Abstract
Cloud computing is revolutionising the way software services are procured and used by Government organizations and SMEs. Quantitative risk assessment of Cloud services is complex and undermined by specific security concerns regarding data confidentiality, integrity and availability. This study explores how the gap between the quantitative risk assessment and the perception of the risk can produce a bias in the decision-making process about Cloud computing adoption. The risk perception of experts in Cloud computing (N=37) and laypeople (N=81) about ten Cloud computing services was investigated using the psychometric paradigm. Results suggest that the risk perception of Cloud services can be represented by two components, called dread risk and unknown risk, which may explain up to 46% of the variance. Other factors influencing the risk perception were perceived benefits, trust in regulatory authorities and technology attitude. This study suggests some implications that could support Government and non-Government organizations in their strategies for Cloud computing adoption.
Highlights
The risk perception of experts in Cloud computing (N=37) and laypeople (N=81) about ten Cloud computing services was investigated using the psychometric paradigm
We argue that risk attitude and risk perception may differ from quantitative risk assessment and can have an impact on the risk acceptability and adoption of Cloud computing services
Results show some differences in the risk perception of laypeople and experts, and contribute to identify other factors influencing the risk perception of Cloud computing services. 4.1 Perceived Risks The mean levels of perceived risk were compared between 10 cloud services and 3 non-cloud services
Summary
The risk perception of experts in Cloud computing (N=37) and laypeople (N=81) about ten Cloud computing services was investigated using the psychometric paradigm. Results suggest that the risk perception of Cloud services can be represented by two components, called “dread risk” and “unknown risk”, which may explain up to 46% of the variance. This study suggests some implications that could support Government and non-Government organizations in their strategies for Cloud computing adoption. It is expected that the cloud services market will provide innovative solutions for industryfocused platforms that will revolutionise how companies and organizations operate their IT and how they compete in their own industry [3]. In 2010, the UK Government was the first to introduce a Cloud strategy but despite the adoption of the “cloud first policy” the IT spending on cloud services in 2014 was €24.7 million in comparison to an overall IT Government spending of €5.89 billion
