Resources
Resource | Description |
---|---|
Domain | Defines the management scope for tenants, services, and resource pools. A domain consists of one or more z/OS systems. A domain can include z/OS systems from more than one sysplex. A z/OS system can be in a single domain or in multiple domains that are managed by a single instance of z/OSMF. A cloud domain is defined by a z/OS system programmer who acts as the landlord. Each cloud domain is assigned one or more middleware system programmers who act as domain administrators. A base z/OSMF configuration includes one domain by default — the default domain. |
Resource pool | Identifies the z/OS resources that are required by a z/OS software service. In a cloud domain with multiple tenants, the resource pool defines the scope of resource sharing and resource isolation. For example, a resource pool can define a range of dedicated IP addresses or ports for each tenant. |
Tenant | Defines the group of users who have the authority to provision software instances. A tenant consists of a user or group of users that have contracted for the use of specified services and pooled z/OS resources that are associated with the services in a domain. A base z/OSMF configuration includes one tenant by default — the default tenant. |

Objects
Object | Description |
---|---|
Instance, or software services instance | Represents software that is provisioned by using templates. |
