Cloud Computing Models: Background, Data security, & Security Issues

Cloud computing is getting popular ,cost effective ,powerful resources over internet and rapidly growing area in last few years. Cloud Computing is more growing and features mentioned above encourage the organizations to shift their applications and service to cloud and grid. For the sharing resources that contains software, applications, infrastructures, cloud computing is the main key. Cloud computing has brought remarkable potential changes and good opportunities to information technology industry. A major concern in cloud computing is towards its security and privacy. Security issue is organized into many categories:- Data portability, Data protection, Reliability and ownership. However, most existing Cloud Computing platforms have not formally adopted the service-oriented architecture (SOA) that would make them more flexible, extensible, and reusable. By bridging the power of SOA and virtualization in the context of Cloud Computing ecosystem, this paper presents the existing issues in cloud computing. Proposition of solution for these issues has been provided also
