Back End Developer at Zeta
Multiple graph models and languages support lead to efficient use, yet community growth brings challenges
The onboarding part and documentation where we could ideally use Amazon Neptune is excellent. Amazon Neptune as a product by AWS is exceptional because it supports multiple graph models such as RDF and property graph. It also has support for multiple querying languages such as Gremlin, SparkQL, and OpenCypher. It is very comprehensive in supporting every requirement we had at Zetta. Amazon Neptune's best features include its multiple servers, each supporting different languages such as OpenCypher, SparkQL, and RDF. For the same RDF graph or property graph, we could use multiple languages to query on different servers. This is exceptional because we have one graph DB with two endpoints exposed where we could interact with different languages on the same graph. Additionally, Amazon has a Sagemaker Jupyter Notebook which interacts with the Amazon Neptune database itself, providing a clean UI for representing nodes since the Jupyter Notebook has predefined graph representation capabilities through queries.

Developers have benefited from flexibility and performance but pricing has needed further attention
I am only familiar with databases and applications. I am from the development team and I am a user of database and cloud but I don't know the infrastructure. As a user, I deal with the Oracle Database. I know the organization has a license with the product. We don't utilize real-time analytics with MongoDB Atlas. I don't use MongoDB Atlas directly, so I don't know how it can be improved. I would place MongoDB Atlas at a medium level. I would rate it at a six or seven. I believe MongoDB Atlas can improve a little. My overall review rating for this product is six out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The initial setup is actually simple."
"Relational databases are never good at identifying patterns in graphs or other similar relationships, whereas Amazon Neptune is."
"Amazon Neptune as a product by AWS is exceptional because it supports multiple graph models such as RDF and property graph, and it also has support for multiple querying languages such as Gremlin, SparkQL, and OpenCypher, making it very comprehensive in supporting every requirement we had at Zetta."
"The stability of Amazon Neptune is very good."
"The cloud-based nature of this solution makes it flexible and scalable, and I like the fact that you can make the deployment bigger as needed, not having to maintain it yourself."
"MongoDB Atlas is our primary database, and we prefer this because of the reliability of MongoDB Atlas."
"As a tester, it was easy to validate data, access data, make active run queries against it, and retrieve data from it."
"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 valuable feature is the schemaless architecture."
"The initial setup of MongoDB Atlas is straightforward...It is a scalable solution."
"It supports many functionalities, is easier to implement, and the only issue is speed."
 

Cons

"We had a strict time constraint, and it took many sleepless nights to find information in the documentation."
"Amazon Neptune could improve by spreading more awareness for others to have an understanding of the solution because the technology is fairly new. The developer community and larger community do not understand it yet."
"Additionally, the need for downtime during scalability is a concern."
"In my scenario, the integration wasn't easy because ................in Java."
"We need improved query performance."
"It would be great if it were easier to integrate MongoDB Atlas with AWS services. Technical support for MongoDB Atlas could be better."
"MongoDB Atlas should improve its user experience by providing better explanations or a wizard for people working with its UI."
"If it could be cheaper, that would make us happy."
"The initial setup is not too difficult but can be somewhat tricky."
"We had some edge cases where scalability was an issue where a node went offline, and we had to deal with that."
"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."
"The UI application for MongoDB crashes a lot, so we would have to use a third-party plugin to make it work."
 

Pricing and Cost Advice

"Microsoft Azure and Amazon AWS are on par for pricing and Google has been raising its prices."
"The price of MongoDB Atlas is highly affordable."
"We pay for a license."
"We're currently using the Atlas for the night and don't require a license. However, it can be a problem if you want to use their enterprise environment. Then you need to purchase the license."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"The tool is free since it's an open-source product."
"For me, MongoDB is expensive, but I think it is not so expensive for customers."
"It is an open-source platform."
"I am using the free version of the solution."
