Cloud Computing

On demand or on pay per use of resource such as: network, storage and server these all facilities are provided by cloud computing through internet is called cloud computing. Although, cloud computing is facilitating the Information Technology industry, the research and development during this arena is yet to be satisfactory. Our contribution in this paper is an advanced survey, that specialize in cloud computing concept and most advanced research issues Our contribution in this paper is an advanced survey that specialize in cloud computing concept and most advanced research issues. This paper provides a better understanding of the cloud computing and identifies important research issues during this burgeoning area of computing. Section 1 contains the introduction, within the section 2, we offer an summary of cloud computing, section 3 contains the safety architecture and section 4 will specialise in the research issues and security issue. We conclude the paper on section 5 along, side references.
