In recent years, cloud computing technology has become one of the most significant IT infrastructures. Cloud users are increasing every day; thus, cloud must be able to handle the huge number of requests received at any given moment, causing concerns for resourced load balancing. The load balancing problem occurs when some cloud resources are overloaded with user tasks while other resources are...

Two network-virtualization architectures, namely, network segmentation and network paging, were investigated. They are analogical to two memory-virtualization architectures: segmentation and paging. Network paging, which is relatively new and is based on a type of network-address translation (NAT), is focused on. This architecture requires smaller packet size and has several more advantages ove...

Live migration of virtual machines is an important approach for dynamic resource scheduling in cloud environment. The hybrid-copy algorithm is an excellent algorithm that combines the pre-copy algorithm with the post-copy algorithm to remedy the defects of the pre-copy algorithm and the post-copy algorithm. Currently, the hybrid-copy algorithm only copies all memory pages once in advance. In a ...

Live migration of virtual machine (VM) is one of the most important virtualization technologies to facilitate the management and improve the performance of data centers. In this paper, we propose a fast convergent live migration approach called FMC. It is a self-adaptive method which synchronizes the state of the VM migrated between the source and target host by log tracing and replaying instea...

Green cloud data center has become a research hotspot of virtualized cloud computing architecture. Since live virtual machine (VM) migration technology is widely used and studied in cloud computing, we have focused on the VM placement selection of live migration for power saving. We present a novel heuristic approach which is called PS-ABC. Its algorithm includes two parts. One is that it combi...

Virtualization has gained traction in a wide variety of contexts. The rise of Cloud Computing and the wide adoption of the OpenFlow API in computer networks are just a few examples of how virtualization has changed the foundations of computing. In general, the term ”virtualization” refers to the process of turning a hardware-bound entity into a software-based component. The end result of such p...

Now a days cloud computing is one of the fast growing technology in the field of computer science and information technology because of online, cheap and pay as use scheme. The cloud computing is mainly a business-oriented model to provide on demand computing resource. It has become popular in short time because of its attractive services like easy to use, pay as use and accessibility of its se...

Cloud computing is a technology that used for distributed computing, on a network. It is meant network-based services that these services are provided by virtual ISPs. Virtual machine migration has been tout as one of the crucial technologies that improving data center efficiency, such as maintaining load balance and reducing energy cost. However, traditional approaches of could not avoid the s...

The cloud computing is the architecture in which cloudlets are executed by the virtual machines. The most applicable virtual machines are selected on the basis of execution time and failure rate. Due to virtual machine overloading execution time and energy consumption is increased at steady rate. In this paper, Gravitational technique is applied in which weight of each virtual machine is calcul...
