Small and medium enterprises (SMEs) in the Sri Lanka information technology (IT) sector were surveyed using a questionnaire. The diffusion of innovation (DOI) by Roger and the unified theory of acceptance and use of technology 2 (UTAUT2) by Venkatesh, Thong, and Xu was used as the theoretical framework for evaluating the reference model. Two hundred fifty-six important IT executives from Sri Lanka companies participated in the study. Quantitative techniques of data coding and analysis were applied in this investigation. Statistical package for social sciences (SPSS) software is used for exploratory factor analysis, and analysis of moment structures (AMOS) software is used for confirmatory factor analysis, including bootstrapping for mediator analysis of BI. The results show that among seven hypothesised factors, three factors: relative advantage (RA), compatibility (CT), and complexity (CX), significantly influence BI to adopt cloud computing.

INTRODUCTION The adoption of cloud computing (ACC) is the latest phenomenon to be more productive in each industry. As cloud computing has already become popular across the globe and different people from different sectors use cloud computing for different reasons [1]. Traditional on-premises computing is shifting to the cloud, which benefits both businesses and individuals [2]. Sri Lanka is one of the fastest developing countries in Asia. Information technology (IT) is a rapidly growing industry among the other industries in Sri Lanka. The workforce of IT doubled over five years, and it has grown by 120% over the past five years, making it one of the highest growth areas in the economy [3]. Currently, almost all the small and medium enterprises (SMEs) in Sri Lanka use at least one cloud service, knowingly or unknowingly using the software as a service (SaaS). During the COVID-19 pandemic, all the traditional (office-based) work switched to working from home, and SMEs utilised it without any downtime to continue their business. The IT companies encourage employees to work from home by tunnelling staff through virtual private networks (VPN) or collaborative platforms. COVID-19 enables Sri Lanka SMEs employees with a new culture of work by working in the comfort of their homes by utilising cloud-based software. Technology acceptance is one of the major aspects that every individual or organisation is willing to adopt cloud computing in their business. Researchers have been trying to pinpoint what characteristics lead to the
