Cloud computing aims to provide services and resources on a pay-as you-use basis with additional possibilities for efficient adaptation of the required resources to the actual needs. Cloud networking extends this approach by providing more flexibility in the placement, movement, and interconnection of these virtual resources. Depending on the use, customers however require the data to be located under a certain jurisdiction. To ensure this without the need of trusting the cloud operator, we propose a geolocation approach based on network coordinate systems and evaluate the accuracy of three prevalent systems. Even if the cloud operator uses supplemental measures like traffic relaying to hide the resource location, a high probability of location disclosure is achieved by the means of supervised classification algorithms.
