While most research regarding adoption of cloud computing by companies covers countries with highly developed IT infrastructure, cloud computing is actually used also in less IT-mature countries. Still, companies address cloud computing differently in countries with different levels of IT-maturity. This research explores cloud computing adoption factors in less IT-mature countries having Turkey as the example. Embracing an exploratory approach, we investigated five large Turkish companies. The results show that the main adoption factors in favour of cloud computing are “cost”, “distributed organisational structure”, “mobility of the employees”, and “end-user satisfaction”, while “security”, “critical business processes”, “loss of control over data and systems”, and “technical infrastructure of the region in terms of broadband” are the factors that make companies cautious about cloud computing. The main difference between Turkey and more IT-mature countries with respect to cloud computing adoption factors is inadequate broadband access and lack of knowledge on cloud computing.
