Virtualizing the physical resources of a computing system to improve sharing and utilization has been done for decades. Virtualization had once been confined to specialized server and mainframe systems, but improvements in the performance of platforms based on Intel technology now allow those platforms to efficiently support virtualization. However, the IA-32 and Itanium processor architectures...

Virtualization has received much attention the past few years. However, it is anything but new, as one of the first implementations were done in the 1960s to create a multi user system by running multiple instances of a single user operating system. Virtualization mechanisms have evolved much since that time, and an ever increasing number of similar technologies have been collected under the vi...

Virtualization is increasingly being used as a component in designing secure cyber architectures. The proposed applications include strong isolation, monitoring, fault tolerance, execution replay, etc. However, there are various virtualization approaches which differ in their security implications, proper applications, overheads, requirements, and most importantly threat models. Firstly, virtua...

Next Generation Data Centers (NGDC) are transforming labor-intensive, hard-coded systems into shared, virtualized, automated, and fully managed adaptive infrastructures. Virtualization technologies promise great opportunities for reducing energy and hardware costs through server consolidation. Moreover, virtualization can optimize resource sharing among applications hosted in different virtual ...

Server consolidation has become an integral part of IT planning to reduce cost and improve efficiency in today’s enterprise data centers. The advent of virtualization allows consolidation of multiple applications into virtual containers hosted on a single or multiple physical servers. However, this poses new challenges, including choosing the right virtualization technology and consolidation co...

For the last two decades, virtualization processes have been considered developing phenomena in management studies, particularly within the context of the creation of interand intra-organizational networks, establishing strong relationships with customers and the appreciation of intangible assets in companies. The purpose of this paper is to define the concept of virtualization from a marketing...

Despite its current popularity, para-virtualization has an enormous cost. Its diversion from the platform architecture abandons many of the benefits that come with pure virtualization (the faithful emulation of the platform API): stable and well-defined platform interfaces, single binaries for kernel and device drivers (and thus lower testing, maintenance, and support cost), and vendor independ...

Graphics processing units (GPUs) provide orders-ofmagnitude speedup for compute-intensive data-parallel applications. However, enterprise and cloud computing domains, where resource isolation of multiple clients is required, have poor access to GPU technology. This is due to lack of operating system (OS) support for virtualizing GPUs in a reliable manner. To make GPUs more mature system citizen...

An increasing number of grid applications manage data at very large scale, of both size and distribution. In this paper we discuss data access and data processing services for such applications, in the context of a grid. The complexity of data management on a grid arises from the scale, dynamism, autonomy, and distribution of data sources. The main argument of this paper is that these complexit...

The performance of graphics display of virtual machine improves with the strong support from development of virtualization technology and computer hardware. However, in terms of graphical display mechanism there is a difference between the virtual environment and the traditional environment. So how to measure the performance of graphics display in virtualization environment effectively is espec...
