Data location compliance in cloud computing

Presently, Cloud Service Providers (CSPs) don’t always provide services which conform to this data location legislation, or in case they do, they don’t always show compliance to their customers. This study is about how CSPs can show conformity to customer demands regarding data location. Interviews with CSPs reveal that CSPs are presently in principle able to determine and control the location of data of their customers, e.g. making use of the configuration of the hypervisor. But, these CSPs don’t give guarantees about the location of data. This investigation proposes the Cloud Computing Compliance Guideline, dependant on interviews and literature study. The Cloud Computing Compliance Guideline offers a process description of showing compliance, which enables CSPs to show compliance to customer demands concerning data location…
