Understanding Key Enablers of Cloud Computing Adoption and Acceptance Over Time

Cloud computing has been increasingly implemented in various industries due to its benefits, e.g., more cost effectiveness, improved mobility and manageability, and enhanced content sharing. In Thailand, the current national Information and Communications Technology (ICT) master plan focuses to move into the era of digital economy effectively with cloud computing. However, many concerns, e.g., data security have been raised considerably in Thai cloud-based environments. To gain more understandings, this research aims to provide insights into key enablers of cloud computing adoption and acceptance and to compare identified key enablers with two different time periods. A systematic literature review and questionnaire-based surveys were performed. The review result from 46 original papers reveal 12 key enablers influencing cloud computing adoption and acceptance. These enablers were then ensured in the Thai government context by collecting data from 274 respondents during July - October 2017 and 216 practitioners during May - July 2019. The data were analyzed by stepwise multiple linear regressions. The findings indicate that two enablers (i.e., clear cloud usage policy and appropriate plan) continuously had significant correlations with cloud adoption; while three enablers (i.e., clear cloud usage policy, appropriate plan, and cost effectiveness) constantly had significant correlations with cloud acceptance, in both 2017 and 2019.
