Cloud Computing has allowed for ubiquitous information access. There are several gateways for accessing information, with several ranges of mobility. Applications that work on the cloud must make data available thru any of these gateways, in a consistent manner. In this tutorial we introduce this multilevel paradigm of information access as well as showcase computational tools to achieve multichannel access.
