Virtual machine (VM) placement in the cloud infrastructure is an important problem that remains to be effectively addressed. Fine-grained virtual machine resource allocation and reallocation are possible in order to meet the performance targets of applications running on virtual machines. On the other hand, these capabilities create demands on system management, especially for cloud data center...

Cloud computing is becoming more and more popular in computing infrastructure and it also introduces new security problems. For example, a physical server shared by many virtual machines can be taken over by an attacker if the virtual machine monitor is compromised through one of the virtual machines. Thus, collocating with vulnerable virtual machines, or “bad neighbours”, on the same physical ...

With the emergence of cloud computing, computing resources (i.e., networks, servers, storage, applications, and services) are provisioned as metered on-demand services over networks, and can be rapidly allocated and released with minimal management effort. In the cloud computing paradigm, the virtual machine is one of the most commonly used resource carriers in which business services are encap...

Cloud computing enables users to have access to resources on demand. This leads to an increased number of physical machines and data centers in order to fulfill the needs of users which are continuously on the increase. The increase in the number of active physical machines is directly proportional to the increase in the energy consumption. Thus, minimization of energy consumption has become on...

The utilization of cloud data centres in combination with Virtualization technology has advantages of running more than one virtual machine in a single server. The data centres are a collection of many servers, allocation of VM to Host is known as VM placement. VM placement problem was examined in this paper with focus for maximum utilization of the resources and energy reduction. Switching off...

In traditional data center numbers of services are run onto the dedicated physical servers. Most of the time, these data centers are not used their full capacity in term of resources. Virtualization allows the movement of VM from one host to the another host ,which is called virtual machine migration, so these data centers can consolidate their services onto lesser number of physical servers th...
