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

"The initial setup is very simple and straightforward; it's not overly complex or difficult, and with AWS, implementation is not an issue anymore, so from the user's perspective you just create the database and it's as easy as that."

"It's flexible. We don't need to have a solid upstream availability failover, and everything is seamless in Atlas."

"MongoDB Atlas is a database that is quite fast, stable, and reliable."

"It is a solid product, very sustainable, and it takes minimal effort to solve a problem while being very easy to deploy."

"You can start quickly on projects which allow you to store many things."

"The most valuable feature is the schemaless architecture."

"Our databases used to be in-house. Now, they are in the cloud with MongoDB and everything is much easier."

"It's a good solution for NoSQL databases."

More MongoDB Atlas pros

"It is a scalable product."

"The performance of the tool is valuable."

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

"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."

"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."

"Exadata is a highly stable and mature solution."

"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."

"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

"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."

"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."

"The price of the solution should be reduced."

"The installation was straightforward except for the network hardware because it was a little complicated to make the connection with our VPC on AWS."

"I would like to have better performance for user experience with the solution."

"We had some edge cases where scalability was an issue where a node went offline, and we had to deal with that."

"MongoDB Atlas should support containerization."

"The speed when combining two documents is concerning."

More MongoDB Atlas cons

"Oracle's support could be better."

"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."

"We use artificial intelligence for deep learning, and it would be a huge benefit to implement this in Oracle Exadata."

"The solution's pricing could be improved."

"Customer Service: I had no answer when asking why the Customer Support Identifier is invalid Technical Support: The Customer Support Identifier provided was invalid. This means that I had no support, unfortunately."

"The customer's default choice is the on-premise version of this solution. Oracle needs to market the cloud version better."

"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."

"The support must be faster."

More Oracle Exadata Express Cloud Service cons

Pricing and Cost Advice

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

"The pricing is acceptable for enterprise tier."

"The tool is free since it's an open-source product."

"The price of MongoDB Atlas is highly affordable."

"We pay for a license."

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

"We pay for the license on a monthly basis. It's not cheap or expensive. For smaller companies, it's definitely expensive."

"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."

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."
