Configure Policies and Roles to Access Resources

You may use the following methods to access cloud resources securely without storing user credentials: Oracle Cloud Infrastructure Resource Principals, AWS Amazon Resource Names (ARN)s, Azure service principal, or Google service accounts.

• Use Resource Principal to Access Oracle Cloud Infrastructure Resources
  You can use an Oracle Cloud Infrastructure resource principal with Autonomous Database. You or your tenancy administrator define the Oracle Cloud Infrastructure policies and a dynamic group that allows you to access Oracle Cloud Infrastructure resources with a resource principal. You do not need to create a credential object and Autonomous Database creates and secures the resource principal credentials you use to access the specified Oracle Cloud Infrastructure resources.
• Use Amazon Resource Names (ARNs) to Access AWS Resources
  You can use Amazon Resource Names (ARNs) to access AWS resources with Autonomous Database.
• Use Azure Service Principal to Access Azure Resources
  You can use an Azure service principal with Autonomous Database to access Azure resources without having to create and store your own credential objects in the database.
• Use Google Service Account to Access Google Cloud Platform Resources
  You can use a Google service account to access Google Cloud Platform (GCP) resources from an Autonomous Database instance.
