Cloud computing is the latest effort in delivering computing resources as a service. It represents a shift away from computing as a product that is purchased, to computing as a service that is delivered to consumers over the internet from large-scale data centres – or “clouds”. Whilst cloud computing is gaining growing popularity in the IT industry, academia appeared to be lagging behind the rapid developments in this field. This paper is the first systematic review of peer-reviewed academic research published in this field, and aims to provide an overview of the swiftly developing advances in the technical foundations of cloud computing and their research efforts. Structured along the technical aspects on the cloud agenda, we discuss lessons from related technologies; advances in the introduction of protocols, interfaces, and standards; techniques for modelling and building clouds; and new use-cases arising through cloud computing.

challenges. Our paper aims to provide a comprehensive review of the academic research done in cloud computing and to highlight the research agenda academia is pursuing. We are well aware that a survey in such a fast moving field will soon be out of date, but feel such a survey would provide a good base for the 1st ACM Symposium on Cloud Computing to set new work in context with, and that it can act as a resource for researchers new in this area. Research in this field appeared to be split into two distinct viewpoints. One investigates the technical issues that arise when building and providing clouds, and the other looks at implications of cloud computing on enterprises and users. In this paper we discuss the advances and research questions... [continues]
