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."Amazon EMR is a good solution that can be used to manage big data."
"It has a variety of options and support systems."
"In Amazon EMR it is easy to rebuild anything, easy to upgrade and has good fault tolerance."
"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 solution is pretty simple to set up."
"The solution helps us manage huge volumes of data."
"One of the valuable features about this solution is that it's managed services, so it's pretty stable, and scalable as much as you wish. It has all the necessary distributions. With some additional work, it's also possible to change to a Spark version with the latest version of EMR. It also has Hudi, so we are leveraging Apache Hudi on EMR for change data capture, so then it comes out-of-the-box in EMR."
"The ability to resize the cluster is what really makes it stand out over other Hadoop and big data solutions."
"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."
"The data replication is very good."
"The most valuable feature of Oracle Exadata is its capabilities for storing and processing data. It is very good for our domain."
"We like the tool’s features like Smart Scan, Hybrid Columnar Compression, and the TFA."
"The most valuable feature is that you have the same familiar environment of an Oracle database but with the additional performance you get from this architecture."
"Compression is a great feature, where one can really save a lot of storage."
"It has improved the performance, now we run with more performance cores with less CPU to attend all the database demands. Reducing Time to Market, increase our ability to face the competition with speed and low cost."
"The ease of setup is an eight out of ten."
"Modules and strategies should be better handled and notified early in advance."
"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 product must add some of the latest technologies to provide more flexibility to the users."
"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 dashboard management could be better. Right now, it's lacking a bit."
"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."
"There is room for improvement in pricing."
"The initial setup was time-consuming."
"The solution could always be more stable and more reliable."
"There is a feature for security, but it is not included in the first purchase of this solution. That means if you need to increase the security, you need to buy the security feature which doesn't come by default on these solutions."
"Exadata would be improved with single dashboard visibility."
"License or upgrade management can be difficult and time consuming because it requires login to a separate console."
"It's too expensive per terabyte. It's complex."
"The customization can sometimes be difficult to achieve."
"It is difficult to evaluate return-on-investment because of the way billing is handled for the product. This should be improved by oracle."
"Oracle Exadata compatibility with the analytics could be better and the OBIEE could improve. Oracle BI to Exadata needs to be improved. Even if the full analytics practice for Oracle should be improved and when compared with other solutions it is weak."
