INTRODUCTION The economic case for cloud computing has gained widespread acceptance. Cloud computing providers can build large datacenters at low cost due to their expertise in organizing and provisioning computational resources. The economies of scale increase revenue for cloud providers and lower costs for cloud users. The resulting on-demand model of computing allows providers to achieve better resource utilization through statistical multiplexing, and enables users to avoid the costs of resource over-provisioning through dynamic scaling [12, 2]. At the same time, security has emerged as arguably the most significant barrier to faster and more widespread adoption of cloud computing. This view originates from perspectives as diverse as academia researchers [12], industry decision makers [35], and gov- 2. DISTRACTED BY DEFINITIONS The lack of a clear and widely accepted definition has posed a barrier to talking about cloud computing in general. Clearly “cloud computing" is an evolving term, defined more by usage than by written documents. That said, overly broad use has lead to criticism that cloud computing “include[s] everything that we already do" [21]. Similarly, splitting hairs on the precise definitions distracts us
