  Service matching concerns finding suitable services according to the service
requester's requirements, which is a complex task due to the increasing number
and diversity of cloud services available. Service matching is discussed in web
services composition and user oriented service marketplaces contexts. The
suggested approaches have different problem definitions and have to be examined
closer in order to identify comparable results and to find out which approaches
have built on the former ones. One of the most important use cases is service
requesters with limited technical knowledge who need to compare services based
on their QoS requirements in cloud service marketplaces. Our survey examines
the service matching approaches in order to find out the relation between their
context and their objectives. Moreover, it evaluates their applicability for
the cloud service marketplaces context.
