Resources

The following are the key resources in the Cloud Provisioning tasks.

Table 1. Resources for Cloud Provisioning
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.

The following are the key roles in the Cloud Provisioning tasks.

Table 2. User roles for Cloud Provisioning
Role	Performer	Description
Landlord	z/OS system programmer	Defines the cloud domains and the associated system resources for the cloud. The landlord also designates one or more users as domain administrators.
Domain administrator	Middleware system programmer	Manages a domain. The domain administrator is responsible for defining services, tenants, and resource pools for the domain, and managing the relationship across tenants, services, and resource pools.
Resource pool networking administrator	Network administrator	Manages the resource pool for the networking resources in the cloud, such as network configuration policies.
Resource pool WLM administrator	Performance administrator	Manages the resource pool for the WLM resources in the cloud, such as WLM policies.
Security administrator	Security administrator	Maintains the installation's security manager, such as RACF.
Template approver	System programmer or security administrator	Responsible for approving the pending approval records that are associated with the template.
Consumer	Application programmer	Has access to the software services and resource pools for a tenant. This user can provision a software services instance by using a software services template, and can manage the lifecycle of a software services instance.

The following are some basic objects that you work with in the Cloud Provisioning tasks.

Table 3. Objects for Cloud Provisioning
Object	Description
Instance, or software services instance	Represents software that is provisioned by using templates.
Template, or software services template	Represents a z/OS middleware or a z/OS middleware resource service. A template consists of workflows and input variables that can be used to provision z/OS software, actions that can be used with the provisioned software (the instance), and documentation.
