"Amazon Redshift is very fast. It has really good response times. It's very user-friendly."
"The initial setup is easy."
"I like the cost-benefit ratio, meaning that it is as easy to use as it is powerful and well-performing."
"The most valuable features of Amazon Redshift are that its fast and efficient. We have lots of TBs of data and it's very fast."
"I find the most valuable features to be the MPP style of processing, which mostly all of the data warehouses provide. The ability to integrate all other AWS services, such as NSS and S3, with little effort is very helpful. The service is well maintained, there are update patches frequently."
"Oracle is known to be the number one in their industry; the help and support, the features they are giving the clients comparing to other databases, the new technology, the provide a good solution."
"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."
"A very stable solution, which we have hardly any problems with."
"The performance on the databases is good."
"The most valuable feature is the time to solution."
"Exadata is a fantastic machine. Two features stand out. The first is the resource input/output management tool that allows you to manage the resources to the neck on the Exadata box."
"The business intelligence is very good."
"Oracle Exadata's performance is one of its best features. We very satisfied with it."
"Amazon should provide more cloud-native tools that can integrate with Redshift like Microsoft's development tools for Azure."
"There is some missing functionality and sometimes it's so difficult to work in. We need to convert these functionalities using VACUUM inside Amazon Redshift and then it causes some complexity."
"This solution lacks integration with non-AWS sources."
"I would like to improve the pricing and the simplicity of using this solution."
"Improvement could be made in the area of streaming data."
"Redshift's GUI could be more user-friendly. It's easier to perform queries and all that stuff in Azure Synapse Analytics."
"The solution has four maintenance windows so, when it comes to stability, I think it would be better to decrease their number."
"There are too many limitations with respect to concurrency."
"The integration with third-party applications regarding access management security could be better."
"I have found Oracle Exadata to be scalable. However, you have to purchase more hardware, such as memory."
"In a future release, I would like to see some upgrade analysis advisors to help with a clear roadmap on steps that need to be taken and some of the automated processes."
"Tech support sometimes takes some time to identify and rectify issues."
"We need a monitoring tool which can in one place, where we can manage, monitor the entire Exadata components."
