons

"In other environments like Oracle or Teradata, they provide their own solutions for troubleshooting issues. They provide built-in AI services or autonomous databases, which I don't see in the Db2 environment."

"I would give their support a ten if they had more tutorials available."

"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."

"I would like the solution to offer more integration capabilities since it is an area where the solution lacks."

"Based on its own habitat, it's not ACID compliant. If it had an ACID compliant option, it would be more useful for database administration."

"That is the only drawback that I find with MongoDB: creating the trigger."

"I am not an expert on what improvements could be made to MongoDB."

"Searching and browsing through the collection must be made easier."

"MongoDB Atlas should improve its user experience by providing better explanations or a wizard for people working with its UI."

"One improvement that I would like to see is a feature to export changes made in the environment, such as creating a new user."
