My review (with Edgar Whitley) of cloud computing is out in Journal of Information Technology in September/December, but before then the most recent review is:
Yang, Haibo and Tate, Mary (2012) “A Descriptive Literature Review and Classification of Cloud Computing Research,” Communications of the Association for Information Systems: Vol. 31, Article 2.
“We present a descriptive literature review and classification scheme for cloud computing research. This includes 205 refereed journal articles published since the inception of cloud computing research. The articles are classified based on a scheme that consists of four main categories: technological issues, business issues, domains and applications, and conceptualising cloud computing. The results show that although current research is still skewed towards technological issues, new research themes regarding social and organisational implications are emerging. This review provides a reference source and classification scheme for IS researchers interested in cloud computing, and to indicate under-researched areas as well as future directions.”
