Server Virtualization Essay

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.

Virtualization is a software technology that makes it possible to run multiple operating systems and applications on the same server at the same time. It’s transforming the IT landscape and fundamentally changing the way that people utilize technology. Virtualization is the single most effective way to reduce IT expenses while boosting efficiency and performance, not just for large enterprises, but for small and midsize businesses too. (Mctigue, 2013)

According to a research done by Nemertes Research, nearly 93% of the organizations it surveyed in 2009 have deployed virtualization in their servers [Ritter09]. However, with the vast benefits that come with adoption of virtualization, new challenges and vulnerabilities also arise at the same time.

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)

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:

Commercial data centers like Equinix and Amazon have to be judicious expanding capacity considering lengthy construction and heavy capital investment. A data center contains aisles and aisles of server cabinets thousands with each costing more than a quarter million containing 64 specialized laptop sized servers essentially a computer. Networking cabinets go together with server cabinets in order to electronically connect any server to another through high-speed fiber cables. The networking cabinets of today consume 25% of the useful floor space for IT cabinets but consist of 40% of the total cost. The data center is clamoring for IT gear that supports a new technology known as Network virtualization to address the conservation of space and

Virtualization is being able to give a physical device the power, through the use of software, to do more than that physical device was technically designed and able to do (Santana, 2014, p. 12). For example, a server can only run one operating system at a time. However, when a hypervisor is used in a server, the hypervisor is a layer of software that acts like the server itself so that many operating systems can be run from that one server. The hardware, in this case a server, has been virtualized. The goal is to use all of the computer’s resources all of the time, and the only way to do that is to have enough things running that the resources are being used consistently and efficiently. An analogy for this could be online classes. If each teacher only had one student, the teacher’s resources of time and expertise would not be utilized efficiently because that one student will not need help all day, every day. If the teacher is assigned to fifteen students, the students can still get help when needed from the teacher, and they would not even be aware that they are not alone in the class. Because it is an online class, the teacher does not need any more physical resources to teach an entire class than was needed for one student. The students are receiving the benefits of being taught by that teacher without needing to be with him or her physically.

Please creatively apply virtualization principles to a physical writing desktop as shown below. Describe the ideas/steps of your strategy. Make any reasonable assumptions (if necessary) to build your strategy on. Hint: think about what are the primary principles of virtualization, what are the types of virtualization, what are the mechanisms/approaches of performing/achieving virtualization. Instruction: Please type your solution to a word file and submit to me by email by the last hour of

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.

Virtualization significantly originates from various structures this was recognized basically by the layer in which the registering framework to which virtualization is connected. All virtualization structures will have an element called a hyper visor or virtual machine screen (VMM). This is the real focal unit which controls every one of

After receiving several students’ complaints regarding poor desktops’ performance over the last year, the organization has decided to analyze the current system to provide suitable solutions. One of the solutions for the B&IT School is implementing a Virtualization technology.

Switch to virtual machines instead of physical servers. This internal business strategy aligns with the overall mission to reduce costs by 5% to fund new projects, such as providing warehousing services to customers. In addition, updating this technology will reduce manpower needed to upkeep servers and free them to work on other projects.

Most of the manufacturing in the organization is automated with the help of high end servers. These physical servers when are overloaded or when they are being used for longer period of time, tend to degrade and malfunction as their components start to fail and this would require replacing them with new ones. This will incur additional cost to the company if the server is not covered under manufacturer warranty or it has expired and is no longer in support by the manufacturer. Thus the organization is in need of virtualization of the physical servers to overcome these problems. The organization has been around for more than three decades and hence is using older applications that won’t run on newer hardware and the current hardware is about to degrade. So in order to save the company from such incidents that could result in major setback in manufacturing, virtualization of these servers is necessary. Another benefit of virtualizing the servers is that the resources such as CPUs, disk size, RAM size of the virtual servers can be increased if the load is too high on the server. This can be done on the fly, without creating an impact to the organization.
