Virtualization is one of the biggest buzzwords of the technology industry right at this moment. The fast growth in storage capacity and processing power in enterprise installations coupled with the need for high availability, requires Storage Area Network (SAN) architecture to provide seamless addition of storage and performance elements without downtime. The usual goal of virtualization is to ...

Virtualization was invented more than thirty years ago to allow large expensive mainframes to be easily shared among different application environments. As hardware prices went down, the need for virtualization faded away. More recently, virtualization at all levels (system, storage, and network) became important again as a way to improve system security, reliability and availability, reduce co...

Programmability and virtualization have both become the trends of next generation networks. ForCES (Forwarding and Control Element Seperation) is a new programmable framework for network element. We introduce virtualization into ForCES, propose a method of ForCES virtualization, design its framework, implement a prototype system named vForTER, and test its performance in different scenarios. Te...

The concept of virtualization in information technology dates back to the development of programming language compilers that were designed to virtualize the object code. Later virtualization emerged as cutting-edge technology not only for cost reduction of IT operations and support but also for ultimate simplicity, flexibility and agility of the underlying infrastructures. Server virtualization...

Server virtualization is one of the fastest adopted technologies in datacenter history, becoming the overwhelming default build for servers in just a little more than a decade. Customers aggressively moved virtualization from test and development (test and dev) workloads to production workloads. Today, most of the remaining workloads to be virtualized are mission-critical tier 1 workloads. Thes...

This paper proposes a high level maturity in SaaS applications based on virtualization technologies, in which the hardware virtualization focuses on providing the flexible on-demand hosting environment, the application virtualization used to meet the scalable application deployment requirements and data virtualization solves data integration and unified data access problems to ensure multi-tena...

For the majority of common workloads, performance in a virtualized environment is close to that in a native environment. Virtualization does create some overheads, however. These come from the virtualization of the CPU, the MMU (Memory Management Unit), and the I/O devices. In some of their recent x86 processors AMD and Intel have begun to provide hardware extensions to help bridge this perform...

Virtualization has been extended from wired to wireless networks. It improves efficiency and utilization and enables customized service and multi-tenancy. New architectures involving virtualization have been proposed in the major wireless domains such as WiFi, cellular network and wireless application in Internet of things (IoT). Additionally, the use of Software Defined Radio (SDR) gives more ...

Abstract — Ganeti is an open source virtualization management software used in small as well as growing businesses that can help users to manage networks, storage and virtual machines (VMs). Software is built on top of popular virtualization technologies such as KVM, Xen and other open source solutions. This paper contains introduction to Virtualization, introduction to Ganeti that is a cluster...

Virtualization is an ongoing process that transforming daily activities and interactions. Such transformations will be reflected in irreversible changes the organization functioning of societies (socio-historical changes).Virtualization built by reconstructing information communication functions set us apart as human beings are specific to our societies. This text deals with performance these b...
