“…There are mainly 2 types of hypervisors: (1) Type-1 hypervisor is directly implemented on the hardware, so it reaches better performance. (2) Type-2 hypervisor will be hosted by a guest operating system so, it delivers a low level of performance compared to Type (1) hypervisor [3]. Type-1 hypervisor is an example of kernel class, it is also called bare-metal hypervisor because it works directly on the hardware on which its operating system is mounted.…”

Virtualization is now the most efficient and successful procedure to use server resources. Virtualization is a technology that will efficiently allow the instructions or programs based on the available hardware. With the help of virtualization, we can achieve benefits like reduced capital and operating costs, minimized downtime, increased productivity, and good disaster recovery, etc. This work compares the virtual mail server performance on 3 different Hypervisor software. The 3 different type-2 hypervisor software we chose to compare were Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware. A computer system that sends and also receives an email over a network either on LAN or the internet is called a Mail Server. Although large ISPs and public email services have their dedicated hardware, in most cases, the web servers and mail servers are hosted on a single machine by virtualization. When a Mail server is implemented on the hypervisor, it is then considered as a virtual mail server. A virtual mail server is good at load balancing and has many more benefits. This paper presents how to implement a virtual mail server and shows the comparative results of the virtual mail server on different type-2 hypervisor software. HIGHLIGHTS Virtualization will efficiently run the instructions or programs based on the available hardware The virtual mail server has more significant advantages than the standard mail server. It helps in achieving faster deployment of mail servers with fewer hardware requirements Comparison of the performance of the virtual mail server on three different Type-2 Hypervisor software: Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware The web servers and mail servers can be hosted on a single machine by virtualization A virtual mail server is best for load balancing and disaster recovery as well

“…Researchers Arslan and Özbilgin (2017) defined virtualization at the Institute of Electrical and Electronics Engineers' 2017 International Conference on Computer Science and Engineering as "the creation of components, such as hardware platform, operating system, storage, processing power, memory, or network resource, in virtual environments," and highlighted that, "The applications of virtualization are spreading rapidly, and the critical systems are working on virtualization infrastructures." The move towards virtualized systems offers several key engineering and testing advantages that are aligned with the Chief of Naval Operations vision for the future Navy such as reduced space requirements, decoupling software from hardware, greater flexibility and adaptability, and increased speed and frequency of software updates.…”

The US Navy envisions a Fleet that applies advances from the technology sector to improve the delivery of warfighting capability. Due to constraints imposed by legacy hardware design inherent and the inherent limitations of x86 servers, significant inefficiencies exist in the hardware and software delivery process. The US Navy leveraged advancements in virtualization technology to field combat system software in virtual machines, effectively removing computing hardware as a capability limiter. Adoption of hardware-agnostic virtual machines also significantly reduced the delivery timeline for improved warfighting capabilities at a lower cost. This paper will review the evolutionary enhancements in AEGIS Combat System computing architecture and describe why it is critical for the Surface Navy to adopt a new capability delivery model. This paper also outlines the key engineering and testing advantages of the US Navy AEGIS Virtual Twin effort, which recently demonstrated continuous capability delivery to the Fleet. Finally, this paper will explore the multifactor framework of the Balanced Scorecard as a tool to align the benefits of virtualization and advances in computing technology with a new model for future US Navy Combat Systems.

“…Through the MEC processing at the network edge, the data transmission consumes less energy and produces lower latency [18]- [20]. So far, researchers have employed some key technologies of MEC, including Software Defined Network (SDN) [21], Virtualization [22], and Cloud technology [23], in typical applications, such as Intelligent video acceleration, Computing intensive applications, Internet of vehicles and Internet of things (IoT) [24]- [27]. Besides the limited computating ability, some mobile device also suffer from insufficient energy, such as Unmanned Aerial Vehicle (UAV) and IoT [28], [29].…”

That alleviating the heavy computing task, improving spectral efficiency and prolonging battery lifetime have been the key design challenges in Internet of Things (IoT) and intelligent connected vehicles (ICV). This paper studies the optimization of communication, computation and energy resource to minimize the energy consumption in the mobile terminal, where some superior technologies are included, such as Full-Duplex (FD), Simultaneous Wireless Information and Power Transfer (SWIPT), Mobile-Edge Computing (MEC) and Multi-input Multi-output (MIMO). In this model, the MEC-assisted Base station (BS) works in FD mode, then it can transmit and receive signals in the same frequency and time. Moreover, the mobile devices offload some computation tasks to the BS and complete local computations at the same time. Besides, the mobile device harvests the energy from the BS to support its energy consumption. And, our target is to minimize the energy consumption of mobile devices. Since the problem is non-convex, we propose an iterative solving algorithm including a multi-step optimization. First, we obtain the closed-form solution of the CPU frequency. And then, we transform the remain problem into a convex one to solve it by the interior point algorithm. Finally, we obtain the approximate solution by multiple iterations. Simulation results show that the proposed algorithm is superior to the compared schemes. INDEX TERMS Mobile-edge computing, simultaneous wireless information and power transfer, multi-input multi-output, full-duplex, multi-step iteration, vehicular communications.
