Advantages And Disadvantages Of Virtualization

Virtualization is a combination of software and hardware engineering that creates Virtual Machines (VMs) - an abstraction of the computer hardware that allows a single machine to act as if it were many machines, or a computer that does not physically exist as a piece of hardware. The hardware that is seen by the operating system is emulated in an effort to separate the physical hardware from operating system. This allows the virtual machine to be moved and hosted on any machine independent of hardware. Virtualization technology is possibly the single most important issue in IT and has started a top to bottom overhaul of the computing industry which is why many companies around the world have are using its softwares to enhance their business opportunities.

Purpose: The purpose of this presentation is to persuade my audience that using virtualization technology is beneficial for both organizations and the environment. I would like my audience to realize that implementing virtualization can have positive effects for organizations and the environment. My central idea is that virtualization technology cuts down on cost.

a virtual machine from one physical host to another in the event of a failure to provide fault tolerance.

A complete installation of an operating system that runs in a software environment emulating a physical computer.

VNC is also known as Virtual Network Computing, system which uses Remote Frame Buffer protocol (RFB) to allow remote access on another computer under control by network connection.

[P3] Server virtualisation: This is the process of hiding all of the server resources including the amount of servers that a company has and the amount of processors etc. From the people using the server.

In computing, virtualization means to create a virtual version of a resource or device, like a server, storage

By using virtual servers, our company is able to run everything on our physical servers. This includes our ERP, file and print, login server, applications, and mail. Our company will obtain a total of 10 Windows

It allows network administrators to create a virtual server environment by using some of the server’s resources. By doing this, it creates virtual/private servers and one of the benefits of this is that it would cost less money to use virtual servers rather than physical servers as hardware maintenance would not be required. Also, if one virtual server goes down, the others will still be left running. In the example above, there are 4 physical servers. Server Virtualization only needs one physical server to be able to create the virtual servers.

Virtual Computer Laboratory – is a computer environment where a remote user can logon a host, usually a server, and utilize applications and access resource without having to download additional software on the remote

Network Based Virtualization is abstract storage of data applications from the host machine. This is well achieved through fibre channels connection between the machines and the servers running virtualization. The respective operating systems on the separate machines are not a factor to consider as they work independently. For it to achieve its expectations, the following services must be provided as below:

Virtual memory is a typical piece of most working frameworks on desktop PCs. It has turned out to be so basic on the grounds that it gives a major advantage to clients effortlessly.

The first physical server required is installed with the RD Virtualization Host role, which has Hyper-V as a prerequisite, in order to host virtual machines (VMs). Several RD Virtualization Host servers can be pooled to create a larger array of virtual hosts.

As we all know virtualization is the requirement of future. We have evolved from the age of traditional environment to virtual environment.We have grown accustomed to almost all things virtual from virtual memory to virtual networks to virtual storage.The most widely leveraged benefit of virtualization technology is server consolidation, enabling one server to take on the workloads of multiple servers. For example, by consolidating a branch office’s print server, fax server, exchange server, and web server on a single windows server, businesses reduce the costs of hardware, maintenance, and staffing.

Each has their own techniques to convert the existing physical server environment of the organization into virtual servers. Few of them include VMware, Citrix, Oracle, Microsoft and Red Hat. Each of these companies has their own application to implement the virtualization of servers. For example,
