...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...

...What is Cloud? The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something which is present at remote location. Cloud can provide services over network i.e. on public networks or on private networks i.e. WAN, LAN or VPN. Applications such as e-mail, web conferencing, customer relationship management (CRM), all run in cloud. What is Cloud Computing? Cloud Computing refers to manipulating, configuring, and accessing the applications online. It offers online data storage, infrastructure and application. We need not to install a piece of software on our local PC and this is how, the cloud computing overcomes platform dependency issues. Hence, the Cloud Computing is making our business application mobile and collaborative. Cloud Computing Technologies There are certain technologies that are working behind the cloud computing platforms making cloud computing flexible, reliable, usable. These technologies are listed below: * Virtualization * Service-Oriented Architecture (SOA) * Grid Computing * Utility Computing Virtualization Virtualization is a technique which allows to share single physical instance of an application or resource among multiple organizations or tenants(customers). It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded. The Multitenant architecture offers virtual isolation among the multiple tenants and therefore, the organizations...

Overall Conclusion Proposal/ Problem Statement Going to the doctor’s office for an appointment can turn into a very long and tiresome affair. Upon arriving, you have to check in, only to wait in a very long line to put your name down. Next, comes the seemingly endless process of waiting to get your name called which often takes up to an hour on a busy day. Finally, after being taken to the examination room, there is yet another half hour wait. So, what ends up taking only about five minutes of the actual doctors time, leaves you with half the day gone. These issues of several different waiting periods are what many patients deal with and often lead to hesitation in actually making an appointment. The lackluster communications involved in this structure is what makes this a bad business to operate. Essentially, a doctor’s office is a business, and like any other business, customers are vital. However, in a fast moving society where the economy is struggling, time is money and many people do not have the luxury to sit and wait. These inefficient...

...in Green Clouds Gaganjot Kaur* *M.Tech,IITT College of Engineering & Technology, Pojewal, Punjab Abstract — Cloud Computing can be defined as dynamically scalable shared resources that are completely accessed over a network and the users have to only pay for what they use and can share internally or with other customers as well. The majority of cloud computing infrastructure currently consists of reliable services delivered through data centers that are built on computer and storage virtualization technologies. The goal of a cloud-based architecture is to provide some form of elasticity, the ability to expand and contract capacity on-demand. The implication is that at some point additional instances of an application will be needed in order for the architecture to scale and meet demand. That means there needs to be some mechanism in place to balance requests between two or more instances of that application. The mechanism most likely to be successful in performing such a task is a load balancer. The aim of this paper is to discuss the existing techniques of load balancing and elaborate the main points of the techniques that are helpful in reduction of power consumption leading a step towards green clouds. Green Cloud is an Internet Data Center architecture which aims to reduce data center power consumption, and at the same time guarantee the performance from users’ perspective, leveraging live virtual machine migration technology.

...and Cloud Computing Level 3 Shapes the Cloud Any Cloud Computing application or service exhibits two characteristics. First it uses virtualization to decouple the end user from the actual service and second it employs a pay-as-you-go business model. Virtualization is the key technology, while pay-as-you-go provides the business flexibility. Virtualization let’s users take advantage of a service without the concern of owning or managing the actual physical resources used to provide the service. From a business perspective this allows IT departments to take advantage of a multitude of technologies to cost optimize the way they deliver services. Regardless of the type of virtualization employed, one simple fact remains, the user must still be connected to the service via a very ‘un-virtual’, real, physical connection. The connection is the ‘cloud’ of cloud computing. Level 3 builds these clouds. Application Performance Enables Network Performance The network is often taken for granted, but in the realm of Cloud Computing, the network has become part of the application. IT managers want to gain the benefits of moving to the cloud, but they must be assured that their customers, the users of the cloud, will have a consistent application experience. By working with Level 3 those IT managers can be assured that we will match their applications to the right type of cloud. We have no vested interest in driving one type of connection over any other. We have no cloud applications...

MIS535 Management Applications of Information Technology Table of Contents Abstract 3 Brief Company Background 4 Discussion of Business Problem 5 High Level Solution 6 Benefits 8 Conclusions and Overall Recommendations 11 Summary 13 Abstract Corporate users of technology use a variety of technologies to get their work done. Over the last three decades, companies that create and manage data have implemented a wide variety of disparate computers systems, each slightly different. This makes maintaining these environments expensive and troublesome to expand and maintain. A potential solution to this multi-platform server sprawl is to consolidate from many to a few computing platforms. Once the application software is ported to these new platforms, we can begin to virtualize hardware. These are the prerequisites for cloud computing. This plan addresses these concerns in my current place of employment which has been experiencing this problem for over a decade. Based on industry publications and communications with my peers, it appears that many companies are experiencing these types of issues. The recession of 2007-2008 has been very difficult for IT firms. We’re doing more with less and it appears that the budgets won’t be significantly increasing for some time. ...

...LYT2-Task 3 Assess and Adopt a Virtualization Adoption Plan What is Virtualization? Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware, platform, operating system (OS), storage device or computer network resources. Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources. For example, a computer that is running Microsoft Windows can host a virtual machine within it and can load Linux (Ubuntu) that looks like a computer with the the operating system Ubuntu Linux. i.e. both operating systems Microsoft Windows and Linux can be loaded in the same machine with Ubuntu Linux is in the virtual machine. Ubuntu-based software can be run on the virtual machine. Server Virtualization: This refers to creating a server in the cloud for example Amazon Web Services where virtual servers can be created and can be accesses as a service. 1. Description about how the benefits of virtualization would impact the city of Seabreeze. The city has a Physical server environment which consists of 72 servers, the storage environment of DAS (Direct Attach Storage) and 350 desktop or end computers. This setup can be virtualized by purchasing space for storage, server and end computing. This...

...Explain how the 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...

...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.
