In the virtualization technique, numbers of different components are involved to manage the network, storage, memory. Live migration is the key concept in which the live or active virtual machine is migrated from one host to another host i.e. physical server without disturbing the live environment and the services. This feature is useful for handling the different tasks like power management, I...

A key aspect of cloud computing is the promise of infinite, scalable resources, and that cloud services should scale up and down on demand. This thesis investigates methods for dynamic resource allocation and management of services in cloud datacenters, introducing new approaches as well as improvements to established technologies. Virtualization is a key technology for cloud computing as it al...

science and technology world is using computers in different branches as much as possible. virtual reality has variety of application in different engineering fields. simulating softwares increase the accuracy and process speed of analysis. in this research the aim is to use this concept through milling process on cnc machines, so the students can learn objects effectively and eagerly. the appl...

The field of live VM (virtual machine) migration has been a hotspot problem in green cloud computing. Live VM migration problem is divided into two research aspects: live VM migration mechanism and live VM migration policy. In the meanwhile, with the development of energy-aware computing, we have focused on the VM placement selection of live migration, namely live VM migration policy for energy...

The industry and government have recently acknowledged used virtual machines (VM) to promote their businesses. During the process of VM, some problems might occur. issues, such as a heavy load memory, large CPU, massive disk, high network time-defined migration, interrupt business processes. This paper identifies migration among hosts for VM overcome problem within defined time frame migration....

Live virtual machine (VM) migration is a technique for transferring an active VM from one physical host to another without disrupting the VM. In principle, live VM migration enables dynamic resource requirements to be matched with available physical resources, leading to better performance and reduced energy consumption. However, in practice, the resource consumption and latency of live VM migr...

This paper contributes to the growing knowledge of how to migrate existing systems to cloud computing environment. An increasing number of companies are expected to migrate their systems to cloud enabled infrastructures. Since migration is likely to encounter several kinds of challenges, it is important to identify and share the process and requirements of migration projects in order to build a...

Nowadays, there are lots of problems in Cloud data center such as high energy consumption and low efficiency. We model a cloud environment with physical hosts and virtual machines, and design an Energy-Aware Virtual Machine Scheduling strategy (EAVMS) to reduce energy consumption and improve utilization rate by integrating system resource such as computing, storage and bandwidth resources. Expe...

Implementing and maintaining file systems is painful. OS functionality is notoriously difficult to develop and debug, and file systems are more so than most because of their size and interactions with other OS components. In-kernel file systems must adhere to a large number of internal OS interfaces. Though difficult during initial file system development, these dependencies particularly compli...

We consider the Infrastructure as a Service (IaaS) model for cloud service providers. This model can be abstracted as a form of online bin packing problem where bins represent physical machines and items represent virtual machines with dynamic load. The input to the problem is a sequence of operations each involving an insertion, deletion or updating the size of an item. The goal is to use live...
