Cloud Computing Adoption Models in Organizations: A Survey

An organization’s ability to implement innovations that provide it with a competitive edge and improve efficacy, reduce expenses, and raise the calibre of its business operations determines its competitiveness. With the advent of cloud computing (CC), the distribution of information technology (IT) resources and services has experienced a paradigm shift. The cloud computing adoption model is a logical set of stages built to ease the transition from today’s traditional application delivery model to tomorrow’s use of cloud computing it is an advanced approach for technologies of adoption of cloud which enables benefits to be realized incrementally. The Technology Acceptance Model (TAM) is an effective adoption hypothesis that has been applied in a lot of research studies in the IT industry. The model considers the reason for which a person uses a system or application, and it suggests that Perceived Usefulness (PU) and Perceived Ease of Use (PEOU) serve as the primary drivers of IT adoption. TAM has demonstrated excellent adoption, use, and reproduction over time; nevertheless, the model did not provide crucial information on the user’s assumption to solely PU and PEOU. This constraint made it necessary to integrate or expand the model with other IT acceptance models. The Technology Organization Environment (TOE) framework puts forth a general list of adoption considerations for technology. Three contexts are examined under the TOE framework: technology, organization, and environment. While the meaning of the TOE system is also seen as clarifying technology adoption, TAM and its comprehensive forms have a high ability to clarify the reception of innovation. Combining these two models results in a newly designed and innovative redesign that advances and encourages more comprehensive, informative, and foresighted focal points of IT adoption by elevating the TAM and TOE models. Hence, the individual implementation or combination of the two models which harmonize the different components have been proposed by researchers. This paper presents a review of theories of cloud computing adoption and also discusses the challenges and possible solutions.
