Domains

Consumers in the subscription service inventory are identified by type. Most consumers will have a type of system, meaning that each individual server subscribes to its own entitlements for its own use. There is another type of consumer, though, which is available for server groups, the domain type. domain-based entitlements are not allocated to a single system; they are distributed across the group of servers to govern the behavior of that group of servers. (That server group is called a domain.)

There are two things to keep in mind about domain entitlements:

• Each member of the domain is still registered to the subscription service as a system consumer and added to the inventory individually.

• The domain entitlements apply to the behavior of the entire server group, not to any one system.

The domain entitlement simply governs the behavior of the domain. A domain entitlement is not limited to a specific type of behavior. Domain entitlements can describe a variety of types of behavior, such as storage quotas or the maximum number of messages to process per day. The entire domain is bound to the subscriptions when one of the domain servers subscribes to the domain entitlements using the CentOS Subscription Manager tools, and the entitlement certificate is replicated between the domain servers.
