...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...

...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...

...benefits of virtualization would impact the city of Seabreeze. There are many benefits to migration of a datacenter to a virtual environment. The most understated benefit is true power savings. The reduction of the overall hardware footprint literally means the organization doesn’t have as many servers or desktops to power on a daily basis. These saving which have to be measured over time will contribute to a sizeable decrease in power consumption. As a result of a reduced footprint, less space will be required to house required hardware since multiple servers can be housed on a single hardware host. After virtualization the amount of time to provision a new server is reduced from sometimes weeks to minutes. There is no new hardware to purchase. Only an operating systems license is required if the chosen OS is not free. Server uptime is also increased because of High Availability and Disaster recovery features that are built-in to the product. Explain how to offset potential negative implications of the adoption of virtualization for the city of Seabreeze. The biggest concern for most pre-virtualization users is fear. The fear of cost and application compatibility were some of the largest obstacles for early adopters. Over the years this has changed tremendously. One of the biggest opposing companies to virtualization was Oracle. They refused to support or adopt any form of virtualization for their products. A company the size of Oracle steered away from the virtualization path for...

...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...

...Virtualization is a technology which allows one physical server to run many virtual servers. By virtual server, I mean a software container that contains a full operating system and set of software, just like a traditional server would. Each virtual server “believes” that it is running on physical hardware, and thus any software you would run normally on real physical machines will work without modification in a virtual server. Furthermore, each virtual server appears to the outside world – to clients which connect to them – to be traditional physical machines with dedicated hardware. The operating system of the physical server provides hardware interfaces to the virtual servers via simulation in softwre: CPUs, hard drives, network interfaces, displays, CD roms, etc.. The physical server translates I/O to these virtual devices to the I/O to the requisite physical devices, if necessary. The resources allocated to virtual machines can be changed nearly on-demand (disk, memory, network interfaces); most operating systems need merely to be rebooted in order to see the new resources. Limiting factors in how many virtual machines an individual virtualization server can run are simply how much memory, disk space and network bandwidth the virtualization server has available to it, and to how many resources each virtual machine consumes. A very basic virtualization server could host eight to twenty virtualized machines. Furthermore, most implementations of virtualization...

...The Mist: Securing Cloud Storage Dinesh Devkota1 Travis McAdams2 Dr. Ihssan Alkadi3 Dr. Ghassan Alkadi4 Dr. Theresa Beaubouef5 Introduction In the past, people would run applications on their local machines, with data stored in same physical location. Today, people are moving to “the cloud” to run those application and store their data. Since data is valuable, security is essential in a world where one’s data is stored in the public domain. It is important to be aware of the physical locations where data is stored and the laws that impact rights to that data. The Mist Security Algorithm Technology & Implementation We utilized VMware's virtualization platform in concert with an enterprise grade server to meet our goals of building this solution on the latest enterprise software and hardware infrastructure. • Hardware: • Dell PowerEdge Server • RAID 1 Data Store • Hypervisor: • VMware ESXi 5.5.0 • OS: • Debain 7.2 (Wheezy) • Apps: • Apache • MySQL • OwnCloud Traditionally, people are provided with email verification, phone verification, and security questions as verification for resetting forgotten passwords. “The Mist” implements an enhanced security question verification algorithm that allows users access to their accounts and data. http://scale.wpengine.netdna-cdn.com/wp-content/uploads/2013/05/ILLUST_Cloud_Syncing_0723-1024x869.png http://cdn3.techworld.com/cmsdata/products/3230674/VMware_Stack.PNG • What if a copy of your data is located in a region where...

...California. In addition to the core entities, Riordan Manufacturing has a joint business venture located in Hangzou, China. Investigation into the company’s operating procedures and expenses revealed several shortfalls requiring immediate attention. The implementation of a streamlined Enterprise Resource Plan (ERP) and Electronic Database Interchange (EDI) is expected to reduce operational costs by 10% while improving cycle time by 15%. The finance and accounting departments are struggling with their existing record keeping and database configuration. The resources identified at each facility are made up of disparate and antiquated equipment. Current operations for the consolidated close of the General Ledger are completed, at a minimum, 15-20 days past deadline. Additionally, the current system adds unnecessary administrative costs for personnel re-adding documents that are manually written or not compatible with HQ IT systems. Monthly audits are daunting, costly, and labor intensive. Additionally, there is an immediate need for government compliance to meet the specific demands of that customer base. The entire financial and accounting focus can benefit greatly and exceed current operating goals by the implementation of a standardized and modern information system upgrade.
