...Virtualization and Its Benefits Virtualization and Its Benefits AITP – Research and Strategy Advisory Group Christine, Leja, CCP, Chair Richard C. Barnier Charles L. Brown, CCP Paul F. Dittmann Paul Koziel Mark Welle J.T. Westermeier, JD, CCP Abstract Virtualization provides many benefits – greater efficiency in CPU utilization, greener IT with less power consumption, better management through central environment control, more availability, reduced project timelines by eliminating hardware procurement, improved disaster recovery capability, more central control of the desktop, and improved outsourcing services. With these benefits, it is no wonder that virtualization has had a meteoric rise to the 2008 Top 10 IT Projects! This white paper presents a brief look at virtualization, its benefits and weaknesses, and today’s “best practices” regarding virtualization. The Association of Information Technology Professionals (AITP) recommends these “best practices” to obtain the benefits that virtualization offers.

...Cisco Virtualization Experience Infrastructure (VXI) Reference Architecture October 5, 2010 What You Will Learn Enterprise IT departments are pressured to control costs, improve manageability, enhance security, and speed-up the deployment of new capabilities while supporting a consistent user experience across diverse endpoints. Desktop virtualization (DV) has become a popular solution for addressing these needs. With hosted DV, the end-user’s desktop experience (operating system, applications, and associated data) is abstracted from the physical endpoint and centralized. The user’s desktop image is hosted as a virtual machine on a data center server. Users can access hosted virtual desktops from anywhere through DV appliances, smart phones, tablet computers, laptop and desktop computers, and other clients. Organizations deploying DV face many challenges, as the DV technologies potentially affect the entire IT infrastructure. To address these challenges, Cisco has developed Cisco® Virtualization Experience Infrastructure (VXI), a comprehensive architecture for desktop virtualization. Cisco VXI, which uses three existing Cisco architectures, includes designs for virtualized data centers, virtualization-aware borderless networks, and virtualized workspaces, and the critical services needed to support these architectures. Cisco VXI reduces the total cost of ownership (TCO), streamlines operations, simplifies management, and positions organizations for growth. This document describes...

...| | With so many features called by differing names in each virtualization platform, comparing Microsoft and VMware virtualization solutions can sometimes seem a bit like comparing apples and oranges. But, I’ll try to boil things down to a real-world perspective based on my experience implementing both solutions in the field throughout my career. In this article, I’ll provide a summarized comparison of the feature sets provided by each of these latest releases using the currently available public information from both Microsoft and VMware as of this article’s publication date for additional reference. How to compare? Rather than simply comparing feature-by-feature using just simple check-marks in each category, I’ll try to provide as much detail as possible for you to intelligently compare each area. As I’m sure you’ve heard before, sometimes the “devil is in the details”. For each comparison area, I’ll rate the related capabilities with the following color coded rankings: * Supported – Fully supported without any additional products or licenses * Limited Support – Significant limitations when using related feature, or limitations in comparison to the competing solution represented * Not Supported – Not supported at all or without the addition of other product licensing costs In this Essay, I’ve organized the comparison into the following sections: * Licensing * Virtualization Scalability * VM Portability, High Availability and Disaster Recovery ...

...Virtualization Across the Board CIS512 Enterprise Architecture 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 maintenance personnel. In order to justify this risk, the return on investment had to be exceptionally strong and the company would require excess free capital. All virtualization services are offered without the need for any capital outlay or lead time; once a subscription plan is worked out, the resources are automatically available through any internet connection (Kishore 2012). For companies with existing IT departments, additional servers or services can be brought online immediately and seamlessly. The services offered also allow businesses to enjoy economies of scale, even for miniscule implementations. This also means that companies have access to the latest technology upgrades and updates along with security features and protocols without having...

...Assignment 3: Virtualization across the Board Chris Brown Strayer University CIS512 Dr. Gideon U. Nwatu ABSTRACT Virtualization is simply when a virtual version of a device or resources such as server, a storage device, network or even an operating system, which divides the resources into one or more execution environment is created. Virtualization has provided greater efficiency in CPU utilization, save energy (less energy consumption), greener IT, and better management through central environment control, reduce project timelines by eliminating hardware procurement, improved disaster recovery capability. Virtualization is sure the best innovation in the IT environment of the present age. The core idea behind virtualization is to make efficient use of hardware resources, such as CPU, memory and disk. In any computing environment it’s highly unlikely that hardware resources are being used to their full capacity. For example a typical desktop does not use more than 10% of its hardware resources under normal operational conditions. By using hardware virtualization, we can more effectively distribute our hardware resources among multiple virtual instances of operating systems according to that particular environment computing needs. Virtualization provides a mean to dynamically allocate hardware resources when needed and essentially unbinding software from hardware. Thus bringing down the overall requirements for hardware, which ultimately result in reduction of...

...About VDI VDI (Virtual Desktop Infrastructure), also refereed to as desktop virtualization, is a system that moves the user’s desktops to the What is VDI? VDI stands for Virtual Desktop Infrastructure, using software to virtualize desktops, then deliver that user experience centrally. Instead of users storing their OS, desktop personality and data on individual laptops or desktops, VDI enables desktop data to run centrally on servers maintained by IT admins, and just accessed locally via a traditional PC or a thin client (a network-connected device designed to access VDI images remotely). Other Benefits of VDI •Desktops can be set up in minutes, not hours •Client PCs are more energy efficient and longer lasting than traditional desktop computers •IT costs are reduced due to a fewer tech support issues •Compatibility issues, especially with single-user software, are lessened •Data security is increased http://www.purestorage.com/applications/vdi/what-is-vdi/ What is VDI?

The previous owner, Sam Yosemite, tells his IT team to provide support and information to your IT staff to help with the transition to your forest domain. Gathering information from the other writing assignment descriptions, decide the best ways to bring the “Wild Frontier” network into your domain, “Foghorn Leghorn” and migrate to your current standards. The business acquisition is largely superficial and the existing personnel structures will remain in place. You have to bring the “Wild Frontier” under the “Foghorn Leghorn” domain and make sure production needs are met at all the satellite locations. Your budget is fairly generous due to allocated funds for the transition, but will likely be much more constrained in the future.

...without being present. This is the concept of virtualization. “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”. The virtualization innovation has assisted companies in a positive way, but also can inflict negative wounds to the organization. Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. The 1960s was when virtualization was first deployed by IBM, itts main purpose was to operate mainframe hardware through separating them into virtual machine. In the 1980s and 1990s virtualization was not needed due to the growing numbers of desktop computing and x86 servers. New issues came to rise such as soaring maintenance and managing cost which lead to the creation of virtualization for x86 platform. Virtualization significantly drops general IT costs. Virtualization permits you to run several operating systems on a single computer. In July 2006 Microsoft made public a free Microsoft Virtual PC 2004 which is a windows hosted virtualization program. The latest version is combined with Windows 7 operating system (http://www.infobarrel.com/History_of_Virtualization). Today’s powerful x86 computer hardware was designed to run a single operating system and a single application. This leaves most machines vastly underutilized. Virtualization lets you run multiple virtual machines on...

...VMware In Class Case Analysis Question 1 From my perspectives, the main sources of VMware’s competitive advantage are immense lead in the virtualization market, high investment in R&D department, a large number of technology alliances and distribution networks, a strong hold on the high-end segment, high customer satisfaction, advanced hypervisor platform and server-based virtualization technology, large installed base and high switch cost for existing customers. So how is that advantage linked to the strengths and weakness of virtualization technology for VMware? Since VMware now has the immense lead in the virtualization market and high customer return on investment helps the company to sustain the lead, it has more money to invest in R&D department and able to attract and form more partnerships with other companies thereby making VMware continue playing a competitive role in the virtualization market. In addition, since VMware has large customer installed base compared with Microsoft and other companies and the switch cost for people who use their VMware’s management tool and build operations around that is pretty high, it has the opportunity to sustain the lead for a long time and build customer loyalty. VMware also suffers from its weakness of virtualization technology. The weakness may include performance penalty especially for a hosted architecture which requires three layers of software to run any application and the possibility to make the system more complex...
