You are a Windows 7 administrator at Contoso, a very large and international pharmaceutical company. You have 25 servers in your network running a combination of Windows Server 2000, Server 2003, SuSe Linux. As your Chief Information Officer is brainstorming with you and his/her staff, you mention that you have heard about Virtualization and it may be a very cost effective and efficient way to upgrade everything to Windows Server 2008. Your boss tells you to research the concepts and to get back to him in two weeks with a recommendation.
My solution is to use server virtualization, which would allow multiple servers to be installed on one or more existing servers. This saves floor space and money since you don’t have to purchase new servers or expand the square footage of your server room.
How Virtualization Works
Virtualization is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. You probably know a little about virtualization if you have ever divided your hard drive into different partitions. A partition is the logical division of a hard disk drive to create, in effect, two separate hard drives. Operating system virtualization is the use of software to allow a piece of hardware to run multiple operating system images at the same time. The technology got its start on mainframes decades ago, allowing administrators to avoid wasting expensive processing power. (Search server virtualization, 2013)
The other forms of Virtualization
Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of whic...

...ware templates, cross platform and hybrid resources. With the advantage of reducing the amount of servers and the efficiency of hardware virtualization a company can experience significant cost savings; this also reduces needed floor space which saves the cost of adding on more room for your servers.

Some of technology they will need to decide on will be whether to install a server computer, which is a computer on a network that performs important network functions for client computers, such as serving up Web pages, storing data, and storing the network operating system (and hence controlling the network). Server software such as Microsoft Windows Server, Linux, and Novell Open Enterprise Server are the most widely used network operating systems. As well the network operating system (NOS) routes, manages communications on the network, and coordinates network resources. It can reside on every computer in the network, or it can reside primarily on a dedicated server computer for all the applications on the network. In considering how their workers will communicate with each other in...
Workers are also not being used to their full potential as the majority of the IT budget is going towards them to maintain the current system that they have in place. Carr determines that these problems can be fixed with relative ease by combining three different technologies, Web services, virtualization, and grid computing. The combination will allow for less technology to be wasted and processing power to be used to its full capacity. He tells the reader, this is what the individual will have to do to advance the information technology environment to its fullest potential and continues by listing examples of some of the possible corporations and sources from where this individual could come from, including big computing hardware contributors, information technology hosting operations, an internet extraordinaire and new start up innovators. He concludes the article by pointing out that as dubious as this may be, many other innovations similar to this started the same way and people should not fear to take action on this opportunity, as it will better humanity. I believe that the article provides some good points as it shows us that the
Virtualizing your server lets you run different Operating Systems, such as Windows and Linux, in different virtual servers on the same physical server. Once you have one virtual server configured, you can use that same configuration to set up new virtual servers, which takes just a few minutes. Compared to the hours it takes to configure a new physical server, server virtualization is far more efficient (Marshall, 2011).
A second barrier to entry is switching costs. When IBM and Apple were the only computer systems to choose from people had to make a choice. When you went to buy one system then you had to buy all the software that went along with that system. Ultimately, IBM became the mor...
Due to the fact that companies outsource their production, the technology also benefits money saving by, for example, eluding travel expenses. Moreover it could also avoid the use of an office, because workers could telecommute from home. This can also decrease the time in which a task can be completed by vid...
Hardware, software, support and maintenance costs grow each year with multiple systems in each local region running different types of software and hardware. The application and hardware support teams are larger than could be possible with one integrated solution.
He has excessive expectations of Sullivan. If computers have always been a weakness, then what is the company’s attitude toward technology? The CEO errs in diagnosing the problem as solely IT related, instead of looking to the company’s business leaders too. An IT system alone is not significant unless it becomes more broadly applicable - an integral part of an overall work system of selling the product or service using business competencies. The problem at Lenox is beyond the scope of IT and overlaps into other departments. Only then can a new IT system “deliver” and achieve maximum impact for the
Nokia Networks is a broadband radio network provider, attracting customers all over the globe. Nokia Networks focuses on developing 5G, which is due to replace the old 4G. Networks’ main concern is the accommodation of an increasing amount of data traffic. Networks works towards an improved speed of uploads by developing a radio cloud network. The demand for speed grows as many phones are becoming richer
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.
The reason for this rapid adoption is Linux’s unique ability to provide powerful functionality, security, compatibility, customization at a more cost-effective price than proprietary vendors. In its inception, there were many perceived concerns to utilizing Linux in a corporate infrastructure.

The time required for product development is significantly reduced as well. One need not wait for the end to test the whole functionality. The same has been tested in bits and pieces all the way.
Assigning the precise amount of network capacity in the right place at the right time is no simple task. Network Planners cannot afford to overbuild, as this would consume scarce investment resources that could be better used elsewhere. They also cannot delay expansion as this may result in poor service to customers and under-utilize other network assets. A balanced approach is needed in order to meet the rapidly growing and changing traffic demands. Advanced network planning and design software provides benefit to network planners in the following ways:
