Virtualization and Security in Cloud Computing

Abstract

Cloud Computing is becoming an integral part of Next generation technology & becoming up business and IT industry. It is the fastest growing technology nowadays cloud servers work on the technology that provides services on the demand to the users. Virtualization enhance resource availability helps to overcome the problems of Data loss, access & data security. This paper focuses on impact of virtualization technique, how it helps to expand the flexibility of resources in cloud environment, security threats and ways to tackle them components of virtualization, its types, hypervisor & application architecture that provides energy overhead, sustainability & usability of cloud virtualization. I.INTRODUCTION Over the year, IT technological uprise has brought up with a new lifestyle of people.Cloud computing technological innovation is one of them, Use of cloud servers has greatly increased because of its flexibility resources availability and per use way approach.A typical data for cloud computing would consist of thousands of servers & hundreds of thousands of hierarchically connected switches.According to studies reveal that Ideal system uses about 70% of energy.In order to reduces energy consumption & reach environment sustainability, application of virtualization technology in cloud computing is gathering momentum.The concept was firstly introduced in 1960 by IBM to provide concurrent, interaction access to main frame computer-IBM-360 which support many instances of OS running of same computer hardware platform.Now this technology innovation has gained momentum in its use by providing hardware independence cost saving, improved management, encapsulation & isolation.By the sharing computing resource through service provided by virtual machine, users can reduce the cost of hardware software.Virtual machine are utilized for providing service which can result high resource utilization, easy system upgrade & maintenance.This research describe new trends in achieving data networking centre for cloud computing & well as challenges in its attainment. II. CLOUD COMPUTINGCloud Computing is a frequent that we come across in IT, business and other related field.Generally, Cloud computing is a technology that can maintain data & application and across users to access their personal files and Data at any computers with internet access & a central remote servers.The technology allows efficient storage, processing & delivers hosted service over the internet.Cloud Computing offers reduced hardware maintenance & cost effective on demand service to users, without the need for large up scale front infrastructure investment.Basically, this technology can bring benefits to service provides as well as service users for service providers, they can service users, they don't have to worry about hardware & software maintenance & upgradation & pay on demand .Apple, Google, Microsoft, etc are the biggest cloud service provides that provide huge service & storage to there user.Background of Cloud Computing -History of Cloud Computing can be dated back to 1960s when John McCarthy wrote that "Computation may someday be organized as Publication ".The term cloud computing was first used by Ramnath Chellapa during in 1997.In 1999, Salesforce.com which was one a the first movers in cloud computing introduced the concept of delivering enterprise application via a simple website.Since then, different companies followed up to emergence of this technology like Amazon in 2002 launched Amazon webservice, then Google Docs & Amazon's Elastic compute cloud (EC2) as commercial web service in 2006.Next follow up that enhanced cloud computing to another level was collaboration between IBM & Google in 2007 Eucalyptus in 2008, followed by open Nebula, Microsoft in 2009 with Windows Azure.Currently Cloud Computing has become a main target for different software & IT Companies.22% 78% Do you know about Virtualization?yes no
