This feature automatically encrypts data before it is written to storage and automatically decrypts data when the data is read from storage. Some application vendors do a deeper integration and provide TDE configuration steps using their own toolkits. With the WALLET_ROOT parameter, the wallet will be stored in subdirectory name tde. TDE is part of Oracle Advanced Security, which also includes Data Redaction. Note that TDE is certified for use with common packaged applications.

For any Oracle instance running in a VM managed (Azure, OCI, or AWS) by you, the above steps are still valid. You can perform other keystore operations, such as exporting TDE master encryption keys, rotating the keystore password, merging keystores, or backing up keystores, from a single instance only. This will set some TDE-related DB parameters and create a TDE wallet/keystore and generate a master key as well and convert the wallet to an autologin wallet. The performance overhead of using AES256 is roughly considered 40% slower than AES128, therefore, I would recommend AES128 which is a balanced solution.
