 Recent developments in cloud computing platforms have led to unique opportunities—and ethical challenges—for researchers. Cloud computing describes the deployment of computing resources via the Internet, providing on-demand, flexible, and scalable computing from remote locations. Examples include web-based email and calendaring services provided by Google or Yahoo, online productivity platforms like Google Docs or Microsoft Office 365, online file storage and sharing platforms like Dropbox or Box.net, and large-scale application development and data processing platforms such as Google Apps, Facebook Developers Platform, and Amazon Web Services.
