Cloud-computing applications are fast replacing traditional mobile and desktop applications such as e-mail, document editing, or photo storage. Such applications may require ubiquitous network access that is not always available, e.g., in remote areas without infrastructure, but also in areas with infrastructure where the costs of access are too high for users, such as tourists who do not wish to pay high roaming charges. This paper explores the use of opportunistic networking in a ``Device to Device to Cloud'' architecture that gives tourists access to cloud computing resources via local users' network connections. We use real-world trace-driven simulations and a new tourist mobility model to evaluate two options: storing data at well-situated hubs versus exploiting the mobility of local users, and find that the latter improves message delivery performance.
