Difference Between Virtualization And Client Server Architecture

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.

Answer: Yes, there is. Virtualization also has the benefit of providing high availability, quicker disaster recovery, and less administration. You could have a setup where multiple VMs provide service for an application. If one VM goes down, you still have the others to service any requests. VMs can be copied as images, so if a disaster were to happen the image can be restored at disaster recovery site much quicker. With fewer physical servers, IT staff can focus on other things other than maintaining the server’s

[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.

This allows arranging IT resources in close proximity with one another, instead of keeping them geographically distributed. This allows for power sharing, higher efficiency in shared IT resource usage, and enhanced accessibility for IT personnel. These are the benefits that naturally popularized the Data Center concept. Modern data centers exist as specialized IT infrastructure used to house centralized IT resources, such as servers, databases, networking and telecommunication devices, and software systems.

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.

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:

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.

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

In today’s world you will find that the concept of virtualization seems to be the all new fad that everyone is jumping on the bandwagon to start using. Were in fact the concepts of virtualization started way back in the 1960 with main frame and Unix systems.

A more proficient IT infrastructure is required as the use of more software increases the needs of powerful and faster PCs. One of the trends that can help this issue is Virtualization. This technology is described as the “abstraction” of the physical elements (such as network resources, operating system and storage) into virtual ones (Portnoy, 2012, p.2). Virtualization allows a physical machine to run several virtual machines (VM).

Large corporations might choose to consolidate their IT system in one virtualized (and very expensive) server farm saving on hardware, support and maintenance costs over time.

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.
