Towards understanding uncertainty in cloud computing with risks of confidentiality, integrity, and availability

Abstract

An extensive research has led to a general understanding of uncertainty issues in different fields ranging from computational biology to decision making in economics. However, a study of uncertainty on large scale computing systems and cloud computing systems is limited. Most of works examine uncertainty phenomena in users' perceptions of the qualities, intentions and actions of cloud providers. In this paper, we discuss the role of uncertainty in the resource and service provisioning, privacy, etc. especially, in the presence of the risks of confidentiality, integrity, and availability. We review sources of uncertainty, and fundamental approaches for scheduling under uncertainty. We also discuss potentials of these approaches, and address methods for mitigating the risks of confidentiality, integrity, and availability associated with the loss of information, denial of access for a long time, and information leakage
