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.

Have achieved excellent performance and seamless integration with effective cost control in cloud solutions

When customers are migrating from Oracle Exadata Express Cloud Service and need to remove some of their test and development environment, what happens in normal virtualization is that they can just switch it off, but in ExaCS, they need to terminate the entire thing. Most of the customers are not aware of this, so they keep spending money even if they want to shut down their UAT environment or development environment, so Oracle needs to make it simpler in terms of reducing the bill on ExaCS when customers want to shut down certain environments. Today, you have to terminate the entire VM, and only then your billing will stop. The only functionality I would expect from Oracle Exadata Express Cloud Service is that if Oracle is able to support Oracle MySQL Enterprise also on Exadata, that will solve a lot of problems.

Quotes from Members

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

Pros

"It is better than the legacy databases, and it is very good with the cloud."

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

"In my previous company, the product allowed us to build a database in a highly regulated environment with the ability to get distributed storage, and we used MongoDB as a distributed storage to set up this environment for a critical business application with millions of dollars."

"The auto-scaling feature is the most valuable aspect."

"The solution is easy to use, the console is user-friendly, and overall a well-designed solution. It takes a complex system and makes it easy to understand. Additionally, the solution is always advancing and they provide a roadmap into what is coming in the future."

"As a tester, it was easy to validate data, access data, make active run queries against it, and retrieve data from it."

"The product is simple to use and enterprise-ready. It is also open-source."

"The initial setup is straightforward."

More MongoDB Atlas pros

"Having the prediction happen in the modular format allows you to start with a lower version of Exadata and then you can keep on upgrading it as per your requirement."

"I would rate Oracle Exadata Express Cloud Service ten out of ten for its overall solution."

"Exadata is a highly stable and mature solution."

"One of the most valuable parts of the solution is the high availability within the system and the performance enhancement without making any changes or fine-tuning the databases."

"I highly recommend Oracle Exadata Express Cloud Service as a very good solution if you can afford it."

"In the cloud, Exadata is more scalable. The on-prem version was limited. It wasn't that scalable because it only came in a quarter rack, half rack, and full rack. In the cloud, it scales to what you need."

"With this cloud service, a development team can get a database immediately, without long negotiation with other services."

"What is most valuable about this solution is there is no comparative solution by any other vendors."

More Oracle Exadata Express Cloud Service pros

Cons

"The administration is not very interactive. It's not very friendly for developers."

"Customer support needs improvement knowledge-wise."

"The UI is not currently designed in a manner to make it possible for a non-technical person or a layman to update the database easily."

"MongoDB Atlas is effective for unstructured and semi-structured data, but when it comes to OLTP transactions, its performance declines."

"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."

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

"The cost needs improvement. The product is good, but the cost that we paid for it is expensive, so it wasn't that valuable."

"When I edit a document from a document, a lot of clicking is involved, like changing data type manually from a drop-down. It would be super nice if I could just edit the document in a JSON format. The JSON-based document editor should have a multi-language feature. Also, it would be great if there was a connect option from Google Looker Studio."

More MongoDB Atlas cons

"The solution's pricing could be improved."

"Oracle's support could be better."

"The support must be faster."

"The customer's default choice is the on-premise version of this solution. Only when Oracle or the partners like us, can explain to customers the cloud value proposition, and if the compliance authorities allow, they can look into this cloud solution. It will take some time for Oracle to change its perception of customers' de-facto standards. Exadata used to be treated as a black box, which is not the case now. The customer is aware of what is happening inside, how the configurations have been made, and what patching has been applied. Oracle needs to market the cloud version better."

"The product's installation process needs improvement. It could be more accessible."

"Scaling Oracle Exadata Express Cloud Service can be done, but the process is a little tedious, which could be an area for improvement in the solution."

"I feel there is a need for better integration with Google Maps and Google Earth. This is crucial for me in the geographical facilities of the environment."

"The only downside is the difficulty in monitoring, and that's why I would like to implement MySQL database."

More Oracle Exadata Express Cloud Service cons

Pricing and Cost Advice

"I am using the free version of the solution."

"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."

"It is an open-source platform."

"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."

"We pay for a license."

"The solution is fairly priced. I rate the pricing a seven out of ten."

"For me, MongoDB is expensive, but I think it is not so expensive for customers."

"MongoDB Atlas is not expensive, and since it's a cloud-based solution, you pay by usage."

More MongoDB Atlas pricing and cost advice

"The price of this solution is very comparative to others on the market. There is no direct comparison between this solution and with something else because I do not see any other similar product."

"I think Oracle pricing is usually above average market price."

"The tool is not cheap, but it is not really expensive."
