Since agents have the ability to migrate to outperforming resources they can potentially balance the load of heterogeneous systems. However, to balance resources efficiently agents must take the load into account. Thus, to support the agent migration strategy the application of server selection systems has been proposed recently. Server selection systems keep track of the load of network and ho...

Virtualization technology brings great conveniences to cluster and data center management. By using this technique, we can reconstruct a new computing environment quickly and easily. Compared to the traditional cluster environment, load balancing in a virtualized environment needs to address several new problems. This paper focuses on live migration strategies for load balancing in the virtuali...

Load balancing is one of the main challenges in a Virtual Machine (VM) Environment in order to ensure equal utilization of all the available resources while avoiding overloading a subset of machines. In this paper, we propose an efficient load balancing strategy based on VM live migration. Unlike previous work, our strategy records the history of mappings to inform future placement decisions. W...

Virtualization is an important enabling technology for many large data centers and cloud computing environments, and virtual machine (VM) migration plays a key role in the load balancing among the hosts of the data center. However, the existing load balancing schemes based on VM migration have serious influence on the fault-tolerant level of the services in the data center, and thus the reliabi...

Virtual machines (VMs) dynamic consolidation is effective to improve the utilization of resources and energy efficiency in cloud environment. However, the obligation of providing high quality of service to customers leads to the necessity in dealing with the energy performance trade-off, as aggressive consolidation may lead to performance degradation. Current solutions to the problem of host lo...

In systems aiming at high-speed distributed applications, load balancing plays an essential role. If a process can be easily broken down into several sub-parts, it is possible to do the load balancing transparently to the user application. This is possible if processes consist of multiple threads, distributed objects, or logical nodes. Then some of these parts could be transparently migrated fr...

Live migration enables a running virtual machine to move between two physical hosts with no perceptible interruption in service. This allows customers to avoid costly downtimes associated with hardware maintenance and upgrades, and facilitates automated load-balancing. Consequently, it has become a critical feature of enterprise class virtual infrastructure. In the past, live migration only mov...

Load balancing in grid based distributed computing environment increases the availability and scalability of entire system. Dynamic load balancing has the potential to perform better than static load balancing, but they are inevitably more complex. The overhead involved is much more but one can not negate their benefits. Load balancing strategies try to ensure that every processor in the system...

BACKGROUND Migration is a worldwide phenomenon in recent times. Recently, documented studies suggest that the change in environments involved in migration may have an influence on children's allostatic load related to health and well-being. OBJECTIVE The aim of this review is to systematically search the extant literature and critically examine the evidence on how migration affects allostatic...

This paper discusses the problem of building an operating system with process migration support. Process migration is the act of transferring a process between two machines. It enables dynamic load distribution, fault resilience, and data access locality. In the first section of the paper we formulate the major requirements for process migration mechanism, namely: enabling migration of broad cl...
