Virtualization is a technique that partitions a physical computer server into two or more virtual subsystems (or guests), each of which behaves as if it were a separate physical system. Through virtualization, more efficient usage of resources can often be achieved. However, virtualization comes with cost. In particular, the virtualization manager and the individual operating systems installed ...

Few issues in the IT arena are regarded with more interest and passion than virtualization. Virtualization refers to technologies designed to provide a layer of abstraction between computer hardware systems and the software running on them. Here, we are discussing the key concepts of virtualization if you want to implement the virtualization within your environment. Many different vendors have ...

Virtualization is an irreplaceable technique for efficient management of hardware resources in the field of information technology and computer science. With this phenomenal technology come challenges that hinder proper performance analysis of virtualized systems. This study focuses on virtualization implementations, various enterprise solutions, characterization of observations, concerns, pitf...

Virtualization in cloud computing has been the latest evolutionary technology in current applications of various industries and IT firms are adopting Cloud Technology. The concept of cloud computing was introduced long back. Since its inception there have been many number of new innovations implemented by different experts and researchers etc. Virtualization in cloud computing is very effective...

Virtualization technology is widely used in server consolidation, high performance computing, and cloud data center due to its benefits on high resource utilization, flexible manageability, and dynamically scalability. However, it also introduces additional performance overheads. It’s worthy to evaluate the overheads and to find the bottleneck of virtualization in different scenarios. In this p...

Virtualization is used to ease computing resource management, resource utilization and running multiple heterogeneous or homogeneous operating systems on a single physical machine. Virtualization offers many advantages such as reducing fiscal costs, easing system migration, running legacy applications, easing backups and disaster recovery, and utilizing the shared resources over traditional dat...

Virtualization is emerging as an important technology in future systems, providing an extra layer of abstraction between the hardware and operating system. Previous work on virtualization has focused on the partitioning, isolation, and encapsulation features of virtual machines and their use for different applications, but mainly in the context of a specific processor architecture. In this pape...

Over the last few years, the use of virtualization technologies has increased dramatically. This makes the demand for efficient and secure virtualization solutions become more obvious. Container-based virtualization and hypervisor-based virtualization are two main types of virtualization technologies that have emerged to the market. Of these two classes, container-based virtualization is able t...

Virtualization offers many benefits such as live migration, resource consolidation, and checkpointing. However, there are many cases where the overhead of virtualization is too high to justify for its merits. Most desktop and laptop PCs and many large web properties run natively because the benefits of virtualization are too small compared to the overhead. We propose a new middle ground: on-dem...

In my last issue in Volume 5 Issue 1, I articulated the benefits of Clouding computing and in particular, I focused on how Africa might benefit if there is a drive to change the model of computing. In this follow-up piece, I was to go more into the virtualization technology and how Africa especially African Higher Education institutions chocked with the scarcity of resources and severely under ...
