An Approach to Critical Success Factors in Designing Cloud-based Application Solutions

In recent years, Cloud Computing is one of the more influential technologies. Cloud users do not need to deeply understand the technical knowledge underlying the cloud infrastructure. System developers enable enterprises and organizations to quickly implement systems and deploy applications in the cloud environment, and also reduce the cost from development to maintenance. Hence, many companies have begun to use cloud-based systems. They need to consider related essential requirements during developing a comprehensive cloud-based application system. Therefore, this paper did survey functional and non-functional requirements to be divided into six facets. In the first stage, we invite scholars and experts to interview and fill out the questionnaire, and conduct a reliability analysis through Statistical Product and Service Solutions (SPSS) to make corrections in questionnaire of the first stage, and erase unnecessary influencing factors to select the critical success factors (CSFs). In the second stage, we will calculate the weight ratio and rank the sequence for each of the CSFs through the analytic hierarchy process (AHP). After performing two stages experiments, the final results indicate that Security and Privacy, System Performance, and Processing Features are the top three of the six facets. In the calculation of the overall weights of CSFs across the six facets, the top six ranked CSFs cover Data Accuracy, Reliability, Computing Logic, Robustness, Accessibility, and Data Privacy and Encryption. In the future, the proposed methodology can be applied to IoT and smart factors applications.
