Cloud computing has revolutionized the information technology industry by enabling elastic on demand provisioning of computing resources. The increase of Cloud computing has resulted in the organization of large-scale data centres around the world contain thousands of total nodes. This paper presents overview of cloud computing, issues in cloud computing, novel techniques, and software for dist...

In this article, virtualization security concerns in the cloud computing domain are reviewed. The focus is toward virtual machine (VM) security where attacks and vulnerabilities such as VM escape, VM hopping, cross-VM side-channel, VM-based rootkits (VMBRs), VM mobility, and VM remote are mentioned and discussed according to their relevance in the clouds. For each attack we outline how they aff...

In Infrastructure-as-a-Service (IaaS) clouds, users manage the systems in virtual machines (VMs) called user VMs through remote management systems (RMSes). To allow users to manage their VMs during failures inside the VMs, IaaS usually provides out-of-band remote management. This management is performed indirectly via an RMS server in a privileged VM called the management VM. However, it is dis...

Selective strengthening of the vastus medialis (VM) muscle is a conservative treatment used to address some patellofemoral joint (PFJ) problems. The objective of this study was to examine the effects of varying VM strength on PFJ kinematics and contact pressures and areas. We tested five fresh-frozen cadaveric knees using a custom knee jig, which permits the simulation of physiologic quadriceps...

In diesem Dokument wird dargestellt wie in einem Migrationsprojekt bei einem Lebensversicherer die Wiederverwendung vorhandener Komponenten durch den Einsatz von Ablaufmodellierung unterstützt wurde. 1 Projektaufgabe Die Migration eines Lebensversicherungsbestandes stellt aufgrund der fachlichen Komplexität der Daten und der Anwendungen ein sehr aufwändiges Geschäft dar, welches sich über Monat...

VM Migration for Autonomic Fault Tolerance provides the continuous availability for applications in the event of virtual machine failures along with the benefits of improved performance and manageability. Multipath correlation coefficient approach for VM migration has been proposed, which takes into account the overutilization of CPU without performance degradation based on work variability. Th...

Since Infrastructure-as-a-Service (IaaS) clouds contain many vulnerable virtual machines (VMs), intrusion detection systems (IDSes) should be run for all the VMs. IDS offloading is promising for this purpose because it allows IaaS providers to run IDSes outside of VMs without any cooperation of the users. However, offloaded IDSes cannot continue to monitor their target VM when the VM is migrate...

We have isolated stable teniposide (VM26)-resistant cell lines from human cancer KB cells by stepwise exposure to increasing doses of the drug. At each step, we have purified VM26-resistant cell lines. KB/VM-a, KB/VM-b, KB/VM-1, KB/VM-2, KB/VM-3, and KB/VM-4 showed 3-, 6-, 12-, 16-, 74-, and 95-fold higher resistance to VM26 than did KB. We have further characterized KB/VM-2 and KB/VM-4 which s...

Introduction Virtualization is widely used in consolidation projects and as a basis for new server deployments. The benefits in energy efficiency, space, cooling as well as cost are immediately apparent, as many applications don't require the full computational power of even the smallest available new server today. However, in addition to all these benefits, virtualization also introduces some ...
