Virtualization technology plays a great role in cloud computing. Virtualization supports creation and migration of virtual machines (VM) on physical hosts. Live migration provides the load balancing of virtual machine. One of the objectives of live migration is that it should have minimum migration time as well as downtime so that application running on VM will be suspended for negligible time....

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 ...

Live migration of virtual machines has been a powerful tool to facilitate system maintenance, load balancing, fault tolerance, and power-saving, especially in clusters or data centers. Although pre-copy is extensively used to migrate memory data of virtual machines, it cannot provide quick migration with low network overhead but leads to large performance degradation of virtual machine services...

Virtual machine (VM) placement is very important for cloud platforms. While techniques, such as live virtual machine migration, are very useful to balance the load in the data centers, they are expensive operations. In this position paper, we propose to minimize the chance of the load hot spots in the data center by applying the workload patterns of the VMs in the virtual machine placement algo...

Despite significant advances in enabling live virtual machine (VM) migration within a virtualized—cloud— infrastructure, cross-cloud live migration remains an ad hoc, complex process. To create a network environment in which live migration can occur, clouds are beginning to expose virtual networks as a service. Connecting, managing and maintaining membership and routing information for—possibly...

In cloud computing, load balancing, energy utilization are the critical problems solved by virtual machine (VM) migration. Live migration is live movement of VMs from an overloaded/underloaded physical to a suitable one. During this process, transferring large disk image files take more time, hence and down time. proposed adaptive deduplication, based on file size, undergoes both fixed, variabl...

Cloud computing is a result of the continuing progress made in the areas of hardware, technologies related to the Internet, distributed computing and automated management. The Increasing demand has led to an increase in services resulting in the establishment of large-scale computing and data centers, in addition to high operating costs and huge amounts of electrical power consumption. Insuffic...
