Ensures that users experience a good return on investment

Firstly, a user should prepare the operating system for installation, and then we have to copy the software to install the product. When dealing with scenarios related to Oracle Real Application Clusters, users need to add nodes and storage. The setup process is a little bit complex compared to DB2. The setup process of Oracle Database In-Memory takes around five to six hours to install Oracle Real Application Clusters, if everything is okay, apart from which the other processes will take a day. The solution is deployed on an on-premises model. The cloud-based solution is available for testing and development, and it need not be installed in your environment. A user just needs to do a few clicks and select the database, after which it automatically gets installed in the cloud. Only in the on-premises version of the product, there is a need to do some work in the tool.
