We performed a comparison between Amazon EMR and Oracle Exadata based on real PeerSpot user reviews.
Find out in this report how the two Cloud Data Warehouse solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."When we grade big jobs from on-prem to the cloud, we do it in EMR with Spark."
"The solution is scalable."
"This is the best tool for hosts and it's really flexible and scalable."
"In Amazon EMR it is easy to rebuild anything, easy to upgrade and has good fault tolerance."
"It allows users to access the data through a web interface."
"The initial setup is straightforward."
"The project management is very streamlined."
"We are using applications, such as Splunk, Livy, Hadoop, and Spark. We are using all of these applications in Amazon EMR and they're helping us a lot."
"The technical support team are real professionals. I admire their technical skills and supports. Their supports are really admirable."
"On-premises Exadata is just as stable as the cloud version. It's a very stable platform."
"Backup/Restore performance: Fast backups, fast restores (especially useful for creating clone environments)."
"The performance on the databases is good."
"Before using this machine, we took no less than two days to run a report. Now, we can do it within five hours. So, there is a lot of improvement."
"What I like best about Oracle Exadata is its good performance. It's also a very fast solution."
"Parallelism is the most valuable feature."
"This product can noticeably enhance performance of contextual Oracle databases."
"There is room for improvement in pricing."
"The dashboard management could be better. Right now, it's lacking a bit."
"Amazon EMR can improve by adding some features, such as megastore services and HiveServer2. Additionally, the user interface could be better, similar to what Apache service provides, cross-platform services."
"The most complicated thing is configuring to the cluster and ensure it's running correctly."
"There were times where they would release new versions and it seemed to end up breaking old versions, which is very strange."
"Modules and strategies should be better handled and notified early in advance."
"As people are shifting from legacy solutions to other technologies, Amazon EMR needs to add more features that give more flexibility in managing user data."
"We don't have much control. If we have multiple users, if they want to scale up, the cost will go and increase and we don't know how we can restrict that price part."
"The solution could always be more stable and more reliable."
"A room for improvement in Oracle Exadata is that it's not very easy to use in a microservices environment. It's not easy to split databases, and if this was easier to do in Oracle Exadata, it would make the solution better. What I'd like to see in the next release of Oracle Exadata is for it to become more modular, so you can use it in a context where the data layer is spread between many independent services."
"It's too expensive per terabyte. It's complex."
"The performance could be improved."
"The management monitoring tools are quite important and an area that needs some improvement."
"It is difficult to evaluate return-on-investment because of the way billing is handled for the product. This should be improved by oracle."
"We used the support from Oracle Exadata to complete the implementation."
"Oracle Exadata could improve the monitoring system in the enterprise manager, it could be more user-friendly. In most Oracle tools there is a lot of functionality, and sometimes you need to do five or six clicks to find metrics, and sometimes it's a waste of time."
