SLA-based risk analysis in cloud computing environments

Abstract

The cloud computing has been evolved in recent years which led many customers to utilize the cloud computing technologies. The research work in this area has spread due to many issues that have coincided with the vast growth of the cloud computing technologies. On the other hand, the cloud security concern has become one of the important issues that cloud computing introduces. One of the main components of cloud services is the service level agreement (SLA) that works as a contractual document between the cloud providers and their customers and states some metrics and parameters that must be enforced by the cloud providers or consumers. Despite various issues of the SLA in cloud computing, there is one issue that has not been discussed frequently in cloud computing security, which is the SLA in term of risk management. This research tends to perform SLA-based risk analysis in cloud computing environments. Moreover, it evaluates different SLA parameters such the risk factor, the response time factor, and the service cost factor. This paper also designates the importance of considering risk management as an SLA parameter in the negotiation stage between the provider and the consumer. However, it looks for the relation between those SLA metrics and risk factor associated with the cloud services
