A Comprehensive Study about Cloud Computing Security: Issues, Applications and Challenges.

Cloud computing provides facilities for users to save their data or information in servers which are connected through Internet or Intranet. Further, users can run their applications with the help of software provided by cloud computing servers without installing that software in their own personal computers. Since many users access to cloud computing servers for various goals, therefore one of the main problem in this regard is providing security in access, usage, share or running users’ programs by cloud computing sources or servers. This paper attempts to study security issues, applications and its challenges on cloud computing.
