Virtualisation is a prevalent technology in current computing. Among the many aspects of virtualisation, it can be employed to reduce hardware costs by server consolidation, implement "green computing" by reducing power consumption and as an underpinning process for cloud computing enabling the creation of a range of virtual networks and virtual supercomputers. This paper presents performance...
Virtualisation is a prevalent technology in current computing. Virtualisation can reduce hardware costs by server consolidation, implement "green computing" by reducing power consumption and is an underpinning process for cloud computing enabling the creation of a range of virtual networks and virtual supercomputers. This paper presents performance measurements for a cloning system known...
System call interposition is a powerful method for regulating and monitoring program behavior. A wide variety of security tools have been developed which use this technique. However, traditional system call interposition techniques are vulnerable to kernel attacks and have some limitations on effectiveness and transparency. In this paper, we propose a novel approach named VSyscall, which leverages...
Cloud computing has become a popular computing paradigm in which virtualized and scalable resources are consolidated to provide services over Internet. However, the resource capability of a single cloud is generally limited, and some applications often require various cloud centers over Internet to deliver services together. Therefore, a Virtual Organization (VO) will be a promising approach to integrate...
With the increasing prevalence of large scale cloud computing environments, how to place requested applications into available computing servers regarding to energy consumption has become an essential research problem, but existing application placement approaches are still not effective for live applications with dynamic characters. In this paper, we proposed a novel approach named EnaCloud, which...
Live migration provides transparent load-balancing and fault-tolerant mechanism for applications. When a Virtual Machine migrates among hosts residing in two networks, the network attachment point of the Virtual Machine is also changed, thus the Virtual Machine will suffer from IP mobility problem after migration. This paper proposes an approach called Hypervisor controlled Mobile IP to support live...
