The Virtual Machine Placement (VMP) problem is a challenging optimization task that involves the assignment of virtual machines to physical in cloud computing environment. placement can significantly affect use resources cluster, with subsequent impact on operational costs and In this paper, we present an improved algorithm for VMP, based Parallel Ant Colony Optimization (PACO), which makes eff...

By pervasiveness of cloud computing, a colossal amount of applications from gigantic organizations increasingly tend to rely on cloud services. These demands caused a great number of applications in form of couple of virtual machines (VMs) requests to be executed on data centers’ servers. Some of applications are as big as not possible to be processed upon a single VM. Also, there exists severa...

Cloud computing is formally known as an Internet-centered technique used for purposes in the cloud network. It must compute on a system where application may simultaneously run many connected computers. uses resources to achieve efficiency of data centres using virtualization concept cloud. The load balancers consistently allocate workloads all virtual machines avoid overload situation. process...

Efficient resource allocation is one of the critical performance challenges in an Infrastructure as a Service (IaaS) cloud. Virtual machine (VM) placement and migration decision making methods are integral parts of these resource allocation mechanisms. We present a novel virtual machine placement algorithm which takes performance isolation amongst VMs and their continuous resource usage into ac...

Virtual machine placement to the PMs of the cloud datacenter is one of the important problems in cloud environment to provide better service to the cloud users. This research work proposed techniques to improve the performance of virtual machine placement in cloud environment. The proposed placement algorithm consisted of two main tasks. The first task optimizes the scheduling, while the second...

In order to achieve the virtual machines live migration, the two "pre-copy" and "post-copy" strategies are presented. Each of these strategies, depending on the operating conditions of the machine, may perform better than the other. In this article, a new algorithm is presented that automatically decides how the virtual machine live migration takes place. In this approach, the virtual machine m...
