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...

Process migration involves moving the running state of a process from one physical system to another, as is commonly done for virtual machines. In this paper, we describe how Content Centric Networking (CCNx) facilitates process migration through an intuitive naming ontology and version checkpointing. 1Computing Science Laboratory, PARC *corresponding author: [email protected]

Virtual machine (VM) live migration, which is the ability to move a VM from one physical host to another under hypervisor control without suspending for a long time, is a capability being increasingly utilized. With IP mobility, a capability for migrating VMs among distributed sites is provided. We call it the global live migration. However, it affects an application program on a VM compared wi...

The concept of network virtualization, such as network functions virtualization, has attracted considerable attention from telecom carriers and a live migration technique is a key feature of virtualization technology. However, there are some challenges associated with applying server virtualization technology including live migration to a SIP server. Previous work has not dealt with the perform...

A shared distributed infrastructure is formed by federating computation resources from multiple domains. Such shared infrastructures are increasing in popularity and are providing massive amounts of aggregated computation resources to large numbers of users. Meanwhile, virtualization technologies, at machine and network levels, are maturing and enabling mutually isolated virtual computation env...

Abstract Organizations widely use cloud computing to outsource their needs. One crucial issue of is that services must be available clients at all times. However, the may temporarily unavailable due maintenance infrastructure, load balancing services, defense against cyber attacks, power management, proactive fault tolerance, or resource usage. The unavailability impacts negatively on business ...

Virtual machine live migration is a method of moving virtual machine across hosts within a virtualized datacenter. It provides significant benefits for administrator to manage datacenter efficiently. It reduces service interruption by transferring the virtual machine without stopping at source. Transfer of large number of virtual machine memory pages results in long migration time as well as do...
