Adoption of cloud computing in organizations is increasing at a rapid pace. It is expected that the majority of the organizations in industrialized nations will be using cloud services to some extent in the near future. In this review I categorize adoption factors utilized in the literature and identify determinants playing a key role in organizations’ decision to adopt cloud. I analyze both quantitative and qualitative evidence and code relationships between factors and adoption of cloud by systematically reviewing the literature. Findings show underrepresentation of the factors related to organization and external environment in cloud adoption literature. This study contributes a set of determinants of cloud adoption, which serves as a foundation for the future research and advancement of the theories in information systems field.
