...save money and one of those areas is technology. It is impossible to eliminate technology such as computers all together because it’s a big part of the city daily operations. One of the potential options is virtualization of city’s physical servers, storage devices, and end user computers would result in significant savings in cost to the city of Seabreeze. Benefits of Virtualization Virtualization is defined as a technology that uses software to run multiple applications and operating systems on one or more physical host servers all at the same time. Within the host server is comprised virtual computers known as VM (Virtual Machines) are running the operating systems and applications similar to a physical PC. VM are setup as virtual servers and virtual desktops. Below is an example how a virtualization server operates. Example of Virtualization Server One of the benefits of virtualization is consolidation of servers since the city has 72 physical servers. The physical servers could be reduced from 72 to 4 host servers due to virtualization. By consolidating the physical servers, it will reduce cost of maintenance, software licenses, and hardware. One example of cost savings, in 2009, Landmark Healthcare had 63 physical servers and used virtualization to replace them. Those servers were replaced with 3...

...Despite the larger physical space for network and storage area, we still cannot solve the issue we’ve been having. We are running out of storage space, and there’s just not enough physical space to accommodate the data we are generating. To make matters worse, accessing the stored data has been time consuming and a lot of time, system seems to be down when accessing the data. This proposal calls for implementing of network and storage virtualization to accommodate the data and high availability. Introduction According to Storage Networking Industry Association (SNIA), Storage Virtualization is a process of isolating the internal function of the storage system application so that it can be independently manage. Storage Virtualization adds the capability to lower the storage resources level and reduce complexity in the management process (Bunn, Simpson, Peglar, & Nagle). The word “Virtualization” is the virtual version of something instead of the actual physical. In this case the storage is the virtual of the actual physical storage. Virtualization had been utilized in many processes such as the partition of the physical hard drive into the logical section creates the image of the actual physical hard drive....

...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...

...Virtualization Success in the business world relies on the ability to overcome the competition on all levels. A highly competitive business will continually seek the best value for dollar weighed option available. Technology drives business entities to become more efficient and to compete on a world market. That’s were virtualization steps in. Virtualization provides a business with more effective solutions saving excessive hardware cost, more efficient time management, and overall improvement of system reliability. The standard model of technology infrastructure follows the rule of one application per server. For example, if an organization requires a database solution, a system administrator would design a solution to meet that requirement. This model has server our technology needs for decades but falls short in meeting the demands of fully utilizing the hardware (server). You are only using a small percentage of the computers capabilities and wasting the rest. As a result, technology has become more integrated into the most mundane of everyday activities, resulting in exponential growth of demand for capacity and processing power. Server virtualization breaks away from the standard model by allowing organizations to consolidate multiple applications and services to a single physical server, increasing capacity while lowering the operational costs. Virtualization allows organizations to enjoy a much greater amount of flexibility to respond to bother internal and...

...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...

...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...

...study Introduction Virtualization is one of the most exciting trends in the industry and one that has the potential, over the next few years, to change the model of how IT systems are deployed. But server virtualization will not only change how IT administrators and architects think about servers and system utilization, it is also going to affect the processes and tools used to manage what will certainly become an increasingly dynamic environment. Virtualization has actually been around for some time now, but the technology is still evolving. In fact, the word itself still means different things to different people. In broad terms, however, virtualization is about abstracting one layer of the technology stack from the next layer, like storage from servers or the OS from the applications. Abstracting the different layers, in turn, enables consolidation and better manageability. As a concept, virtualization applies to storage, networks, servers, applications, and access. When you look at storage and networks, the goal of virtualization is to aggregate a set of different devices so the total pool of resources looks and acts like a single entity. For example, you can configure a 40TB storage solution instead of a set of 20 2TB storage devices. But with other components, virtualization acts in the opposite direction, helping you to make a single system appear as though there are multiple systems. The most common example of this is server virtualization, where you host multiple...

...NETWORKING WEEK 5 ESSAY Microsoft and VMware Comparison Tyler Reed In today’s world of cloud storage, cloud computing, and virtualization; I think it is important to understand what virtualization is before comparing the different options. Virtualization first started in the 1960’s as a way to logically divide the system resources provided by mainframe computers between different applications. It is very important to remember that computer strength and hardware performance wasn’t as strong or efficient when this method was introduced. While today’s smartphones are inherently stronger than the best computer during that time, the base problem still exists. Mainly because of the amount of resources needed to run multiple applications, allow server access to potentially thousands of computers and devices accessing the same computer or hardware. Since the concept’s inception the meaning has broadened into hardware virtualization, mobile virtualization, and desktop virtualization. Virtualization has helped organizations reduce cost and increase efficiency in the data center. New virtualization products allow for different benefits and challenges and must be carefully considered for businesses to realize the long term benefits, such as increasing user productivity and decreasing IT costs. Microsoft has the largest range of desktop virtualization and management products that can be integrated into a flexible solution for many different scenarios. Microsoft uses a suite approach...

...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...

...Introduction The company that I work for has introduced and implemented Sever Virtualization technology but there is a very great concern in the security aspect of this implementation. So in this paper I will be discussing the security implications that are brought to the table by implementing Server Virtualization. Virtualization is a methodology that divides a computer’s resources into different environments and/or partitions. It was first developed in the 1960’s by IBM Corporation in order to partition a large mainframe computer into several logical instances running on one mainframe computer as a host .The main (and only) computer is called a host and multiple Virtual Machines can be created within the host. The VMs live independently of one another and different operating systems and applications can be loaded on each VM. Hypervisors play a significant role as far as resource allocation is concerned. Virtualization of servers has contributed tremendously to organization over the very short period since it was introduced to the IT and network environment. The organizations that have adopted this technology have gained a huge benefit in terms of cost savings, lower energy consumption, and the lesser space needed. Although this is very good and useful technology, the understanding of the importance of security enforcement still remains the cornerstone in the implementation of this technology. The introduction of newer and more complex environment triggers advancement as...

LYT2 TASK 3! 2 LYT2 Task 3 City of Seabreeze Virtualization Adoption Plan! Given the City of Seabreeze’s declining revenue stream and resultant financial situation, as well as simple good government, it is critical that the city find ways of reducing expenses while continuing to provide the services needed by the citizens of Seabreeze. This includes the city’s use of information technology. Technology investments cannot simply be eliminated, as they are a critical component of the city’s infrastructure on which key city services rely upon. Therefore it is necessary to identify technologies which can produce a greater return on investment (ROI) through reductions in the total cost of ownership (TCO) of the city’s technology assets. One approach that would meet this need that has been identified is the adoption of server, storage and desktop virtualization technology. These technologies not only represent a significant opportunity for the City of Seabreeze to reduce costs, but it will also enable the city to reduce its greenhouse gas emissions, raise IT staff efficiency, and improve disaster recovery capabilities.! 1. Virtualization benefits The term “virtualization” refers to technology that enables a single physical device, such as a server with a large pool of resources...

...1. Explain the difference between the three types of server virtualization using the first video. According to the first video, a virtual server runs on 3 virtual machines, with different operating systems and applications at the same time, such as, Windows, Unix, and Linux. This server does not need to realize that it’s running a virtualization environment. The second server is call a para-virtualization, which consist of 2 virtual machine. Each virtual machine version of operating system is modified to cooperate with the hypervisor. The two para-virtualized Linux offer a performance improvement. The third server is an operating system virtualization. This server creates their own form of virtualization at the current level. In these case, a virtual server are isolated from one another, but they all run the same operating system. 2. Why is virtualization important to a company like Hudson’s Bay Company? How did that factor into their decision to partner with IBM? Hudson’s Bay Company is a fast growing company that needed more power to run their operating system. Instead of having to add more server to their infrastructure IBM was able to provide HBC a blade server with a faster speed, which allowed them to do with less servers. The blade server has various capabilities, such as, multiple drivers on the blade in case of a failure of one driver, HBC can still be up and running. The server is a lot easier to maintain especially when it goes down. HBC can easily...

...from one another. The battle for server virtualization and cloud computing markets is at hand and either entity is giving up without a fight. VMware has been an extremely difficult company to beat when it comes to things such as stability, security and overall market share. Microsoft likes to show off its Heterogeneous hypervisor management capability where as VMware V Center lacks basic management functions for vSphere environments. VSphere host, resource pools and storage and networking are some examples. VMware also has an advantage over Microsoft by advising people that SCvMM requires vCenter Server to manage vSphere environments, which results in much higher cost and complex processes and procedures. VMare has had technology speak as its own voice while challenging Microsoft’s Hyper-V hypervisor which is becoming very competitive and becoming a new and rising threat in the server virtualization market. VMware solutions know that by now it is the time for them to act in order for them to maintain their competitive place in the market. So Which one of these are better? Bogomil Balkansky Vice president of product marketing, Virtualization and Cloud Platform at VMware product marketing, Virtualization and Cloud Platform at VMware states that vSphere wins because of the company’s big head start and track record of innovation.
