CS代写|云计算代写Cloud Computing代考|VIRTUALIZATION

Virtualization refers to technologies that are designed to provide a layer of abstraction between layers of hardware and software that decouples the physical hardware from the operating system. Virtualization helps with simplified interaction between these two layers, delivering greater IT resource utilization, and flexibility.

A virtual machine monitor example is shown in Figure $3.2$ where the customer management environment runs on top of Operating System 1 (OS1) and the testing environment runs on top of Operating System 2 (OS2). Both the operating systems run on top of the virtual machine monitor (VMM). The virtualizations of all the resources (e.g., processors, memory, secondary storage, and networks) are being carried by VMM and it also allocates them to the various virtual machines that run on top of the VMM.

Terms Used in Virtualization
A lot of terminology is used in the virtualization technique, but here are a few frequently used terms and their definitions:

Host machine: A host machine is a physical machine which is running the virtualization software. It contains the physical resources such as CPU, memory, hard disk space, and other network resources that the virtual machines utilize.

Virtual machine: A physical machine that is run and maintained by the virtualization software is called the virtual machine. Each virtual machine is implemented as a single or a small collection of files in a single folder on the host system. These virtual machine acts as if it is running on an individual, physical, non-virtualized PC.

Virtualization software: This is a generic term denoting software that allows a user to run a virtual machine on a host machine.

VMM: This is a software solution that implements virtualization to run in concurrence with the host operating system. The virtual machine monitor virtualizes certain hardware resources such as the memory, CPU, and physical disk and creates emulated devices for a virtual machine running on the host machine. All the functionality such as resources allocation, virtualization, and presented to the virtual machine running on the host computer is carried by virtual machine monitor.

Virtualization is using computer resources to imitate other computer resources or an entire computer system. It separates resources and services from the underlying physical environment. Virtualization has three major characteristics that make it absolute for cloud computing:
i. Partitioning: In virtualization, many operating systems and applications are supported on a single physical system by partitioning (separating) the available resources.
ii. Encapsulation: A virtual machine can be represented (and even stored) as a single file, so it can be easily identified based on the service it provides. An encapsulated process could be a business service and can be presented to an application as a complete entity. Therefore, encapsulation protects each application so that it doesn’t interfere with another application.
iii. Isolation: The virtual machine is isolated from its host physical system and other virtualized machines. Because of this isolation, if one virtualinstance crashes it won’t affect the other virtual machines. Also due to isolation the data is not shared among different virtual containers.

VMM：这是一种实现虚拟化以与主机操作系统同时运行的软件解决方案。虚拟机监视器虚拟化某些硬件资源，例如内存、CPU 和物理磁盘，并为在主机上运行的虚拟机创建模拟设备。资源分配、虚拟化以及呈现给运行在主机上的虚拟机的所有功能都由虚拟机监视器来承载。

i. 分区：在虚拟化中，通过对可用资源进行分区（分离），在单个物理系统上支持许多操作系统和应用程序。
ii. 封装：可以将虚拟机表示（甚至存储）为单个文件，因此可以根据其提供的服务轻松识别它。封装的流程可以是业务服务，并且可以作为完整的实体呈现给应用程序。因此，封装保护每个应用程序，使其不会干扰另一个应用程序。
iii. 隔离：虚拟机与其主机物理系统和其他虚拟机隔离。由于这种隔离，如果一个虚拟实例崩溃，它不会影响其他虚拟机。同样由于隔离，数据不会在不同的虚拟容器之间共享。
