Ananya Bl - PeerSpot reviewer
Data Analyst at Capgemini
Daily orchestration of complex ai workflows has boosted my research and automation capabilities
Orchestration primarily decides which agent handles which part of a task and manages errors, retries, and complete state while maintaining the workflow effectively. On the orchestration side, branching, looping, and human approvals support non-linear workflows in production environments with real-time access. Through refined and improved prompts, this helps in closing the loop with actual users. One unique feature that stood out is that every step in the workflow can pause or recover from failures. Instead of finishing the entire agent in one go, this approach is interesting because if there is a minor change in a previously completed step regarding the state, I can re-edit and restart from the beginning. This is truly impressive.

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 major impact that I have noticed is how business users are now being impacted and they are using the platform because they understand it easily."
"Glean Platform has positively impacted our organization, especially in terms of productivity for both us and our customers."
"The best features Glean Platform offers include the ability to create my own agents, for example, I created a self-service agent for my stakeholders, so rather than email me, I sent them a link to an agent where the agent asks them questions and drills down to exactly what they need, and then I get a qualified response from them."
"Glean Platform has increased productivity by at least one hundred hours per week for my organization."
"Life became so easy when we started using Glean Platform."
"Productivity has really skyrocketed."
"I have used many solutions, but Glean Platform is the best, and I would truly appreciate it if everyone considers this platform."
"Since I have joined, I have built around ninety agents with Glean Platform, and it has saved our organization around twenty-seven hours a week for each user, and it has also positively impacted our ARR."
"It is better than the legacy databases, and it is very good with the cloud."
"MongoDB Atlas was explicitly designed to support IoT applications. Many databases offer features tailored for IoT use cases."
"There are many valuable features, but scalability stands out. It can scale across zones. You can define multiple nodes. They have also partnered with AWS, offering great service with multiple features, including built-in backup, all under the same roof, without the need for external tools."
"The scalability is very high, the performance is very high, and the cost is lower as compared to the traditional database for cloud."
"It's flexible. We don't need to have a solid upstream availability failover, and everything is seamless in Atlas."
"Being schemaless is what I like best about MongoDB Atlas."
"It is a solid product, very sustainable, and it takes minimal effort to solve a problem while being very easy to deploy."
"The initial setup of MongoDB Atlas is straightforward...It is a scalable solution."
 

Cons

"I tried pulling in an architecture diagram of a workflow, and it pulled in some other image instead."
"Currently, Glean Platform does not integrate with Teams, Microsoft-owned platforms."
"Sometimes Glean Platform gets slowed down."
"My experience with pricing, setup cost, and licensing is that the licenses were expensive, and it was hard to convince the company to adopt based on that."
"In workflow agents, I would prefer that we do not use AI in every step and instead we have a toggle button or something which can configure whether AI should be used in this specific search field or not, or in this specific node or not, because currently it's using AI in all nodes which sometimes messes up the output."
"I chose seven out of ten because if I could upload PDFs and have them analyzed, or have it integrate with my Gmail and help me go through my emails, that would be very useful, but I do not think it does that."
"Also, the latency that the platform offers is a little high right now; what I have noticed is that on a particular query, the user has to wait a long time in order to get responses."
"Glean Platform can implement more models. The NLP creation could be a little faster, and while debugging is amazing, the routing also needs to provide higher quality outputs sometimes rather than extensive searching."
"The UI application for MongoDB crashes a lot, so we would have to use a third-party plugin to make it work."
"Searching and browsing through the collection must be made easier."
"The replica side, like the venue, can be improved."
"They could explore ways to facilitate deploying MongoDB containers within the platform."
"Going forward, we would like to have pure AWS Cloud (native) storage instead regular storage on the AWS integration side."
"One improvement that I would like to see is a feature to export changes made in the environment, such as creating a new user."
"The solution is expensive overall."
"If it could be cheaper, that would make us happy."
 

Pricing and Cost Advice

Information not available
"The purchasing process through the AWS Marketplace was very good."
"It is too expensive. They need to work on this."
"The price of MongoDB Atlas is highly expensive to use and maintain. They are taking advantage of the users with such a high price."
"MongoDB Atlas is not expensive, and since it's a cloud-based solution, you pay by usage."
"The pricing is good. We originally chose it over DynamoDB because of the pricing."
"The pricing is not that expensive, but it can be, especially when we have deployed it across multiple zones."
"Pricing could always be better."
"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."
