The topic of Cloud Computing has gained in prominence in recent years. Our motivation to study this topic is inspired by observing many differences in opinion on aspects of Cloud Computing. We have a particular interest in exploring the drivers and barriers for Cloud adoption within organisations. This resulted in a vendor perspective research project with seven multinationals. In this paper, we present the findings of one section of this research, i.e. how companies identify what security considerations are required, what governance issues exist and what are the risks involved. The findings from this research show that much work remains to be done to facilitate SLA’s. New standardised SLA models are needed and this is a significant barrier to wider adoption of Cloud Computing. Educational requirements of the security issues and risks to data are also highlighted. It is important to understand that there are limits to the delivery of online services and 100% availability is often not possible. Cloud migration projects can be fraught with danger and may carry a substantially increased level of risk. This work is part of a larger body of research in which we work towards developing a framework for the adoption of Cloud Computing.
