Security-Aware Dispatching of Virtual Machines in Cloud Environment

The cloud computing as a ubiquitous paradigm could provide different services for internet users and Information Technology (IT) companies through datacenters located around the world. However, cloud provider faces several problems such as security and privacy issues in cloud datacenters. Hence, cloud provider has to handlesecurity challenges to gain more profit. In this paper, a Security- Aware Dispatching and Migration model for the virtual machines isproposed in order to prevent Service Level Agreement (SLA) violation. The approach considers the lowest violation in requiredsecurity preservation as the most significant factor for execution of VMs. The results show that lower SLA violation is achieved in our method compared to other common methods. It is also shown that the SLA Violation has an exponential relationship with the VMcomputational capacity which is defined by Million Instructions Per Second (MIPS).
