Virtualization in Cloud Computing: NoHype vs HyperWall new approach

In the world of Cloud Computing, virtualization and virtual environments are fundamental basics for data sharing. It provides the guest user with the elements needed to execute his request, while it gives the provider the ability to be housing different guests without risking the security and integrity of data. Virtualization is based on a central component, called a hypervisor, having extra-privileges, which makes it the key component capable of managing the sharing of data and resources. In this paper, we will be analyzing different approaches which try to solve the security issues of hypervisors, and we will try to add our own contribution to increase help solving the problem of security of hypervisors based architectures. © 2016 IEEE.
