Oracle Autonomous Database in Enterprise Architecture

By: Bal Mukund Sharma, Krishnakumar KM, Rashmi Panda

Overview of this book

Oracle Autonomous Database (ADB) is built on the world’s fastest Oracle Database Platform, Exadata, and is delivered on Oracle Cloud Infrastructure (OCI), customer data center (ExaCC), and Oracle Dedicated Region Cloud. This book is a fast-paced, hands-on introduction to the most important aspects of OCI Autonomous Databases. You'll get to grips with concepts needed for designing disaster recovery using standby database deployment for Autonomous Databases. As you progress, you'll understand how you can take advantage of automatic backup and restore. The concluding chapters will cover topics such as the security aspects of databases to help you learn about managing Autonomous Databases, along with exploring the features of Autonomous Database security such as Data Safe and customer-managed keys for Vaults. By the end of this Oracle book, you’ll be able to build and deploy an Autonomous Database in OCI, migrate databases to ADB, comfortably set up additional high-availability features such as Autonomous Data Guard, and understand end-to-end operations with ADBs.

BOM and SKUs for autonomous databases

There are two components to Autonomous Databases:

  • Infrastructure component: You need to subscribe to Exadata Cloud Infrastructure for an OCI deployment or ExaC@C infrastructure for a C@C deployment.
  • Database OCPUs: Subscribe hourly per active OCPU consumed, using either License Included or the BYOL type. Billing happens monthly at an aggregate level, a total of all active OCPUs, for each Exadata Cloud Infrastructure resource.

There are two scenarios possible in terms of licensing: existing Oracle customers may have already invested in Oracle databases and options. Oracle provides flexibility to use BYOL while provisioning an Autonomous Database in the Oracle cloud. This option brings down the service cost significantly. The other option is the License Included service deployment where customers do not own prior licenses of Oracle databases.


If you are using BYOL, it is feasible to consistently change from 16 or fewer OCPUs to more than 16 OCPUs. The main prerequisite is that your BYOL should incorporate RAC when scaling past 16 OCPUs. For the most accurate policies and the latest information, you should check Oracle’s site.

ADB-D on OCI pricing details can be found on the ADB pricing pages. ADB on ExaC@C pricing details can be found on Oracle’s website under the Pricing information page:

On OCI, the license type is defined at the Exadata infrastructure level. On ExaC@C, this is defined at the Autonomous VM cluster level. As of today, you can only use one license type (License Included or BYOL) on an Exadata rack until multiple VM clusters per rack are supported on ADB-D and ADB-ExaC@C, respectively.
