Apparatus, system, and method for service component qualifiers for the declarative specification of quality of service

An apparatus and system are disclosed for implementing service qualifiers that define on-demand management requirements for a loosely coupled software service in a service component architecture (SCA) for an integration server by associating a service qualifier with one or more of an SCA service reference, an SCA wire, an SCA interface, or an SCA implementation based on an SCA component definition, requiring the integration server to augment an implementation execution for the SCA service to honor the service qualifier; and accepting user modification and definition of declarative service qualifiers. By allowing the association of service qualifiers with SCA service references, SCA wires, SCA interfaces, and SCA implementations, additional quality of service with which components are executed can be maintained.
