QOS based Approach for Web Service Recommendation Systems

Udhav Lahane, K.N.Shedage

Abstract: A web service is a software system designed to support interoperable worldwide computer-to-computer interaction. Web services have been widely deployed for developing service-oriented applications in both industry and academia in recent years. The number of publicly available Web services is immovably increasing on the Internet. However, this generation makes it hard for a user to select a proper Web service among a large amount of service candidates. An unsuitable service selection may cause many problems (e. g. , unsuitable performance) to the resulting applications. This paper, propose a novel CF-based Web service recommendation system for helping users select services with optimal Quality-of-Service (QoS) performance. QoS (Quality-of-Service) is an important concept in cloud computing. It is very complicated to take decision on choosing the cloud services depending on QoS requirements. These requirements have to be fulfilled by both cloud service providers and cloud users. So, Excellent Service Selection is needed to obtain high quality cloud applications. With the increasing number of Cloud services, Quality-of-Service (QoS) is usually employed for explaining non-functional properties of Cloud services. The QoS performance of cloud applications becomes low because of unreliable Internet connections. In this paper, we have presented a worldwide survey on QoS Ranking in Cloud Computing with respect to their Limitations and Inferences
