Cloud computing provides the opportunity to migrate virtual machines to “follow-the-green” data centres. That is, to migrate virtual machines between green data centres on the basis of clean energy availability, to mitigate the environmental impact of carbon footprint emissions and energy consumption. The virtual machine migration problem can be modelled to maximize the utility of computing res...

Preface This work is a continuation of the NomadBIOS project, where Asger Jensen and I designed and built what would now be termed a para-virtualized hypervisor for hosting multiple virtual machines on top of the L4 microkernel, and—to our knowledge—were the first to show the feasibility of live migration of virtual machines across a local network. Focusing on grid computing, our idea was to pa...

Cloud Computing is a paradigm allowing access to physical and application resources online via the Internet. These are virtualized using virtualization software make them available users as service. Virtual machines (VMs) migration technique provided by technology impacts performance of cloud. It significant concern in this environment. When allocating resources, distribution VMs unbalanced, th...

Live Migration is one of the essential operations that require more attention to addressing its high variability problems with virtual machines. We review the existing techniques of resource management to find that there are less modeling to solve this problem. The present paper introduces a novel framework that mainly targets to achieve a computational effective resource management technique. ...

Side and covert channels (referred to collectively as illicit channels) are an insidious affliction of high security systems brought about by the unwanted and unregulated sharing of state amongst processes. Illicit channels can be effectively broken through isolation, which limits the degree by which processes can interact. The drawback of using isolation as a general mitigation against illicit...

The live migration of Virtual Machines (VMs) is a key technology in server virtualization solutions used to deploy Infrastructure-as-a-Service (IaaS) clouds. This process, on one hand, increases the elasticity, fault tolerance, and maintainability in the virtual environment. On the other hand, it increases the security challenges in cloud environments, especially when the migration is performed...

The ability to migrate a virtual machine (VM) from one physical host to another is important in a number of cases such as power management, on-line maintenance, and load-balancing. The amount of memory used in VMs have been steadily increasing up to several gigabytes. Consequently, the time to migrate machines, the total migration time, has been increasing. The aim of this thesis is to reduce t...

With the advent of cloud computing in the arena of IT field energy consumption and service level agreement (SLA) violation emerge as a major problem, which reduces the profit of cloud service providers (CSP) and affect the cloud customers by fencing the reusability and scalability of the cloud data center services. This problem needs to be eradicate for the efficient resource provisioning in cl...

Virtual machine migration is an important tool that can be used in cloud computing environment for load balancing, disaster recovery, server consolidation, hardware maintenance, etc. Currently a few techniques have been proposed to secure the virtual machine migration process. However, these techniques have number of limitations e.g. lack of standard access control, mutual authentication, confi...

The utilization of cloud data centres in combination with Virtualization technology has advantages of running more than one virtual machine in a single server. The data centres are a collection of many servers, allocation of VM to Host is known as VM placement. VM placement problem was examined in this paper with focus for maximum utilization of the resources and energy reduction. Switching off...
