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...

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.

The exponential growth into more than a dozen buildings across Dallas, Denver, Atlanta and Houston within 10 years meant Granite Properties had hastily bolted together its server system, adding new, and replacing damaged, equipment as needed. To meet the demands of its 130 widespread employees, Granite was employing 30 aging physical servers, each running from its own box.

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...
Virtualization is a technology that creates an abstract version of a complete operating environment including a processor, memory, storage, network links, and a display entirely in software. Because the resulting runtime environment is completely software based, the software produces what’s called a virtual computer or a virtual machine (M.O., 2012). To simplify, virtualization is the process of running multiple virtual machines on a single physical machine. The virtual machines share the resources of one physical computer, and each virtual machine is its own environment.
To begin with, virtualization reduces hardware costs by reducing consolidating equipment. Initially, Seabreeze will reduce the physical server infrastructure by 70%. The project will upgrade the data center to 21 energy efficient servers with enough resources (CPUs, networking, memory, and disk storage) to host the virtual infrastructure. As for storage, the VMs will be stored on a storage area network (SAN). That is to say, the server cluster will be connected to a petabyte SAN for data
Nevertheless, the ability to leverage further productive qualities across a diverse range of hardware – including different processors and relatively low-end solutions as well – provides a compelling argument for the use of Linux across new and emerging server requirements, along with the most appropriate paid-for support model to ensure that there are no issues with such an implementation.

Computer virtualization technology has progressed leaps and bounds in a relatively short period of time. Since its inception in late 1960s, it has developed into a massive technology industry that allows companies and individuals of all status to take advantage of the many possibilities it affords. Virtualization has be a key part of reducing the resources required to deliver our apps and services, while maintaining resiliency and not increased the requirement for 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.
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.
Today’s servers are designed to last for longer periods; however, the idea of keeping up with new data center demands, requires constant hardware upgrade. The main reasons for undertaking server upgrade include; need to extend the server’s life, need to get the most out of the existing servers, the need to make use of the old data center hardware and implications of virtualization. Server virtualization is a critically networking function because it makes one server act as many servers; each with unique applications and Operatin...
Application virtualization is a concept completely based on networks and resource sharing, which is what this subject is all about. Application virtualization technology deals with how an application can be virtualized at the client end from the server side using the network resources.

Data center, in the context of big data, is not only for data storage but it plays significant role to acquire, manage and organize the big data. Big data has uncompromising requirement for storage and processing capacity. Hence the data center development should be the focus for effective and rapid processing capacity. With the increasing scale of data centers, the operational cost should be reduced for the development of data centers. Today’s data centers are application-centric, powering the many business applications, standalone websites and e-commerce offerings on the web. Tomorrow’s data centers need to be data centric: storage and infrastructure capacity must be expanded to support IoT/Big Data-generated information. This also affects future bandwidth in data centers as resources will be mostly consumed by IoT sensors and machines, as opposed to user activity and behaviour.
Virtual memory is an old concept. Before computers utilized cache, they used virtual memory. Initially, virtual memory was introduced not only to extend primary memory, but also to make such an extension as easy as possible for programmers to use. Memory management is a complex interrelationship between processor hardware and operating system software. For virtual memory to work, a system needs to employ some sort of paging or segmentation scheme, or a combination of the two. Nearly all implementations of virtual memory divide a virtual address space into pages, which are blocks of contiguous virtual memory addresses. On the other hand, some systems use segmentation instead of paging. Segmentation divides virtual address spaces into variable-length segments. Segmentation and paging can be used together by dividing each segment into pages.
