Virtualization and Cloud Computing

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.

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

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.

Cloud Services and Virtualization continue to grow in popularity but are they right for your business? These technologies can reduce overhead operation costs, improve utilization of resources and provide a level of flexibility to the organization’s Information Technology (IT) system. Understanding that these technologies do and their pros and cons is the foundation of choosing the right features for your business. Cloud services offer three types of services; Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) to meet the software, infrastructure needs of a business and provides them on a lease type of payment plan. Virtualization has three types of server virtualization, Full virtualization, Para-Virtualization and OS level Virtualization. Similar to Cloud services Virtualization types have features which may suit one business over another. Comparing the features provided by these technologies to total ownership of the IT system is also crucial in selecting the best services for your company as there can be an array of combinations of services contracted and internally owned features. While the perks of these technologies can be beneficial for an organization they should be carefully researched and tailored to the business strategic goals for

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.

Cloud computing is a “newsworthy” term in the IT industry in recent times and it is here to stay! Cloud computing is not a technology, or even a set of technologies – it’s an idea. Cloud computing is not a standard defined by any standards organization. Basic understanding for Cloud: “Cloud” represents the Internet; Instead of using applications installed on your computer or saving data to your hard drive, you’re working and storing stuff on the Web. Data is kept on servers and used by the service you’re using; tasks are performed in your browser using an interface/ console provided by the service. A credit card and internet access is all you need to make an investment in

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.

Moving from physical machines to Virtual machines can be a daunting task and many companies will take into account unforeseen issues that can be mitigated but there are instances that issues will arise and there are tested and tried methods available to move from physical to Virtual machines as well as hosting your own virtualized cloud. We are going to talk about some of the deployment methods as well as how cloud computing is going to be beneficial for the organization to include traditional Computing and our own computing. Will also contrast how major companies such as Amazon and IBM perform their migration and how companies will perform the migration on their own without their help. Next we will examine a few challenges as well as security concerns that might arise due to hosting your own cloud and migrating from Legacy servers and physical servers into newer virtualize machines.

Cloud computing is steadily increasing as a viable enterprise technology solution. Information technology literature reports an expected boost in enterprise adoption of cloud computing in the next few years. Business plans to transition operations to cloud computing are also commonly reported. Despite these trends, there are many businesses that remain skeptical of the benefits of cloud computing and continue to support information systems in an on-site location. Careful planning and due diligence is essential to ensure that the most beneficial cloud computing model is utilized to meet business needs. This use case explores cloud computing methods, reviews security concerns regarding virtualization, and considers mechanisms to better

The introduction of cloud computing infrastructure has brought in many changes to the infrastructure of any IT organization. Cloud computing has become the latest and most advanced infrastructure service to date. More and more companies are migrating to cloud computing service as days go, as they provide more flexibility and scalability and user friendliness in many aspects of an IT infrastructure.

The concept of virtualization is not new, nor is there minimal research on the subject. There is a plethora of research available for review along with a great amount of knowledge on the effect that virtualization has on knowledge sharing, globalization, and it’s effect up on businesses. Many say that issues such as time zoning, language, and other variables can increase the challenges on employees and company’s alike, but, there are also positives to this.

Technology is one aspect of business that can universally enhance any company’s capabilities and add resources to offer a positive impact on the bottom line. However, information technology comes with its own implementation barriers that can complicate matters when making IT investments with an expectation to generate a return on that investment. The biggest impact of virtualization in cost structures is the radical change in how technology is implemented and paid for. Previously, any new technology could require a capital investment, lead times for setup and training, and continuing overhead in the form of support and

Abstract – Cloud computing is a type of computing that relies on sharing a pool of physical and/or virtual resources (e.g., networks, servers, storage, applications and services), rather than deploying local or personal hardware and software. This technology is mainly service oriented and focuses on cost reduction, hardware reduction and pay just for service concept. Virtualization in cloud computing is making a virtual image of the storage devices servers or network resources so that they can be used on multiple machines at the same time.
