The success of cloud computing adoption depends on several factors. These include how well task requirements fit the features of the technology and how viable the technology is, based on economic feasibility, maturity of the IT infrastructure, and social readiness of the organization. The purpose of this paper is to study the adoption of cloud computing in business and the use of the fit-viability framework for assessing the likely success or failure of cloud computing in an organization. The study analyzes cloud computing adoption in four multinational software companies in order to explore the application of the fit-viability model (FVM). This multi-case analysis involved detailed interactions with project managers and senior managers in all four firms and the analysis of feedback data collected from them. The results indicate that cloud computing adoption in all the firms has a high fit with the task requirements and that most of the firms exhibit a high viability regarding the technology. The findings of this study would be helpful to the managers in understanding the fit and viability of cloud computing to perform their jobs and would further enhance the benefits of cloud computing in their organizations.
