active (primary state)

The condition of a service after it has been invoked and executed by a service consumer program is referred to as the service's active state. An active service is considered to be actively carrying out functions as per the service capability that was invoked.

The term "active" represents one of two primary states a service can exist as, the other being passive. Primary states are of relevance to the implementation of the Service Statelessness design principle that emphasizes the optimization of state data deferral and delegation.

Note that an active service may be either stateful or stateless, depending on what form of state management-related processing (if any) it is required to carry out.
