Virtualization Technology For Cloud Computing Essay

Cloud computing is one of the fastest growing segment of Information technology today. In simple words cloud computing means storing and accessing data and programs over the internet instead on the computer's hard drive which can be accessed from any part of the world if the individual are connected to the internet or a network connection is available 24/7. A simple example of cloud computing is g-mail. With the connection of internet through any medium we can send and receive emails.

Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any

Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of

Cloud computing has been the hottest buzzword in recent years and is continually to be one of the most popular felids in which not only IT industry but other industries like commence, geosciences, education, etc are interested and where hundreds of millions of dollars flood into. The whole term “cloud computing” is first introduced to the public media by Google ex-CEO Eric Schmidt on Search Engine Strategies Conferences in 2006 (Schmidt 2006). The generally accepted definition of cloud computing is developed by the U.S. National Institute of Standards and Technology (NIST):

Cloud computing combines a number of computing concepts and technologies in objective to provide secure, quick, convenient data storage and net computing service with all computing resources visualized as services and delivered over the internet. Cloud computing has brought financial benefits and promises to many business and organizations a way to enhance their information technology such as collaboration, agility, scalability and availability without heavy upfront capital costs in servers meanwhile achieving minimal management effort for service providers.

The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

When a user want to use the services provided by cloud, its request is placed in the form of virtual machines in datacenter on currently active physical machine fulfilling the requirements specified by the user in such

Cloud computing is an ever expanding part of the IT industry, it is quickly being adopted by more ICT businesses due to it’s

Until 2008, internet had been represented on network diagram by a cloud symbol. Later variety of new services started to appear and permitted computing resources to be accessed over internet termed cloud computing. Cloud computing encloses activities like the use of social networking sites as well as other forms of interpersonal computing ; however most of the time cloud computing related with accessing online software applications, data storage and processing power. Clouding computing can

Abstract—Cloud Computing is a shared Information Technology infrastructure in which computing resources are shared among several systems that are connected together, using a network of servers. This type of resource sharing is facilitated by the Virtualization technology that enables multiple operating systems to run simultaneously on a single server (Multi-tenancy). Although this method provides optimization in hardware utilization, it may also result in unauthorized interactions which could lead to a number of risks such as jeopardizing the resource access control, denial of service attacks, Inter-VM (Virtual Machine) attacks and so on. In this paper, such possible challenges and risks and their corresponding effects will be studied, after which, several techniques and strategies will also be examined in order to tackle the Virtualization vulnerabilities. Possible architectural changes that can be made at the application and infrastructural levels will also be taken into consideration to enhance security in Cloud Computing.

Over the past several years, cloud computing has been getting attention as a new computing model for providing flexible and on-demand infrastructures, platforms, and software as services. Cloud computing is a technology through exchange of information and software management. Cloud computing allows users to use computer technology without the installation in their computers. It allows users to access their files or data from any computer having an internet connection. Cloud computing provides more efficient computing by centralizing data storage, processing and bandwidth. This technology emphases on virtualization of the host server or the controlling computer. The server acts as a communication network through which information could be shared. The information can be stored, retrieved and shared as and when required through a widespread global platform.

Abstract. Cloud computing is the upcoming generation of computation. Internet based computing is known as cloud computing, where software and hardware resources provided to the user on demand. Cloud computing is new paradigm that uses dynamically scalable shared resources e.g. networks, servers, storage, applications and services. It provides different cloud services through which resources can be swiftly providing and released with minimum management efforts. In this paper, we aim to pinpoint the types of cloud, services and difference that shows how effective cloud computing from other paradigm (Grid computing, Utility computing and Mainframe). Last, we will provide an overview on the various challenges and risk associated to cloud computing that deserves future research.

Cloud computing is the convergence of Virtualization and Utility computing. In early days of computing, both data and software were fully contained on the same user machine. Cloud computing eliminates the need for

Cloud computing is an emerging technology these days. Cloud computing is the development of distributed , parallel ,grid computing and virtualization technologies.In this paper,we actually explore the architecture of cloud computing as well as we explore distributed , grid and utility computing. We also address the several popular cloud computing platforms. In this paper, we aim to point the risks of cloud computing. We identified several challenges from the cloud computing adoption perspective. However, the biggest concern i.e.security and privacy issues are the strongest barrier for the users to adapt into cloud computing systems. In this paper, we investigate several cloud computing platforms and its architecture and risks.
