Live virtual machine migration allows the movement of a running VM from one physical host to another with negligible disruption in service. This enables many compelling features including zero downtime hardware upgrades, dynamic resource management, and test to production service migration. Historically, live migration worked only between machines that shared a common local subnet and storage s...

Virtualization technology reduces cloud operational cost by increasing cloud resource utilization level. The incorporation of virtualization within cloud data centers can severely degrade cloud performance if not properly managed. Virtual machine (VM) migration is a method that assists cloud service providers to efficiently manage cloud resources while eliminating the need of human supervision....

This paper proposes and evaluates a mechanism for preserving and restoring the execution state of Java applications. A framework is developed, utilising the functionality provided in the Java Platform Debugging Architecture to locate the exact instruction of computation, at the time of program suspension. With the aid of bytecode modification, processing is resumed at the point of suspension, w...

In Infrastructure-as-a-Service (IaaS) clouds, users manage the systems in virtual machines (VMs) called user VMs through remote management systems (RMSes). To allow users to manage their VMs during failures inside the VMs, IaaS usually provides out-of-band remote management. This management is performed indirectly via an RMS server in a privileged VM called the management VM. However, it is dis...

Cloud service centers have the problems such as untrusted virtual machines and frequent migration caused by instantaneous peak. In this paper, trusted machine is measured dynamic exponential smoothing prediction algorithm used to filter requests, ensure that a will migrate at time. The trustworthiness of level agreement (SLA) for cloud services maintained, efficiency utilization center resource...
