It has visible benefits, actually, in terms of price of ownership if you compare it to, for example, Oracle.

We can define security rules at the database level or the cluster level to grant or deny access to particular users.

The solution's most important aspect is its seamless database.

Scalability seems good. I've never been even close to finding the limits. I've run a couple of notes of redundancy but I've never had any problems with scalability.

The initial setup isn't really that complex.

It is a stable solution. Stability-wise, I rate the solution a nine out of ten...Overall, MongoDB has helped manage and analyze attachment data.

I like that MongoDB has a free version. You can also buy the enterprise edition, which is cheaper than Oracle.

MongoDB has definitely helped us improve our network monitoring and reporting dashboard, so I would say it has impacted our operations positively overall.

We'd like information about client onboarding experience and success stories. It would help to have something to show to internal stakeholders.

Data encryption is possible using third-party tools but they should have their own encryption capability built-in to this solution.

MongoDB should not be used for reporting, analytics, or number-crunching tasks.

The on-premises version of the solution is still pretty expensive, especially compared to the cloud version.

More stable indexes would be helpful in a future release. That's been an issue for some time. I don't know if it's been fixed now but we transitioned to it because we needed a search index to be able to search for things and if that goes or starts disappearing, we have to move away from that solution. I don't know if they fixed it, last time I had this issue was three years ago so they might have solved it.

MongoDB should better support small and medium companies. There are a lot of clients out there that are interested, however, they need something lighter and less complex and something not so expensive upfront.

It is important to note that MongoDB has limitations since it can only be used for specific use cases. For example, for master data, I would want to pick keys using an RDBMS, but for attachments, I would choose MongoDB.

I don't see a lot of areas that need improvement.

It could be more stable. It would be better if it were more user-friendly like Oracle, which is very easy. For example, creating an index is simple in Oracle. In MongoDB, it's quite challenging to do that. Performance could be better. It's fast and good, but you cannot put every application that you would like to in MongoDB.

I would recommend MongoDB as part of a template if anyone is considering free and open-source templating services such as LibreNMS, but as a standalone, I couldn't advise.
