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."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."
"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 solution is scalable."
"Amazon EMR's most valuable features are processing speed and data storage capacity."
"It has a variety of options and support systems."
"On-premises Exadata is just as stable as the cloud version. It's a very stable platform."
"Regarding features, there are so many that we can offer to customers. When we sell Exadata Cloud, there are many options to choose from, especially when it comes to enterprise database options. In my experience, the main features that are appreciated are various ones like GPS and the assortment of security options."
"It is the best solution for OLTP and data warehousing."
"The tool performs well with a large database."
"It is a highly relevant option with extreme performance."
"Backup/Restore performance: Fast backups, fast restores (especially useful for creating clone environments)."
"Oracle has reliable solutions and this one is no different."
"Complete management occurs from one single address instead of different servers."
"The problem for us is it starts very slow."
"There were times where they would release new versions and it seemed to end up breaking old versions, which is very strange."
"The initial setup was time-consuming."
"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."
"Amazon EMR is continuously improving, but maybe something like CI/CD out-of-the-box or integration with Prometheus Grafana."
"There is room for improvement in pricing."
"The legacy versions of the solution are not supported in the new versions."
"The dashboard management could be better. Right now, it's lacking a bit."
"Oracle Exadata could improve the platform performance tuning should be easier, automated, and user-friendly."
"The scalability can be improved as it is not a parallel execution."
"The solution takes a lot of time to clone the environment. I would like to see some improvement in the cloning support or the time it takes on the storage side."
"There is one aspect to Exadata that I dislike, and that's the inconsistency with other databases. When you try to get Exadata to function with another type of database like SQL, or others, there should be reliable and consistent operation. When this is improved on, we should start to see more applications growing the market."
"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."
"There's room for improvement in terms of deployment, as it could be made faster and more user-friendly."
"The initial setup process is very difficult and extremely complex."
"It's too expensive per terabyte. It's complex."
