A Study of Security Structure System in Cloud Computing?

Security is the major obstacles of the long dreamed vision of cloud computing. The sensitive application data are moved into the cloud data centres and run on virtual computing resources in the form of virtual device. The user concerns about cloud computing is its security. Enterprise data centres, Internet Data Centres (IDC) and service provider’s offer racks and networks, and the remaining devices have to be prepared by users with servers, firewalls, and storage devices etc. Under cloud computing, the backend resources and management architecture of the service is top privacy for user. In cloud computing atmosphere security investigation and evaluation of privacy, security and trust issues by a quantifiable approach are the prime concern of security. In this paper we have discussed physical and logical security of cloud computing.
