Oracle Cloud Terminology

The following table lists the terminology that documentation uses when describing the Oracle Cloud features and functionality. It is important that you have a good understanding of these terms.

Term Definition
Account A unique customer account that can have many Oracle Cloud services. The account corresponds to an individual, an organization, or a company that is an Oracle customer. Each account has one or more identity domains.

An account must have at least one account administrator who is responsible for activating Oracle Cloud services, creating identity domains, monitoring status and usage, and designating other users as account administrators.

To register for a trial or purchase a subscription to an Oracle Cloud service, you must have an Oracle.com account. If you do not have an Oracle.com account, the system prompts you to create an account the first time you attempt to sign up for an Oracle Cloud service.

Data center A facility used to house computer systems and associated components.

Oracle provides data centers in various geographical regions. An identity domain and the services associated with that domain must belong to a specific data center.

Identity domain Controls the authentication and authorization of the users who can sign in to an Oracle Cloud service and what features they can access.

An Oracle Cloud service must belong to an identity domain. Multiple services can be associated with a single identity domain to share user definitions and authentication. Users in an identity domain can be granted different levels of access to each service associated with the domain.

Oracle Public Cloud Services Account/Identity Domain In the case of Oracle Public Cloud Services, an account is a unique customer account that can have multiple Oracle Public Cloud Services of different service types.

Account creation results in creation of an identity domain (IDM slice) for that customer that is leveraged across all Oracle Public Cloud Services services (and across all data centers). During the Oracle Public Cloud Services account setup process, the customer needs to create an account and specify an account name. Using the specified account name, that the identity domain will be implicitly created.

Service A software offering in Oracle Cloud. Oracle offers social, application, and platform services.
Service association An association between service instances that are part of the same identity domain. For example, a new Oracle Java Cloud Service trial automatically includes a new Oracle Database Cloud Service and always creates a new identity domain.
Service instance An instance of one of the service types. For example, an instance of an Oracle Java Cloud Service. A service instance can be a slice of a multi-tenant service infrastructure or a dedicated single tenant service infrastructure.
Service name A name assigned to your Oracle Cloud service. The name must be unique within the identity domain. You can add a longer description to a service to help you identify it, after it is activated. For more information, see Editing Service Descriptions.
Service notification An event reported on the Notifications page that does not require administrative action. This type of notification provides information about upcoming system-wide and service-specific events, such as outages and blackouts.
Trial subscription An Oracle Cloud service that is available for free for 30 days, for trial and evaluation purposes only.
Utilization Metrics that show how much system resources are being consumed by a service. You can use either the My Account or the My Services application to view the utilization metrics for a service.
