This study systematically examines cloud computing adoption by small and medium-sized enterprises (SMEs), focusing specifically on the driving factors and related theoretical frameworks. It employs a systematic literature review (SLR) to identify and analyse the existing literature on cloud computing adoption among SMEs. Two popular databases, Web of Science (WoS) and Scopus, were used to retrieve the records of publications from 2014 to 2024. Records were filtered through full-text journal articles written in English. Various factors from various models, mainly the Technology Organisation Environment (TOE), Diffusion of Innovation (DOI), Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT and UTAUT2), and Information Systems Success Model (ISS). It also identifies emerging themes through an analysis of relevant literature. The primary focus is on the underexplored context of Sri Lankan SMEs, specifically, the capability of cloud computing to improve their performance. Only full-text journal articles indexed in WoS and Scopus were considered, and those published before 2014 were excluded. This study adds to the comparatively limited knowledge in the literature on cloud computing adoption among SMEs in developing countries by offering a comprehensive synthesis of the important factors impacting this adoption. It provides important insights for researchers and practitioners while setting a new direction for future research.
