SRC: A service registry on cloud providing behavior-aware and QoS-aware service discovery

Aiming to discover the most suitable service cater to the discovery request of service consumer which includes functional requirements and nonfunctional requirements, this paper proposes a service registry model named as SRC (Service Registry on Cloud) which is an extension of the keywords based service registry model and deployed as a cloud application to provide behavior-aware and QoS-aware service discovery services. SRC stores the semantic descriptors of Web Services and the feedbacks of dynamic status of QoS of Web Services as GFS files in a cloud, and uses MapReduce mechanism to process these files. The running results of an instance of SRC deployed in an experimental environment have shown that SRC is effective and feasible.
