Abstract
Virtualization plays a very vital role in the big cloud federation. Live and Real-time virtual machine migration is always a challenging task in virtualized environment, different approaches, techniques and models have already been presented and implemented by many re- searchers. The aim of this work is to investigate various parameters of Real-time and live data migration of virtual machines in stateful and data context at the application level. The migration of one virtual machine to another requires some time depending on the network bandwidth, guest availability, hardware limitation overcomes, resource allocation, server reallocation, hypervisor compatibility and many more. To enhance and ensure the performance and optimization of the time this work presents the some analysis in the form of different time stacks in multiple piece of data stored in the virtual machines. To optimize the migration time virtual machine checkpoints are used in order to achieve the better results by using the xen hypervisor memory technique which dynamically allows the migration of the configured memory while the allocated memory could be discarded for a while. By this the bad memory remains un-migrated only the good memory consisting the used data would be migrated by means of Real-time.
Highlights
As the demand of cloud computing is increasing, storage and communication resources within data centers (DC) are developing new ways for the distributed resources of computing and sharing infrastructure by using virtualization
VM Migration with no Load Live Migration is the practice of transfer of the Virtual Machines active memory state and accurate execution state over a high- speed network, which permits the VM to shift from running on the source host to destination host
WORK This work presents some set of methods and approaches for the analysis off VM live migration in data sharing perspective between the VMs in run-time
Summary
As the demand of cloud computing is increasing, storage and communication resources within data centers (DC) are developing new ways for the distributed resources of computing and sharing infrastructure by using virtualization. In other words, sharing of access or clusters is known as migration of virtual machines, means moving a VM from one source host to another sink host. Migration is useful in maintenance of VMs. if one VM fails, through live migration the VM host failure recovery could be achieved. If one VM fails, through live migration the VM host failure recovery could be achieved Live migration makes these invisible and seamless to users and end users [4]. Virtual machine migration between the single/multiple virtual machines on the basis of data availability, state maintenance in terms of time using multiple scenarios of data context in virtualized environment
