This study investigates the influence of environmental turbulence and cloud computing capacity on the strategic agility of various firms, distinguishing between government and non-government entities. Predicated on the framework of dynamic capabilities and contingency theory principles, it explores the correlations between environmental turbulence, cloud computing capacity, and strategic agility. The study draws upon data from 366 e-Commerce businesses in Thailand, comprising 213 government and 153 non-government organizations. Regression analysis is utilized to evaluate variables about the validity and reliability, and to test hypotheses. The findings indicate that cloud computing integration significantly impacts all models, whereas cloud computing flexibility affects only models 1 and 2, and market turbulence only impacts model 1. Technological turbulence shows no significant effect on any model. The study suggests that corporations should prioritize enhancing their cloud computing capabilities to foster strategic agility and fulfill their strategic objectives. The study further recommends expanding the scope of future research to diverse sectors or geographical regions, to verify the applicability of these findings across a broader business spectrum.
