A Review Of Cloud Computing Open Architecture And Its Security Issues

Abstract-Cloud computing is beginning from the development of parallel computing distributed computing shared computing and grid computing. For the sharing resources that contains software applications infrastructures and business processes cloud computing is the main key. Cloud computing has brought new tremendous changes and good opportunities to information technology industry. Cloud computing is a fast growing information technology has aroused the concern of the whole world. This is a favorable situation to study and application of cloud computing related technologies. 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 seven architectural principles and also introduces the existing issues in cloud computing. Proposition of solution for these issues has been provided also.
