Virtualization Analysis

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.

Storage of data plays a major role in improving the performance of a company and this can happen either offline or online and in various formats.

Developing backup procedures, implementing company-wide, recovery plans need to be developed and offsite backup locations should also be considered

A client/server architecture is an end-to-end systems that contains server hosts (contains the resources and services needed by the client) and clients (users or workstations in the network). “Most client/server networks have more than one client to a server so that the system shares computing power. There are a few different kinds of servers to include file sharing, printer services, email services, database services, web services, and a server can used for it power. Clients can access all of these different servers at one time and the servers can serve many clients.” (Techopedia, 2014) For large businesses with office throughout the country web based computing or cloud computing shows the greatest benefit. In web-based computing it is not the local computer doing all the work but rather computers off site that do the work. The user’s computer runs off of a cloud computing system’s interface software which uses the offsite network computers to do the work.

Information will only have value if customers can access it at the right times. Availability can be affected by system errors, and malicious attacks as well as infrastructure problems. Availability is ensured by maintaining hardware as well as repairing hardware immediately when need arise. A correct functioning operating system should also be maintained in the environment free of software conflicts. Adequate communication bandwidth should also be addressed as well as preventing bottlenecks from occurrence.

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.

A typical Data Center consists of a sturdy, well-built building housing storage devices, servers, internet connectivity and extensive cabling and networking equipment. It also consists of cooling equipment and infrastructure to supply power, along with automated fire extinguishing systems. It is essential to take backups periodically to ensure operability and high availability. The more critical software and hardware, more efforts are needed for

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:

Cloud computing allows organizations to utilize virtual recourses; like virtual machines, storage, and applications. Rather than building and maintaining

Since all locations are independently connected to the Internet, file sharing is difficult among sites.

In this world everyone is selfish for somethings, even though in the positive reinforcement.People do have two sides the darkest and the brightest, people show their darkest side when they lose their self-esteem, everything seem unhappy to them they convince themselves that they do not have any value in this world and nobody cares anymore they all alone even though they start neglecting surrounding happiness. Those who have brightest side those who know how to seek happiness, give value to others and take positive outcomes. “Just as treasures are uncovered from the earth, so virtue appears from good deeds, and wisdom appears from a pure and peaceful mind”(Buddha). It explain that you need to focus on your goals that how your real personality, be calm to get positive outcome and the happiness will be appear in your way.

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.

This business case investigation discusses in depth about the process of virtualization of servers in an organization and the various benefits of doing so. Giving a brief introduction to the concept of virtualization, it was introduced in the late 1960s when the resources of mainframe computers were divided between several applications. [1] The term virtualization has since then been expanded in terms of practical application. The conversion of the physical server into a pool containing several virtual machines which act individually as one computer is known is hardware virtualization.

Carlson Companies, a private company known for its existence in marketing, business, leisure travel, and the hospitality industries, has over 180,000 employees across the United States. Carlson Shared Services, the Information Technology (IT) division, provides services to its internal clients and thus must support a wide range of applications and services. In 2002, the IT division decided to implement a storage area network (SAN) that in turn would meet the six (6) goals established in order to meet the needs of a growing company.
