This paper gives an overview on cloud computing security. To clarify cloud security, a definition and scope of cloud computing security is presented. An ecosystem of cloud security is shown to illustrate what each role in industry can do in turn. Then security impacts of cloud security for both customers and operators are analyzed. To overcome challenges from cloud security, many state-of-the-art technical solutions, e.g., continuation protection mechanism, IDM, data security, and virtualization security are discussed. Finally, best practices on perspective of operator are summarized and a conclusion is conducted.
