...ITDM IT WATCH ON VIRTUALIZATION SUBMITTED BY GROUP 9 CONTENTS 1. INTRODUCTION TO VIRTUALIZATION 2. TYPES OF VIRTUALIZATION 3. ADVANTAGES OF VIRTUALIZATION 4. VIRTUALIZATION IN INDIA 5. REFERENCES INTRODUCTION 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. In layman's term, virtualization allows you to run an independent operating system within an existing operating system using the existing hardware resources. So if you want to learn another operating system like Linux, you can use virtualization to run Linux on top of the existing operating system. Virtualization is the abstraction of IT resources, separating their physical instance and boundaries from their function. Virtualization has brought important innovation to IT Virtualization concept was first developed by IBM in the 1960s to fully utilize mainframe hardware by logically partitioning them into virtual machines. These partitions will allow mainframe computers to perform multiple tasks and applications at the same time.. During the 1980s and 1990s, desktop computing and x86 servers become available and so the virtualization technology was discarded eventually. Client-server applications and the emergence of Windows and Linux made server computing significantly inexpensive...

...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...

...Running Head: Virtualization How will virtualization change the way government agencies do business in the future? Virtualization Abstract: Server and application virtualization is a hot topic among many government information technology program managers. Today’s government agencies are focusing on reducing expenses while improving the capabilities that information technology provides its customers. This is a difficult task to accomplish with shrinking budgets. A key technology that can help reduce costs in multiple ways is 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. There are many advantages and disadvantages associated with virtualization. Each government agency that is considering virtualization needs to investigate both aspects and make the informed decision according to their business needs and their customers. Depending on the environment that some agencies operate in, virtualization may not be a logical or realistic choice for many of its information technology needs due to security policies that may be in effect. This is especially true within the intelligence community (IC) and Department of Defense (DoD) where they are required to keep different security classifications of data physically separated. Even though system security classification and policy effect government IT environments, the emergence...

...to establish the security of virtualized servers compared to the physical servers. The paper determines the value of virtualization in the computer architecture of today’s world which is designed to run on a single operating system and therefore, most of the computer resources are left underutilized. The focus would be to determine whether the virtualized servers are more secure than their physical counterparts giving the advantages of virtualization therein. Virtual servers over physical servers Virtualization entails the obstruction of physical resources away from their underlying logical resources to improve flexibility and agility, reduce costs and therefore, improve the value of the organization. In a virtualized context, computing environments can be dynamically expanded, created, moved or shrunk as demand varies. Server Virtualization entails allocating several occasions of an operation system to run simultaneously on a single server. Virtualization of servers is achieved by applying a hypervisor to allocate logically and separate physical computer resources. The hypervisor enables a guest operating system to function as if it were solely in control of the hardware while running on the virtual machine, oblivious that other guests are sharing it (Bakshi & Yogesh, 2010). The security benefits of virtualized servers over physical servers Virtualization of servers in the current world is surrounded by a very sophisticated management infrastructure that enables the user...

...Seabreeze Virtualization Adoption Plan Bob Western Governors University Seabreeze Virtualization Adoption Plan The city of Seabreeze has had the misfortune of decreasing revenue for the past several years and is in desperate need of some cost saving initiatives. The solution must not impact services currently delivered to its citizens. Information technology (IT) is one of the services that must be maintained during the financial reductions. Because the city relies heavily on the use of IT to provide government services elimination of existing infrastructure is not an option. An alternate solution is essential in order to reduce the total cost of ownership (TCO) of the city’s IT equipment by providing newer technology that will have a higher return on investment (ROI). The option identified to fulfill this need is the adoption of virtualized servers, storage devices, and desktop computers. The conversion to virtualized environments will result in substantial cost savings as well as providing enhanced security, greatly improved disaster recovery, a more competent IT staff, and a smaller carbon footprint. 1. Benefits of Virtualization Virtualization is “the process of creating a virtual, rather than physical, version of something” (Virtualization, 2015). In the IT industry this refers to technology that utilizes software to imitate hardware and create virtual computer systems. One example of this is to use a single physical device such as a server and logically...
