Oracle Cloud Account management is the responsibility of you, the customer, and you can assign administrators to manage the account and your subscribed services, just as you do on Oracle Public Cloud.
For example, the initial, designated Oracle Cloud Account Administrator on your team is responsible for receiving the Welcome email and initially logging in to your Oracle Cloud Account on Oracle Cloud at Customer. The initial account administrator can then create additional administrator accounts.
Typically, two or more Oracle Cloud Account administrators on your team to manage your Oracle Cloud Account. They monitor your Cloud Account usage and create and manage Cloud Service instances. They also can create additional Cloud users, who can be assigned specific tasks or roles within the account.
