Challenges for Establishing Trust in Clouds

Establishing trustworthy Clouds is the ultimate goal of most current research in Cloud computing. The Cloud dynamism increases the complexity of establishing and assessing Cloud trustworthiness. In this chapter we demonstrate the effects of the Cloud dynamic nature on the trust relationships amongst Cloud entities and between users and the Cloud provider. We then identify the major challenges that would need to be tackled to mitigate the consequences of Cloud dynamics. We conclude with a set of research directions for establishing trust in Clouds. Part of these will be explored in subsequent chapters.
