Replacement of services is a typical solution of adaptation. The first step of replacement is to find a candidate substitution for the service using service discovery.[CD-JRA-2.3.4]

Service quality and negotiable parameters can be an aspect used during discovery of services. Therefore, quality monitoring data should be available for discovery engines.[CD-JRA-2.3.4]

Service Discovery is the process of finding services that match the requirements of the service requestor. Runtime service discovery is an important ingredient for self-adaptation. [CD-IA-1.1.1] {ETC: self-adaptation}
The capability of automatically identifying services able to fulfill certain requirements. From a more technical viewpoint Service Discovery is the action of retrieving a Service description, abstract or concrete, whose capabilities match the constraints of the input abstract service. In case an abstract service is returned it is usually an abstract workflow e.g. a functionally equivalent workflow composed by more elementary services than the one provided as input. Discovery is usually performed by means of profile matching. [BreinGlossary]

SOA4ALL: An activity of finding and identifying a service that might fulfill user requirements. [SOA4ALL]
