In the paper Overview and Analysis of Cloud Computing Research and Application published by Yizeng Chen etc. , authors summarize definition, characteristics, classification and challenges.
They pointed out a definition which has been generally accepted is that Cloud Computing is the developing result of Grid Computing, Distributed Computing, Parallel Computing, Utility Computing, Network Storage technologies, Virtualization, Load Balance etc. traditional computer technology.
There is not too much fresh ideas in this paper, but it reminds me reconsider about the development trend of IaaS, PaaS and SaaS. Move computation processing and storage to the cloud and transfer user client to I/O port in order to reduce users' burden? Or maintain computing and storage in the local? It is a question.
