Can I use both TDE and EBS encyption with RDS Oracle and RDS Oracle custom ?

Yes, both Transparent Data Encryption (TDE) and Amazon Elastic Block Store (EBS) encryption can be utilized with Amazon RDS for Oracle and RDS Custom for Oracle. However, implementing both requires careful consideration of best practices and potential performance implications.

Impact on Latency

• TDE encryption may introduce performance overhead, especially for large tablespaces.
• EBS encryption has minimal impact on performance since AWS handles encryption at the storage level.
• Combining both may slightly increase latency, but the impact depends on workload size and query complexity.
