Abstract
This chapter explores the impact of cloud computing on information systems (IS) performance through organizational agility. The research addresses a gap in fieldwork regarding how cloud computing enhances IS agility. Focusing on medium and large organizations in the MENA region, the study uses the Diffusion of Innovations (DOI) theory and the Technology-Organization-Environment (TOE) framework to identify key factors influencing cloud adoption. A quantitative study of 200 companies reveals that agility, cost-saving, security, privacy and trust, technological readiness, and data sovereignty significantly affect cloud adoption decisions. Additionally, interviews with 20 experts provide qualitative insights into how different cloud service models impact agility dimensions. These findings offer valuable guidance for decision-makers, helping them understand the effects of cloud computing on IS agility and make informed cloud adoption strategies.
