Virtual Network Computing

The hospital’s administrative network consists of Apple iMACS and thin computers that use 1000Base T with CAT 6 cables. All work stations belonging to Executive Management has Apple iMAC computers with 24” monitors, 2.4 GHz speed, 2 GB RAM, and a 500 MB hard drive. Human Resources, OPNS, and the Finance Senior Managers have Apple iMACS with 20” monitors, 2 GHz speed, and a 350 MB hard drive. All of the systems have OS virtualization and use the MAC Operating System X, Leopard, and Windows XP. OS virtualization allows separate, isolated virtual environments to be used on a single server. The MAC Operating System X is a UNIX system that is both simple and powerful. Leopard further enhanced the system by making it faster and more reliable. Windows XP is a product of Microsoft but it is able to be installed on any MAC using a native version of Microsoft Office. This way users are able to create documents using MS Word, make presentations using PowerPoint, and

at a time,they are commonly connected to a LAN and run multiuser operating system.The resources which has to be managed

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.

VNC is stands for a Virtual Network Computing which is an open source platform for accessing desktop on remote machines with the help of LAN over a WAN or Internet connection. In this project discuss various methods of developing or building a virtual network with provides a good security to each one of them. VNC is platform independent so we can use any operating system such as UNIX, Windows, MAC OS x etc. It will also cover the open connection and tunneled connection of SSH (Secure Shell). In my project, I will apply technique to build a secure virtual network. In this present era there are many multinational company in the market company users are able to share their resources and applications without any kind of high level on software and hardware resources. Mobility is important in this fast peace world therefore the

The networking of the system is recommended after a system study and the fact that there has been a 100% expansion of the demand for the system- from 5 to 50 have been noted. It is also shown that as of now there are machines that are stand alone with windows 7 operating system. The task is to provide a network connectivity that would provide direct connections between the employees, and be centralized in the operation. This essentially requires the creation of a network. This means that all the computers must be installed with a network card and this would be the case with windows 7. The question then comes is if there must be windows networking or use other protocols. We can also partly use the most modern practical solutions.

Cloud computing is the practice of using remote storage for applications and data. The idea itself is not a new one; it has been in use for many years albeit under different names. In the earliest days of the computer age machines had to be physically large to contain the hardware required to do their jobs. It was impractical and prohibitively expensive to provide one of these mainframes for individual users; not to mention for what they were used for, unnecessary. Instead, one central computer was wired to several terminals that users could interface with. Typically, only large organizations such as, major corporations or government agencies could afford one of these machines or had need of one. This was the birth of cloud computing. Until the early 1980s this system was typical for any organization requiring large amounts of processing power. It was considered unnecessary and difficult to put the nuts and bolts of applications onto users’ desktop machines. Rather, by keeping applications in a central location, they could be managed and updated more easily and large amounts of storage space and processing power were not needed on desktop machines. Indeed, before this time there were no desktop machines mass produced that could achieve this level of power. This was about to change.

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

Virtualization’s rate of adoption is completely characterized by the five characteristics described in the framework for the concepts of innovation (Luftman & Bullen, 2004, p. 189). It is perceived to be better than physical servers in its ability to host multiple operating systems and share the host’s resource. Its encapsulation of resources allows it to operate as if it was a physical machine yet it is totally virtual giving it a relative advantage. It is compatible with all baseline operating systems on the market. Complexity in implementation is minimal making it more attractive to adopt. The vendors allows for free downloads and trials. Its visibility in competition with Microsoft’s Hyper-V has shown multiple advantages. (Luftman & Bullen, 2004, p. 190)

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.

It also supports controlling functionality by using graphical screen update from controlled device [9]. VNC architecture is basically based on RFB protocol for transferring all the information. It required two type of application for proper working server application and client application Client side is called viewer and it is responsible for viewing shared desktop. Server side interprets all events which are received from client and inject them into self-system.

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.

VMware provides the vSphere application and similarly Microsoft provides Hyper-V application for the purpose of virtualization. Most of the major datacenter in the world use the VMware as their solution for virtualization. VMware dominates the server virtualization market in world due to its innovations, strategic partnerships and rock-solid products [2]. We shall be using VMware products to virtualize the hypothetical organization. The reasons for choosing VMware [3] are:

is an open source which is available with source code. Virtual network computing is a Graphical sharing desktop that shares system and allows to remotely control the desktop interface of one computer to another. The Raspberry Pi uses Linux based operating systems .The ARM11 is according to the version 6 of the ARM on the linux no longer run (in current releases), including the Ubunto.

This is one of the crucial advantages of networking computers. Everyibe can find and share data because of networking. This is beneficial for large organizations to maintain their information in an
