The database systems can be brought up as standalone or in a RAC cluster that is entirely configured and managed by the database service. In addition to RAC, Exadata systems are also available.

Because the systems are fully managed, they are Maximum Availability Architecture (MAA)-compliant.

Dynamic central processing unit (CPU) and storage scaling features are available, as well as the ability to upsize Exadata deployments across shapes. CPU core usage can be changed hourly to right-size the database system.

For security, there are several features and capabilities. These...
