Trustworthy Service Selection for Potential Users in Cloud Computing Environment

Abstract

AbstractIn recent years cloud computing has been gaining enormous momentum. Cloud service providers around the world have publicized a large number of cloud services. Increasing numbers of users are drawn to the convenience and economic affordability of cloud services. As cloud services rapidly proliferate, users are faced with the dilemma of service selection, especially since many services offer similar functionalities with equal quality of service (QoS). In a dynamic cloud environment, the uncertain QoS of cloud services, the fuzzy and personalized QoE (quality of experience) of cloud consumers, are now becoming the central challenges to trustworthy service selection for a potential user. Therefore, evaluating the trustworthiness of cloud services and helping potential user select the trustworthy cloud services among abundant candidates, have been the urgent need at the current development stage of cloud computing. This chapter provides an overview of the related work on trustworthy cloud service selection and a case study on the user feature-aware trustworthy service selection for potential users. At the end of this chapter, a discussion is given based on the identified issues and future research prospects.KeywordsCloud computingPotential usersService selectionTrustworthiness
