Virtualization has been widely adopted in data centers around the world for improving resource usage efficiency; particularly helping to make these computing environments more energy-efficient. Server virtualization allows for on-demand allocation (using either migration or replication) of virtual machines (VMs), which run the web applications and services, to physical servers. In this paper, w...

Cloud computing is a style of technology that is increasingly used every day. It requires the use of an important amount of resources that is dynamically provided as a service. The growth of energy consumption associated to the process of resource allocation implemented in the cloud computing is an important issue that needs to be taken into consideration. Better performance will be acquired by...

In order to meet the demands of operation monitoring of large scale, autoscaling, and heterogeneous virtual resources in the existing cloud computing, a new method of live virtual machine (VM) migration detection algorithm based on the cellular neural networks (CNNs), is presented. Through analyzing the detection process, the parameter relationship of CNN is mapped as an optimization problem, i...

Mobile agent has developed for decade, and widely implemented in distribute computation. However, traditional mobile agents including strongmigration and weak-migration mobile agents still have some weakness. With the fabric of Grid virtual organization architecture, the mobile agent has gain great advantage comparing to those old mobile agents system. In this paper, a novel formalized mobile a...

Virtualization is an innovation that has widely been utilized in modern data centers for cloud computing to realize energyefficient operations of servers. Virtual machine (VM) migration brings multiple benefits such as resource distribution and energy aware consolidation. Server consolidation achieves energy efficiency by enabling multiple instances of operating systems to run simultaneously on...

Today’s complex applications must face the distribution of data and code among different network nodes. Computation in distributed contexts is demanding increasingly powerful languages and execution environments, able to provide programmers with appropriate abstractions and tools. Java is a wide-spread language that allows developers to build complex software, even distributed, but it cannot ha...

Cloud computing and Network Function Virtualization (NFV) use cases proposed by ETSI can improve network caching when an adequate optimization algorithm is used. A cache placement algorithm is proposed based on these virtualization tools. Moreover, a cache placement protocol is presented to support the cache migration. Optimal cache and Virtual Machine (VM) placement and migration, and optimal ...

Resources form the basis of a Grid. Resource management and load balancing are the main areas of concern in a distributed, heterogeneous and dynamic environment like Grid. Load balancing may further cause Job migration or in some cases re-submission of Job. In this paper a number of job migration algorithms have been surveyed and studied which have resulted because of the Load balancing problem...

Infrastructure as a Service (IaaS) in cloud computing provides Infrastructure as a service for the demand of user from small instance to large instance in pay per use model. The services include like computer resource, networking and data storage. An API (Application Programming Interface) is used to access the infrastructure and a dashboard to control the server and to create and manage differ...

To meet the demand for resource oversubscription in cloud computing environments, future Infrastructure-as-a-Service (Iaas) cloud platforms need to provide extremely high consolidation levels of idle or underused virtual machines, while responding quickly to changes or spikes in virtual machine (VM) workloads. In this paper, we present a survey of virtual machine based placement automation solu...
